6 General information 1 General Information 1.1 Intended use The herborner.d with its 100% coating is particularly suited for use in swimming complexes, leisure and adventure pools, theme parks, industrial plants and shipping technology. The inline version of the block pump is intended for direct installation into a pipeline. The coating is approved for use in swimming pools and for drinking water, making it the right choice for just about any application. herborner.d model Coated inline close coupled centrifugal pump with IE2/IE3 motor herborner.d-pm model Coated inline close coupled centrifugal pump with permanent magnet motor herborner.d-c model Coated inline close coupled centrifugal pump with heat exchanger motor Each pump is solely intended for the purpose previously specified. Any other application or applications extending beyond the stated purpose or alterations made to the pump without prior written agreement with the manufacturer are not permitted. The manufacturer is not liable for damages resulting from unintended use. The operating company bears sole responsibility. Caution! Pumping any liquid which chemically attacks the pump material or contains abrasive ingredients can destroy the pump and/or the coating. Use bronze or stainless steel as the pump material for these media. The media used for the intended operation of the pump and the associated hazards are the sole responsibility of the operating company. Danger! Air bubbles or accumulations of gas around the mechanical seal create a potentially fatal explosive atmosphere. Provide a constant supply of pumped media to the supply and pressure pipes as well as to the interior of the pump that is in contact with the liquid. Provide appropriate monitoring measures to ensure this. Notice! Missing safety devices can damage the pump. The pumping station must conform to the respective directives and all safety devices must be installed and fully operational. Only then should the pump be put into service. Intended use also includes complying with the operating and maintenance conditions specified by the manufacturer. Danger! Pumping flammable or explosive liquids is life-threatening. Only use pumps of explosion-proof design (Ex) in potentially explosive atmospheres in accordance with the corresponding specifications. 1) Pumped medium free of H 2 S, up to 1000 mg/l of chloride ions 6

7 General information The explosion-proof centrifugal pumps satisfy the requirements of electrical equipment for use in potentially explosive atmospheres in accordance with Directive 94/9/EC of the European Council dated 23 March, 1994, for intended use in potentially explosive atmospheres for device group II category 2. Operational conditions for Zone I and Zone II. Explosion protection symbol Device group Device category Explosive gas atmosphere Temperature classes II 2G T1-T Product information acc. to Ordinance 547/2012 The MEI reference value for water pumps with the best efficiency is 0.70 The efficiency of a pump with a corrected impeller is usually lower than that of a pump with a full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) refers to the full impeller diameter. Operating this water pump at different duty points can be more efficient and more economical if it is controlled, for example, using a variable speed controller which adapts the pump operation to the system. Information on the efficiency reference value can be found at [ Information on disassembling and recycling or disposal after final decommissioning: Section 7.8 Disposal Reference value display for MEI = 0.7 and MEI = 0.4 can be found at [ Temperature class T3 means that the pumps also meet the requirements of temperature classes T1 to T2. Danger! Exceeding the limit values specified in the order and on the name plate can result in a potentially fatal explosive atmosphere. Comply with the limit values. The explosion protection marking on the pump refers only to the pumping component. The motor has its own explosion protection marking. 7

11 General information Impellers Closed multi vane impellers for clean to slightly soiled pumped media are used. Caution! Dry running the pump will destroy the mechanical seal! Ensure there is adequate cooling and lubrication for the sliding surfaces Installation The pumps can be delivered in various installations: Vertical installation of the pump Horizontal installation of the pump Danger! Air bubbles or accumulations of gas around the mechanical seal create a potentially fatal explosive atmosphere. Provide a constant supply of pumped media to the supply and pressure pipes as well as to the interior of the pump that is in contact with the liquid. Provide appropriate monitoring measures to ensure this. Horizontal installation of the pump with pump support. The optional Seal-Guard-System or ETS X4 (not Ex) permit monitoring of the mechanical seal to protect against dry running Drive Shaft sealing For operational safety reasons, it is not permitted to install the pump with the motor facing downwards. A maintenance-free mechanical seal is used for shaft sealing. It is independent of the direction of rotation and made from wear-resistant silicon carbide (SiC). For the versions with the Seal-Guard-System, a mechanical seal made from wear-resistant silicon carbide (SiC) is used for sealing on the pump side and a mechanical seal in the form of cast carbon/chromium molybdenum on the drive side. The intermediate casing is filled with Mobil SHC Cibus 46 with NSF H1 certification lubricating oil to lubricate and cool the mechanical seals. This enables short-term dry running. All motors are equipped with a special seal for splash-proofing on the pump side. A surface-cooled three-phase motor with squirrel cage corresponding to efficiency class IE2/IE3 powers the pump. The motor is cooled by the dissipation of heat from the cooling fins to the surrounding air. In the case of pumps of the herborner.d-pm model, the pump is driven by a synchronous motor with permanent excitation for frequency converter operation. Observe the enclosed operating manual. A medium-cooled heat exchanger motor is used for pumps of the herborner.d-c model. This returns a large proportion of the motor's waste heat back to the medium via an integrated cooling system through which the medium is guided. Observe the limit temperatures specified in section General data. 11

12 General information The exact motor data can be found on the motor name plate. Caution! Impermissible heating will damage the three-phase motor. Comply with the voltage tolerance of ± 10% according to DIN EN Dimensions, weights, performance data The measurements, installation dimensions and weight details can be found in section 5.2 Dimensions. The instruction documents and the name plate data specify the performance and connection data of the respective pump type. Performance verification of the pumps is carried out according to DIN EN ISO 9906 (Rotodynamic pumps - Hydraulic performance acceptance tests), Class General data Motor data for D/ D-C model Design IM B5/V1 Protection type IP 55 Speed 1500 (1800) rpm 3000 (3600) rpm Frequency 50 (60) Hz Connection 2.2 (2.6) kw 230 5/400 3 (460 3) V Connection 3.0 (3.6) kw 400 5/690 3 (460 5) V Insulation class EN F (155 C) Motor data for D-PM model Design IM B5/V1 Protection type IP 55 Speed 1500 rpm 3000 rpm Connection V Insulation class EN F (155 C) Customer-specific solutions may differ from this standard data. Media temperature range for: Lower limit temperature: - 5 C Upper limit temperature: + 60 C + 40 C (Explosion protection version) The design temperature for pumps of type herborner.d-c is 40 C. Caution! For pumps of type herborner.d-c, pumped media which is < 15 C leads to the condensate formation and thus to damage to the motor. Observe the inlet temperature of the pumped media of at least 15 C. Ambient temperature range for: Lower limit temperature: - 5 C Upper limit temperature: + 40 C Density and viscosity of the pumped medium: Density: max kg/m 3 Kinematic viscosity: max mm 2 /s Customer-specific solutions may differ from this standard data. 12

13 General information Power correction: Reduce the power according to the specifications of the motor manufacturer if motors are used at ambient temperatures > 40 C or at altitudes > 1000 m above sea level. To do this, please contact the pump manufacturer. A differing density or viscosity alters the hydraulic performance of the pump. Observe the motor performance during this. Sound pressure level: The sound pressure level db(a) of the pump during cavitation-free operation lies within the range of Q optimum below the limit values specified in EC Machinery Directive 2006/42/EC. You can find information about the sound pressure level of the various motor models in Section 5.3 Technical specifications. 13

46 Installation/fitting 5.4 Electrical connection The electrical connection should only be carried out by a qualified electrician. In the case of PM motors, observe the operating manual included in delivery! Warning! Electric current can result in fatal injury. Provide equipotential bonding between the pump casing and the building earth. 5.5 Motor protection Warning! An incorrect electrical connection can result in fatal injury. Carry out connection work according to DIN VDE 0100; also comply with DIN VDE 0165 in potentially explosive atmospheres. The earth, neutral connection, residual current circuit breaker, etc. must - correspond to the directives of the local public utility company (PUC) and - function flawlessly according to the electrician's inspection. Use a motor circuit breaker or adequate motor protection with a tripping characteristic according to DIN VDE Install the integrated temperature monitors (e.g. PTC thermistors) in the motor control circuits so that the motor is switched off if the temperature monitor responds. The motor circuit breaker should be - regulated for nominal motor current during direct starting, - introduced into the delta link for star-delta starting and set to a maximum of 0.58-times the nominal current. Motors have a PTC thermistor as standard (see section PTC thermistor connection ). The cross-section and voltage drop of the supply line must comply with the respective regulations. Caution! Impermissible heating will damage the three-phase motor. Comply with the voltage tolerance of ± 10% according to DIN EN Warning! If the installed winding protection trips, it can result in a potentially fatal explosive atmosphere. Do not reactivate the system without first checking it and eliminating the cause of the disturbance. 46

47 Installation/fitting 5.6 Direction of rotation check Make sure you check the direction of rotation during the initial commissioning procedure and also at each new installation location of three-phase pumps. An incorrect direction of rotation will result in decreased pump power output, and may damage the pump. It is possible to activate/deactivate the pump temporarily (without explosion protection) without the risk of dry running. A start up procedure at approximately 5 Hz is advisable for operation with frequency converters. Each pump is to be inspected individually for control systems with multiple pumps. Danger! The rotating impeller can cut or crush people's hands and arms. Secure the pump when checking the direction of rotation. Do not reach into the pressure flanges or the intake port of the pump casing. The direction of rotation must be as shown by the rotation indicator arrow on the pump name plate. This must rotate clockwise when facing the motor fan. For pumps of the herborner.f-c model, check the direction of rotation using the duty point. Danger! Risk of a potentially fatal explosion during the installation phase. Provide a constant supply of pumped media to the supply and pressure pipes as well as to the interior of the pump that is in contact with the liquid. Provide appropriate monitoring measures to ensure this. Only then should you check the direction of rotation. Caution! Dry running the pump will destroy the mechanical seal! After starting up the pump, switch it off again immediately Changes in direction of rotation The direction of rotation can be changed by swapping two phases of the motor cable. 5.7 Motor connection diagrams Caution! An incorrect electrical circuit arrangement will result in breakdown of the three-phase motor. Observe the circuit arrangement. 47

Pay attention to the documents accompanying the motor and the information in the terminal box cover. Frequency converters can also be connected in a direct mounting configuration for pumps of the herborner.d and herborner.d-pm models up to 26.4 kw (only wall mounting configuration for herborner.d-c models). Possible frequency regulation of pumps is possible depending on the operating conditions. 48

49 Installation/fitting Model Motor Zone D/ D-C 50 Hz Hz 60 Hz Hz D-PM 1500 rpm rpm 3000 rpm rpm Pressure pipe - lay frost-free, - secure and - connect so they are stress-free. Pipe forces and moments must not affect the pump. Customer-specific solutions may differ from this standard data. Frequency converters must comply with the EU low voltage and EMC directives. With three-phase current frequency converters, use only an RCD (residual-current-operated protective device) of type B (AC/DC sensitive) for additional protection on the network side. Install a... - gate valve immediately upstream of the pump to close off the pipes. This makes it possible to remove the pump when the pipes are full. - non-return valve between the pressure flange and the gate valve. This prevents the pumped medium from flowing back after shutting off the pump and also prevents surges. Avoid bends directly in front of and behind the pump. You can obtain further information on the correct pipeline construction from the manufacturer. 5.9 ETS X4 An existing ETS X4 (electronic dry running protection system) that uses a vibrating fork sensor prevents dry running of the mechanical seal. For the mounting and electrical connection of the optionally available ETS X4, see the included operating manual Frost protection Notice! The effects of frost can damage the pump when full. Drain pumps during prolonged periods of inactivity Laying the pipelines Lay the pressure pipes in accordance with the applicable regulations and relevant accident prevention regulations. Warning! Escaping hot pumped media is potentially fatal. Do not exceed the pipeline forces. Ensure measures are in place for complete ventilation during the laying procedure. Caution! Escaping pumped media can cause burns to hands and arms. Depressurise the pump casing. Only then should you drain the pump. On pumps of the herborner.d-c model - see section Draining the herborner.d-c pump for draining, - fix the cooling hoses as instructed in section Cooling hose assembly on the herborner.d-c pump prior to recommissioning. 49

50 Commissioning 6 Commissioning Inspect the pump before commissioning and carry out a functional check. When doing this, pay special attention to the following: - Turn the motor shaft several times by hand. - Never allow the pump to run dry. - Have the pump and all the pipelines been properly connected? - Has the electrical connection been carried out in accordance with the applicable regulations? - Is the temperature monitor connected? - Is the motor circuit breaker set correctly? - Is the lubricant filling in the Seal-Guard- System (if present) visible and sufficient in the sight glass? - Is the ETS X4 connected (if available)? - Is the pump's direction of rotation also correct when it is operated via an emergency generator? - Are the gate valves that are required for operation open? - Is the pump mounted securely? - Are the inlets and outlets of the pumping station secure, and have they been inspected? Caution! A hot pump casing and hot casing cover can burn hands and arms. Do not touch pumps that deliver hot water. Take precautionary measures to prevent burning. Caution! Dry running the pump will destroy the mechanical seal! Before starting the pump, fill it and the supply pipe with the pumped medium. Then, de-aerate. Danger! Air bubbles or accumulations of gas around the mechanical seal create a potentially fatal explosive atmosphere. Provide a constant supply of pumped media to the supply and pressure pipes as well as to the interior of the pump that is in contact with the liquid. Provide appropriate monitoring measures to ensure this. On pumps of the herborner.d-c model, check the flow in the supply and return lines after de-aerating during commissioning. Alternately operate installed reserve pumps using the controller. This ensures the operational readiness of the pumps. 50

51 Commissioning 6.1 Operating modes and connecting frequency All models are designed for operating mode S1 (continuous operation) with a filled pump. Notice! Prolonged operation against closed gate valves heats up the pumped medium and the pump. Open the gate valves before operation. 6.2 Starting up To start the pump: 1. Close the gate valves and shut-off cocks of the manometer 2. Switch on the motor 3. Open the shut-off cocks of the manometer. Only open the gate valves slightly if the pressure pipe is empty. If the pipe is full, open until the permissible motor load is reached (compare the ammeter display with the details on the motor name plate!). Danger! Operating the pump with closed shutoff valves creates a potentially fatal and explosive atmosphere. Open the gate valves before operation. Use a motor circuit breaker or appropriate motor protection with a tripping characteristic according to DIN VDE Do not exceed ten starting procedures per hour. This prevents a sharp increase in temperature in the motor and an excessive load on the pump, motor, seals and bearings. Contact the respective manufacturer with regard to the permissible frequency of starting for possible starter devices. 51

52 Maintenance/cleaning 7 Maintenance/Cleaning Maintenance and cleaning work should only be carried out by specialist personnel. These personnel must be provided with personal protective equipment (e.g. protective gloves). Notice! Pumped media can be hazardous to people's health. Always wear personal protective equipment such as protective gloves and goggles. According to EN , a person is understood to be a specialist if they - are able to use their professional training, knowledge and experience as well as knowledge of the relevant standards to assess the work they have been tasked with and - are also able to identify any potential dangers. The pump is subject to vibrations during operation that can loosen the screw and clamp connections. Inspect the pump at regular intervals for any loose connections (recommendation is every 6 months for single-shift operation). Remove any dust deposits and impurities on a regular basis. Before maintenance and cleaning work, you must observe section 3.5 Shut-off procedures. Only use appliances and tools that are expressly intended for this work. Clean and maintain the pump at regular intervals. This will ensure trouble-free operation of the pump. Caution! Injuries may be caused when maintaining and cleaning the pump. Observe the safety regulations and the generally recognised codes of practice. Danger! The rotating impeller can cut or crush people's hands and arms. Allow the impeller to come to a complete standstill. Secure the pump to prevent it from rolling and tipping over. 7.1 Maintenance When carrying out maintenance and repair work, watch out for: - crushing hazards and - dangers due to electric current. Decontaminate the pump after pumping any media that are hazardous to health. Only authorised workshops/people are allowed to work on explosion-proof pumps while using original manufacturer parts. Otherwise, the explosion protection certificate will be rendered invalid. 52

53 Maintenance/cleaning Danger! Flying sparks may cause a potentially fatal explosion. Before dismantling the pump in potentially explosive atmospheres, make sure that the structure is adequately aerated. If the pump has been dismantled, carry out extensive repair and maintenance work at a separate location. Caution! Insufficient rotary motion of the motor shaft leads to the impeller jamming and to a failure of the mechanical seal. To counteract this, rotate the motor shaft several times by hand at weekly intervals. In addition, the following label can be found on the motor: Warning! When removing the pump from the pipe network, there is a risk of tipping which can result in serious injury. Secure the pump during transportation using appropriate separate lifting accessories. Only set down the pump on a sufficiently sturdy surface that is level in all directions. Also secure it to prevent it from tipping over. Figure 6 Dry running label Collect any waste and emissions in appropriate containers and dispose of them properly. The label tells you that the motor shaft should be turned several times by hand at weekly intervals and that the operating instructions should be observed! Follow the instructions on the label. 7.2 Maintenance instructions during prolonged periods of inactivity Protect the pumps from exposure to the weather (UV rays, sunlight, high humidity levels, frost, etc.). The points in section 6 Commissioning must be fulfilled before recommissioning the pumps. Danger! A failure of the mechanical seal can create a potentially fatal explosive atmosphere. Ensure proper functioning of the mechanical seal by monitoring it regularly. 53

54 Maintenance/cleaning For pump controllers, it is recommended to programme automatic activation/deactivation every 48 hours. A start up procedure at approximately 5 Hz is advisable for operation with frequency converters. 7.3 Anti-friction bearing lubrication Different guidelines need to be followed when lubricating or possibly relubricating the anti-friction bearing depending on the motor manufacturer, type and power. Danger! Insufficient lubrication of the anti-friction bearings in the explosion protection zone can result in a potentially fatal explosive atmosphere. Exchange anti-friction bearings that are subjected to a speed of 1500 (1800) rpm after every 20,000 hours of operation and after every 10,000 hours of operation if they are are subjected to a speed of 3000 (3600) rpm Anti-friction bearing service life Anti-friction bearings are supplied pre-lubricated. Danger! High magnetic forces during the disassembly and assembly of PM motors can lead to severe personal injury and property damage. Before disassembly and assembly, see Section 9 Disassembly/Assembly. Observe the enclosed operating manual Relubrication unit Depending on the motor manufacturer a relubrication unit is available on the motors operating at 1500 (1800) rpm - from 1.1 kw for both anti-friction bearings or - from 1.1 kw for the anti-friction bearing on the drive side and from 7.5 kw for both anti-friction bearings. A relubrication unit is not intended for motors with 3000 (3600) rpm. The following label is found on the motor if a relubrication unit is present: Notice! Anti-friction bearings that are used at a speed of (1800) rpm after 20,000 hours of operation (3600) rpm are to be re-lubricated or replaced, if necessary, after 10,000 hours of operation or every 3 years at the latest. Figure 7 Relubrication label The label points out that the operating manual should be followed and names the manufacturer of the grease being used. 54

56 Maintenance/cleaning Danger! A failure of the mechanical seal can create a potentially fatal explosive atmosphere. Ensure proper functioning of the mechanical seal by monitoring it regularly. Before decommissioning and storing the pump after a prolonged period of operation, flush it thoroughly with clear water and then clean it carefully. Hardened dirt deposits, limescale etc. can block the impeller and the motor shaft. When cleaning centrifugal pumps that are used in the food industry or in the supply of drinking water, use an appropriate disinfectant or cleaning agent. When using a Seal-Guard-System, regularly check for the correct level of the lubricant filling and contents (Mobil SHC Cibus 46 with NSF H1-approval). If the medium penetrates the mechanical seal, the seal must be replaced. Danger! The rotating impeller can cut or crush people's hands and arms. Observe section 3.5 Shut-off procedures. If monitoring units are installed for the mechanical seal, check their function. Danger! Leaky static seals can create a potentially fatal explosive atmosphere. Check the leak tightness of seals at regular intervals. Danger! Impermissible heating of the threephase motor can create a potentially fatal explosive atmosphere. It is imperative that the motor is kept clean. This will ensure adequate aeration. 7.6 Tightening torques for nuts and bolts 7.5 Cleaning Remove any sediment deposits when disassembling or dismantling the pump using mechanical means if necessary.
