3 Product data CI, CIU Introduction The Grundfos CI pumps are non-self-priming, horizontal, multistage centrifugal pumps. CIU pumps are horizontal, multistage centrifugal pumps of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal. The pumps are made of stainless steel, and the bearings are lubricated by the pumped liquid. GR759 Pump and motor are integrated in a compact and userfriendly design fitted to a base plate making the pumps suitable for installation in compact systems. The pump is made of corrosion-resistant materials and thus ideally suited for water supply and a wide range of applications in industry, agriculture and in the food industry. CI pumps have many incorporated advantages such as those mentioned below. Worldwide usage Different certificates and approvals like UL/CSA for America and Canada. Different voltage and frequency combinations. State-of-the-art shaft seal materials (silicon carbide SiC-G) offering these benefits: - high wear resistance and long operating times - reduced risk of sticking if the liquid contains glycol - improved dry-running properties due to the graphite content of the SiC. Customized solutions See Lists of variants on page 36. Motor adaptation. Pump body modifications. GR531 - GRA115 CIU pumps have many incorporated advantages such as those mentioned below. Low noise level No noise from the fan due to the liquid-cooled motor means a very low noise level. Worldwide usage Different certificates and approvals like UL/CSA for America and Canada. Different voltage and frequency combinations. Customized solutions See Lists of variants on page 36. Pump body modifications. Modifications for R134a refrigerants. Applications The CI and CIU pumps are primarily designed for industrial applications. Typical applications CI CIU Water treatment Industrial washing and dish-washing machines Pressure boosting of process water eating and cooling in industrial processes Air-conditioning Air washing, moisturisation and humidification (softened water) Water supply and pressure boosting (potable water, also slightly chlorinated) Fertilizer/dosing systems Aquafarming In addition, the CI, CIU pump is suitable for many special applications.

4 Product data CI, CIU Pumped liquids CI, CIU pumps are suitable for thin, clean and nonexplosive liquids without solid particles or fibres. The pumps are able to pump liquids such as demineralised water, softened water, cleaning solutions and light oils. When pumping liquids with a density and/or viscosity higher than those of water, motors with correspondingly higher outputs must be used, if required.

WinCAPS can be used for the calculation of motor output when anti-freeze additives are used. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are chloride content, p value, temperature and content of solvents, oils. p [bar] Clean water 16 1 CI 15/CI BUBE/BUBV 8 BQQE/BQQV 4 BUBE BQQE Maximum operating pressure and temperatures The actual operating range depends on the operating pressure, the pump type, the type of shaft seal, the pumped liquid and the liquid temperature.

Furthermore, it is less sensitive to short-time dry running. Note: Dry running must always be avoided. TM Maximum operating pressure: 1 bar. Maximum inlet pressure is limited by the maximum operating pressure. Shaft seal Select the shaft seal on the basis of liquid temperature and type of liquid. For other liquids than water, the chemical resistance of the materials, including seal face, seat and rubber components of the shaft seal, must be taken into account. The following table shows the available shaft seal types. 4

The motors require no further motor protection. Note: Single-phase motors with UL approval (1 x 115/ 3 V, 6 z) do not have built-in motor protection and therefore require external motor protection. The three-phase motors do not incorporate thermal protection and therefore require external motor protection in accordance with local regulations. The sound pressure level of the pump is lower than the limiting values stated in the EC Council Directive 98/37/EC relating to machinery. Frequency converter operation Most three-phase motors can be operated with a frequency converter. See Lists of variants on page 36. Materials, CI Pos.

8 Product data CI, CIU Pump, CIU The lack of a mechanical seal offers opportunities like using the pump for liquids which must be pressurized to stay fluid, such as the coolant R134a. Please contact Grundfos. The pump is compact with small physical dimensions, axial suction port and radial discharge port. Connections CIU CIU 4 Axial suction port Rp 1 Rp 1¼ Radial discharge port Rp 1 Rp 1¼ Motor, CIU The motor is a -pole, asynchronous squirrel-cage motor. The motor is cooled by the pumped liquid, and no fan-cooler is therefore used which make the sound level very low. The pump is thus suitable for noise-sensitive places, for instance in dwellings. Standard voltages: 1 x -4 V, 5 z 3 x -4 V, 5 z 3 x V, 5 z 1 x 115/3 V, 6 z 3 x 8-3/44-48 V, 6 z 3 x 575 V, 6 z. Voltage tolerance: + 6 %/ 1 %. Electrical tolerances according to EN 634. Enclosure class: IP 44. Insulation class:. Sound-pressure level: 44 db(a). Single-phase and three-phase motors have overload protection. The pump requires an external contactor for motor protection, connected to the built-in thermal overload unit. The sound pressure level of the pump is lower than the limiting values stated in the EC Council Directive 98/37/EC relating to machinery. Materials, CIU Pos.

34 Pumped liquids CI, CIU Pumped liquids Thin, non-explosive liquids, not containing solid particles or fibres. The liquid must not chemically attack the pump materials. When pumping liquids with a density and/or viscosity higher than those of water, oversized motors must be used, if required. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, p value, temperature and content of chemicals and oils. Please note that aggressive liquids (for instance seawater and some acids) may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. List of pumped liquids A number of typical liquids are listed below. Other pump versions may be applicable, but those stated in the list are considered to be the best choices. The table is intended as a general guide only, and cannot replace actual testing of the pumped liquids and pump materials under specific working conditions. The list should, however, be applied with some caution as factors such as concentration of the pumped liquid, liquid temperature or pressure may affect the chemical resistance of a specific pump version. Safety precautions must be made when pumping dangerous liquids. Notes a b c d e f May contain additives or impurities which can cause shaft seal problems. The density and viscosity may differ from those of water. Consider this when calculating motor and pump performance. In order to avoid corrosion, the liquid must be free of oxygen. Flammable or combustible liquid. Safety precautions must be considered to ensure safe handling of flammable liquids. andling the liquid above the flashpoint and/or boiling point will require the greatest restrictions.

36 Variants CI, CIU Variants Lists of variants Although the Grundfos CI, CIU product range offers a number of pumps for different applications, customers require specific pump solutions to satisfy their needs. Below are the options available for customizing the CI, CIU. Contact Grundfos for further information or for requests other than the ones mentioned below. Motors Motor with thermal protection Oversize motor Dual-voltage motors 5/6 hz Use of external frequency converter arting plug Terminal box position Grundfos offers motors with built-in bimetallic thermal switches or temperature-controlled PTC sensors (thermistors) incorporated in the motor windings. In installations where one of the conditions mentioned below is present, the motor size must be evaluated to make sure there will be no risk of overload. Ambient temperatures above 4 C. Liquid temperatures below C. Installation at an altitude of more than 1 metres above sea level Use of glycol or other high-viscous liquids. Alternative motors are available on request. In some cases the standard product can run at dual voltage and frequency. If the standard product cannot be used for dual voltage, a bigger motor can very often be used instead. For most three-phase CI, CIU pumps a frequency converter can be used. Single-phase motors are not suitable for frequency converter operation. In many cases where an external frequency converter is used it is necessary to protect the motor against voltage peaks higher than 65 V (peak value). In these cases it is often less expensive to ask for phase insulation in the pump than use a filter such as an LC filter. Grundfos offers pumps with phase insulation to protect the pump against voltage peaks up to 1 V (peak values). This is a customized version, and the supplier of the frequency converter must be consulted. arting plugs are available for easier replacement of pumps. Other terminal box positions are possible. Certificates and nameplates Certificates Extra nameplate UR-marked motor Special tests or cleaning Silicone-free Grease-free Rinse in alcohol Pumps Low-temperature pump Product options Extra low noise level CI 15 and Pump colour Pumping of refrigerants Certificate of compliance with the order Test certificate Inspection certificate Standard test report If the UL-listed product according to UL778 is not available, a pump with URmarked motor according to UL14 can be offered as an alternative. Exposed to temperatures below C, coolant pumps may require neck rings with a different diameter or without neck ring in order to prevent impeller drag. If neck rings are removed a drop in head performance must be expected. In some extreme cases, 3 C cold liquids can be pumped by a CI. Contact Grundfos. Under the right conditions, it is possible to remove the ventilator fan and thus reduce the noise level. All colours are possible. The CIU is able to pump liquid gases, such as R134a. Shaft seals BUBV, BUBE, BQQE, BQQV are standard for CI, CIU pumps. Shaft seals with FFKM or FXM O-ring material are recommended for applications where the pumped liquid may damage the standard O- ring material. Connections and other variants Pipe connections TriClamp connection Electropolished pump sleeve NPT and Rp threads are available. TriClamp connections are of a hygienic design with a sanitary coupling for use in the pharmaceutical and food industry. To substantially reduce the risk of corrosion. For use in the pharmaceutical and food industry. 36
