4 General data SP A, SP Applications The SPA and SP pumps are suitable for the following applications: raw water supply irrigation systems groundwater lowering pressure boosting and industrial applications. Type key Example SP A B N Type range (SP A, SP) Nominal flow rate in m 3 /h Number of impellers First impeller with reduced diameter (A, B or C) Second impeller with reduced diameter (A, B or C) Stainless steel parts of material = DIN W.-Nr N = DIN W.-Nr R = DIN W.-Nr Pumped liquids Clean, thin, non-aggressive liquids without solid particles or fibres. The special SP A-N and SP-N versions made of stainless steel to DIN W.-Nr and SP A-R and SP-R versions made of stainless steel to DIN W.-Nr are available for applications involving aggressive liquids. Operating conditions Flow rate, Q:.1-28 m 3 /h. Head, H: maximum 67 m.

For MMS 1, 19 kw the temperature is 1 C lower. Operating pressure: Motor Grundfos MS 4" and 6" Grundfos MMS 6" to 12" rewindable Curve conditions The conditions below apply to the curves shown on pages 14-7: General Curve tolerances according to ISO 996, Annex A. The performance curves show pump performance at actual speed cf. standard motor range. The speed of the motors is approximately: 4" motors : n = 287 min -1 6" motors : n = 287 min -1 8" to 12" motors : n = 29 min -1 The measurements were made with airless water at a temperature of 2 C. The curves apply to a kinematic viscosity of 1 mm 2 /s (1 cst). When pumping liquids with a density higher than that of water, motors with correspondingly higher outputs must be used. The bold curves indicate the recommended performance range. The performance curves are inclusive of possible losses such as non-return valve loss. SP A curves Q/H: The curves are inclusive of valve and inlet losses at the actual speed. Power curve: P 2 shows pump power input at the actual speed for each individual pump size. Efficiency curve: Eta shows pump stage efficiency. SP curves Maximum operating pressure 6 MPa (6 bar) 2.5 MPa (25 bar) Q/H: The curves are inclusive of valve and inlet losses at the actual speed. Operation without non-return valve will increase the actual head at nominal performance by.5 to 1. m. NPSH: The curve is inclusive of suction interconnector and shows required inlet pressure. Power curve: P 2 shows pump power input at the actual speed of each individual pump size. Efficiency curve: Eta shows pump stage efficiency. 4

6 SP A, SP Features and benefits A wide pump range Grundfos offers submersible pumps with energy-efficient duty points ranging from 1 to 28 m 3 /h. The pump range consists of many pump sizes - and each pump size is available with an optional number of stages to match any duty point. High pump efficiency Often pump efficiency is a neglected factor compared to the price. However, the observant user will notice that price variations are without importance to water supply economics compared to the importance of pump and motor efficiencies. Example: When pumping 2 m 3 /h with a head of 1 m for a period of 1 years EURO 6, will be saved if a pump/ motor having a 1% higher efficiency is chosen and the price is EURO.1 per kwh. Material and pumped liquids Grundfos offers a complete range of pumps and motors which as a standard are made completely of stainless steel to DIN W.-Nr (AISI 34). This provides for good wear resistance and a reduced risk of corrosion when pumping ordinary cold water with a minor content of chloride. A pump range made of upgraded stainless steel is available for more aggressive liquids: SP N: DIN W.-Nr (AISI 316) SP R: DIN W.-Nr (AISI 94L) Alternatively, a complete range of zinc anodes for cathodic protection is available, see page 87. For example this may be advisable for sea water applications. For slightly polluted liquids containing for example oil, Grundfos offers a complete range (SP NE) in stainless steel to DIN W.-Nr (AISI 316) with all rubber parts made of FKM. Low installation costs Stainless steel means low weight facilitating the handling of pumps and resulting in low equipment costs and reduced installation and service time. In addition pumps will be as new after service due to the high wear resistance of stainless steel. Eta [%] A 5 Hz 3A 5A 8A 14A A , Q [m³/h] TM TM

7 SP A, SP Bearings with sand channels All bearings are water-lubricated and have a squared shape enabling sand particles, if any, to leave the pump together with the pumped liquid. TM Inlet strainer The inlet strainer prevents particles over a certain size from entering the pump. TM Non-return valve All pumps are equipped with a reliable non-return valve in the vale casing preventing back flow in connection with pump stoppage. Furthermore, the short closing time of the non-return valve means that the risk of destructive water hammer is reduced to a minimum. The valve casing is designed for optimum hydraulic properties, to minimize the pressure loss across the valve and thus contributes to the high efficiency of the pump. Valve flap TM Priming screw All Grundfos 4" pumps are fitted with a priming screw. Consequently, dry running is prevented, because the priming screw will make sure that pump bearings are always lubricated. Due to the semi-axial impellers of large SP pumps this priming is automatically provided. However, it applies to all pump types that if the water table is lowered to a level below the pump inlet neither pump nor motor will be protected against dry running. Stop ring The stop ring prevents damage to the pump during transport and in case of up-thrust in connection with start-up. The stop ring, which is designed as a thrust bearing, limits axial movements of the pump shaft. The stationary part of the stop ring (A) is secured in the upper chamber. The rotating part (B) is fitted above the split cone (C). A B C TM TM

9 Submersible motors SP A, SP Features and benefits MS motors A complete motor range Grundfos offers a complete submersible motor range in different voltages: Submersible motors, MS: 4" motors, single-phase up to 2.2 kw: 2 wire 3 wire PSC (permanent split capacitor) 4" motors, three-phase up to 7.5 kw 6" motors, three-phase from 5.5 kw to 3 kw Submersible rewindable motors, MMS: 6" motors, three-phase from 3.7 kw up to 37 kw 8" motors, three-phase from 22 kw up to 11 kw 1" motors, three-phase from 75 kw up to 19 kw 12" motors, three-phase from 147 kw up to 25 kw High motor efficiency Within the area of high motor efficiency Grundfos is a market leader. This is due to a newly developed motor concept which is introduced with the MS 4 and MS 6 motors. TM Rewindable motors The two pole Grundfos MMS submersible motors are all easily rewinded. The windings of the stator are made of a special water-proof wire of pure electrolytic copper sheathed with special non-hydroscopic thermoplastic material. The high dielectric strength properties of this material allow direct contact between the windings and the liquid for efficient cooling of the windings. MMS motors Industrial motors For heavy-duty applications Grundfos offers a complete motor range of industrial motors with up to 5% higher efficiency than that of Grundfos' standard motors. The industrial motors are available in sizes from 2.2 kw up to 22 kw. The cooling of the motor is very efficient due to the large motor surface. The efficient cooling makes it possible to increase the liquid temperature to 6 C at a flow of minimum.15 m/s past the motor.the industrial motors are for customers who value low operating costs and long life higher than price. Grundfos industrial motors are developed for difficult operating conditions. These motors will stand a higher thermal load than standard motors and thus have a longer life when subjected to high load. This applies whether the high load is caused by bad power supply, hot water, bad cooling conditions, high pump load etc. TM

10 Submersible motors SP A, SP Overtemperature protection Both for Grundfos MS and MMS submersible motors accessories for protection against overtemperature is available. When the temperature becomes too high, the protection device will cut-out and damage to the pump and motor be avoided. Restart of the motor after cut-out can be achieved in two ways: manual restart or automatic restart. Automatic restart means that the CU 3 attempts to restart the motor after 15 min. If the first attempt is not successful, restarting will be reattempted at 3-minute intervals. MS: The Grundfos MS submersible motors are available with a built-in Tempcon temperature transmitter for protection against overtemperature. By means of the transmitter it is possible to read out and/or monitor the motor temperature via an MTP 75 or a CU 3 control unit. The Grundfos MS 6 submersible motors can be fitted with a Pt1. The Pt1 is fitted in the motor and connected via a relay (EDM 35 or PR 222), which can be connected to the CU 3 control unit. MMS: For the protection of the Grundfos MMS submersible motors against overtemperature Grundfos offers the Pt1 temperature sensor as an optional extra. The Pt1 is fitted in the motor and connected via a relay (EDM 35 or PR 222), which can be connected to the CU 3 control unit. Example: MS 4 Protection against upthrust In case of a very small counter pressure in connection with start-up there is a risk that the entire pump body may rise. This is called upthrust. Upthrust may damage both pump and motor. Therefore both Grundfos pumps and motors are protected against upthrust as standard, preventing upthrust from occurring in the critical startup phase. The protection consists of either a built-in stop ring or hydraulic balancing. Built-in cooling chambers In all Grundfos MS submersible motors an efficient cooling is ensured by cooling chambers at the top and at the bottom of the motor, and by an internal circulation of motor liquid. See drawing in right column. As long as the required flow velocity past the motor is maintained (see "Operating conditions" page 4) cooling of the motor will be efficient. TM

11 Submersible motors SP A, SP Lightning protection The smallest Grundfos submersible motors, i.e. of the type MS 42, are all insulated in order to minimize the risk of motor burnout caused by stroke of lightning. Reduced risk of short-circuit The embedded stator winding in the Grundfos MS submersible motor is hermetically enclosed in stainless steel. The result is high mechanical stability and optimum cooling. Also, this eliminates the risk of shortcircuit of the windings caused by condensed water. Shaft seal MS 42 The shaft seal is of the lip seal type characterized by low friction against the rotor shaft. The choice of rubber offers good wear resistance, good elasticity and resistance to particles. The rubber material is approved for use in drinking water. MS 4, MS 6 The choice of material is ceramic/tungsten carbide providing optimum sealing, optimum wear resistance and long life. The spring loaded shaft seal is designed with a large surface and a sand shield. The result is a minimum exchange of pumped and motor liquids and no penetration of particles. MMS rewindable motors The standard shaft seal is a ceramic/carbon mechanical shaft seal. The shaft seal is replaceable. The material features good wear resistance and resistance to particles. Together with the shaft seal housing, the sand shield forms a labyrinth seal, which during normal operating conditions prevents penetration of sand particles into the shaft seal. On request, motors can be supplied with a SiC/SiC seal, according to DIN Example: MS 4 TM

Control parameters Function Problem Advantages Ground failure Temperature Overvoltage/ undervoltage Insulation resistance is measured only when motor is not operating. A high-impedance voltage is applied to the motor leads and leakage to ground is measured. If the factoryset value is higher than the one measured the motor cannot be started. MS The actual motor temperature is measured by means of the built-in Tempcon temperature transmitter and a signal is sent to CU 3 via the phaseleads. In CU 3 the measured temperature is compared with the factoryset value. MMS The actual motor temperature is measured by means of the Pt1. Via a relay, the signal is sent to the CU 3 where the measured temperature is compared with the factory-set value. Temperature protection requires a submersible motor with a Pt1. If the factory-set values are exceeded, a fault indication is given. If the CU 3 receives a temperature signal, the voltage is no longer monitored, but the motor will continue to run. Therefore, the motor and consequently the pump operation will be affected by voltage variations critical to the life of the motor. Damaged or decomposed insulation in motor, cable or cable joint. Overload, frequent starts/ stops, operation against blocked discharge pipe, insufficient flow velocity past the motor. The installation is close to a transformer, the mains do not absorb load variations. Possibility of failure indication on motor, cable and cable joint, service indication. Longer motor life, safe operating conditions, service indication. Important installation parameter, possibility of improving operating conditions. Overload Dry running Current unbalance Phase sequence If there is no temperature signal, the motor will be stopped in case of overvoltage/undervoltage. The motor power input is measured on each of the three phases. The registered power input is average of these three values. If the factoryset value is exceeded, the motor will stop. The motor power input is measured on each of the three phases. The registered power input is an average of these three values. If the average value is lower than the factorysetting value, the motor will stop. The power input of the motor is measured on each of the three phases. CU 3 and motor are installed so that the phase sequence corresponds to correct direction of rotation. CU 3 monitors changes in the phase sequences. Incorrect dimensioning of pump/motor, voltage supply failure, defective cable, blocking, wear or corrosion. Pump exposed to dry running or underload, for example caused by wear. Mains load is uneven, incipient motor defect, phase voltages diverging. Two phases are wrongly connected. Longer pump lift, safe operating conditions, service indication. Traditional dryrunning protection is no longer necessary, no extra cables. Motor protection against overload, service indication. Ensures correct pump performance. 77

78 Accessories SP A, SP Features and benefits Selecting the right pump The Grundfos CU 3 control unit and a flowmeter provide for a constant monitoring of energy consumption and performance of the pump thus making it possible to ensure that the right pump is selected for the application in question. The CU 3 control unit makes it possible to choose the borehole(s) to be in operation which offer(s) the lowest operating costs. Choosing the right time for service The constant monitoring by the CU 3 control unit makes it possible to service the pump, i.e. clean it and replace wear parts, at the best possible time. Today service and maintenance work is often carried out at regular intervals or when actual downtime occurs. Both are unlikely to result in an optimum energy-efficient operation. Operating costs kwh Time Time for service kwh Time TM Avoiding overpumping Using the Grundfos CU 3 control unit and a water level sensor it is possible to carry out test pumping of each borehole. This is done by measuring the water table level and the volume of water which is pumped. The purpose is to ensure that only the water naturally running to the borehole is pumped. As a result operations will provide for optimum efficiency. Consequently, the lives of both borehole and pump will increase, since both water aeration and the risk of ingress of aggressive water are reduced. Reducing costs of water treatment By minimizing the risk of overpumping and thus the pumping of impure ground water the costs of water treatment can be reduced to a minimum. Using the Grundfos CU 3 control unit and a sensor it is possible to measure water conductivity in each borehole. This provides for the possibility of selecting the borehole (or boreholes) to be in operation which supplies the best water quality at any time. Time Conductivity Time TM TM Sensor TM

85 Accessories SP A, SP MTP 75 motor protection Long motor life The MTP 75 protects against too high motor temperature. This is the most simple and the cheapest way of ensuring long motor life. The customer is certain that operating conditions are observed and is given indication of the time when a service check should be made. Too high motor temperature may be caused by: Overload Frequent starting/stopping (hunting) Operation against closed valve/frozen discharge pipe Insufficient flow of liquid past the motor Pumping of too hot water Deposits on the motor Overvoltage Undervoltage Current unbalance Dry running (Note that the pump is not protected if the water table is below the pump inlet. For example this may occur if several boreholes are located close to each other). Application and installation The MTP 75 can be used only for motors with built-in temperature transmitter and should be installed for instance in a control cabinet. The MTP 75 may be installed in any type of control cabinet containing a thermal relay with differential release and contactor. The thermal relay is necessary to protect against blocking or phase failure, since this will cause the temperature to rise much faster than the MTP 75 is able to register. The MTP 75 is supplied with base for mounting on DIN rail. Operation The temperature transmitter will send a high-frequency signal indicating the motor temperature through the motor supply cable. The MTP 75 will stop the motor via the contactor if the temperature rises above 75 C. The temperature limit is factory-set and cannot be changed. Display: No light: Motor stopped. No supply voltage or electrical fault at temperature measuring. Green light: Motor in operation and motor temperature OK, i.e. below 75 C. Red light: Motor stopped and motor temperature too high, i.e. above 75 C. The MTP 75 is reset manually by pressing the reset button on the front cover or by switching off the voltage supply to the MTP 75. No unnecessary downtime Since the MTP 75 measures only the temperature and no other parameters causing a temperature rise, the motor and thus the pump will stop only when the motor temperature is too high. Reliability The MTP 75 is reliable due to its simple construction and because it requires no extra cables in the borehole.

90 Energy consumption SP A, SP Energy consumption of submersible pumps The percentage distribution of service life costs occurring with a submersible pump for water supply is: 5% initial costs (pump) 85% operating costs / energy costs 1% maintenance costs. It is obvious that the highest savings can be achieved within energy consumption! The annual energy consumption, E, of a submersible pump can be calculated as follows: E = c x h x P 1 (EURO) c = specific energy price (EURO/kWh) h = operating hours/year (hours) P 1 = power input of the submersible pump (kw). Example: Calculation of the annual energy consumption of the submersible pump, type SP SP with MS 6, 3 kw, 3 x 4 V, 5 Hz. Duty point: Flow rate Q = 12 m 3 /h Total head H = 63 m Specific energy price c = EURO.1/kWh (consisting of day and night rate) Operating hours/year h = 32. Q H ρ P 1 = in kw 367 η pump η motor Q = m 3 /h H = m Density ρ = kg/dm 3 (assumed 1) 367 = conversion factor η motor = (example 84.5%, in equation.845) η pump = (not to be confused with the stage efficiency curve). By showing the P 2 /Q curve we make it easier for you to calculate the energy consumption. P P 2 1 = η motor P 2 = 26 kw (power requirement of SP pump at 12 m 3 /h, from curve P 2 / Q on page 59). Calculation of motor efficiency at duty point As standard the SP is equipped with a 3 kw MS 6 motor. At duty point (Q = 12 m 3 /h) the pump requires 26 kw, thus: a motor load of 87% (26 kw/3 kw) and a power reserve of 13%. From the table on page 72 the motor efficiency can be read as: 85% at a load of 75%. (η 75% ) 84% at a load of 1%.(η 1% ) The interpolated value in this example is η motor = 84.5%, η motor =.845. P 26 = = 3.77 kw E =.1 EURO/kWh x 32 h x 3.77 kw. The annual energy costs account to EURO If we compare the energy costs of this energy-efficient Grundfos submersible pump with a submersible pump, type SP 12-4, from 1995, (Q = 11 to 12 m 3 /h; H = 63 to 58 m; η motor = 82%), we see that at the same annual total flow of 384, m 3 and the same current price of.1 EURO/kWh, the annual energy consumption of the old pump amounts to EURO Wear and deposits on the motor and the pump were not taken into account. The pay-off time, A, (months) is calculated as follows: A Purchase price of energy efficient pump Energy savings/year = The purchase price of the energy-efficient pump is EURO A = ( ) 12 = 16.7 months The pay-off time is 16.7 months. Note: The complete system should be sized for energy efficiency (cable/discharge pipes). Cable sizing: In order to obtain an economical duty of the pump the voltage drop should be low. Today large water works already size cables for a maximum voltage drop of 1%). The hydraulic resistance in the discharge pipe should be as low as possible. 9

91 Cable sizing SP A, SP Cables Grundfos offers submersible drop cables for all applications: 3-core cable, 4-core cable, single leads. Cables for Grundfos 4" submersible motors are available with or without plugs. The submersible drop cable is chosen according to application and type of installation. Standard version: Max. liquid temperature +6 C. Hot water version: Max. liquid temperature +7 C, for short periods up to +9 C (For MS only). Tables indicating cable dimension in borehole The tables indicate the maximum length of drop cables in metres from motor starter to pump at direct-on-line starting at different cable dimensions. If star/delta starting is used the current will be reduced by 3 (I x.58), meaning that the cable length may be 3 longer (L x 1.73) than indicated in the tables. If for example the operating current is 1% lower than the full-load current, the cable must be 1% longer than indicated in the tables. The calculation of the cable length is based on a maximum voltage drop of 1% and 3% of the nominal voltage and a water temperature of maximum 3 C. In order to minimize operating losses the cable cross section may be increased compared to what is indicated in the tables. This is economical only if the borehole provides the necessary space, and if the operational time of the pump is long, especially if the operating voltage is below the rated voltage. The table values are calculated on the basis of the formula: Max. cable length of a single-phase submersible pump: L U U = I 2 1 cosϕ ρ -- + sinϕ X q L [ m] where U = Rated voltage [V] U = Voltage drop [%] I = Rated current of the motor [A] q = Cross-section of submersible drop cable [mm 2 ] X L = Inductive resistance:.78 x 1-3 [Ω/m] cosϕ = Power factor sinϕ = 1 cos 2 ϕ ρ = Specific resistance:.2 [Ω mm 2 /m] Example: Motor size: 3 kw, MMS 8 Rated current: 64.
