Supply - Boosting. Watering - Irrigation. High pressure washing. Heating - Air conditioning. Water treatment. Incorporation into modular booster systems dedicated to building market. Pumped fluids : - Range 34 : clear, non- aggressive (drinking water, water glycol) - Range 316L : aggressive liquids (demineralized sea water, chlorinated water...) ADVANTAGES Reduction of mechanical and electrical constraints compared to a standard pump : - No more successive starts and stops, - flexible use, reduction of hammering and knocking, - limiting of starting current, - adjustment to installation by precise adjustment of speed and pressure. Reduction in sound levels by adapting pump speed to requirements. EVS Easy installation and use thanks to simple implementation and operation. Savings : - Optimization of complete product pump + motor + converter guaranteeing energy savings. - A single pump covers a full range of standard pumps. - One contact, one supplier for a complete automatic system. Safety: on a booster set, each pump is equipped with a frequency converter so that the function is still provided if one of the converters is faulty. MULTi-VE PN25 N.T. No 141-1/ENG. - Ed.3/5-8 1

Winding 3-phase : 4 V ± 1 %, 5 Hz 38 V ± 1 %, 6 Hz Frequency : 5 et 6 Hz Insulation class : 155 (F) Protection index : IP 54 CEM : EN OPERATION Electronic speed variation is applied to the asynchronous motors of the MULTI-VE centrifugal pumps. The goal is to regulate the speed of the AC motor by converting voltage and frequency of the mains inputs from 38 to 44 V ± 6% at 5 or 6 Hz into a three-phase voltage system with variable frequency and amplitude. The frequency converter then makes it possible to control the speed of the motor. This simultaneous action on the frequency and voltage is by means of two main elements : - a diode rectifier - a pulse width modulating inverter (MLI) Standard construction Range Stainless steel 34 SS 316L Main part 18/36/6 36/6 non-aggressive liquids Material aggressive liquids Sole fixing pump Cast iron EN GJL 25 Pump casing suction and discharge Cast iron EN GJL 25 SS 316L Motor support lantern Cast iron EN GJL 25 Impellers SS 34 SS 316L Cells (stage shell) SS 34 SS 316L Ext. liner tube SS 34 SS 316L Pump shaft SS 316 L SS 316L Intermediate bearing Tungsten carbide Mechanical seal Carbide Si/Carbon O-rings EPDM* Viton** Plugs SS 316L SS 316L * T 12 C **T 9 C The STAINLESS 316 L pumps are only available with NP 25 shells, round flanges. NB : Stainless steel 34 (X5CrNi18-1) or 316 L (X2CrNiMo ) recommended materials offering high resistance to corrosion. Clean conveyed liquids with fibers and containing little sand/ silica (max concentration 4 g/m3). The AC voltage conducted through the diode bridge is converted into a rectified DC voltage. At this stage, to refine the quality of the DC voltage at the rectifier output, a set of capacitors and coils eliminates any residual ripple output from the rectifier. In this way, we obtain a smooth DC voltage called the DC bus. With this development, the inverter definitively adjusts the voltage at the output of the variator to optimize the magnetizing of the motor. The set voltage at the inverter input is converted again into a variable voltage by acting as voltage pulses for a variable period of time via the transistors.

These transistors are controlled by the microcontroller which activates or deactivates them so as to vary the frequency at the variator output. The transistors (IGBT: Insulated Gate Bipolar Transistor) therefore operate by switching and act as switches to convert the DC voltage into a variable voltage. The IGBT switching activation frequency creates variable voltage and frequency magnitudes. The frequency must be high to eliminate the noise produce by magnetization.

3 OPERATION The pump must be controlled by either a - 1 V or 4-2 ma external signal. La principale application est l installation de The main application for these pumps, is to install them in parallel to form a booster controlled by a variable speed control unit. This booster range is called the ALTI-E. external Commande order externe signal signal : -1 : -1 V V or 4-2 ma ou 4-2 ma Régulateur Regulator Réglage Adjusting de of la the pression setpoint de pressure consigne -1 Signal V -1V signal Régulateur Regulator 4-2mA Capteur 4-2mA or -1V ou sensor -1V (pressure, (Pression, température, temperature, flow) débit...) Control laws The pump s speed is varied through an external signal according to the 2 laws below, which are dependent on this type of input (Voltage or current). In both cases, the pump will move along its own curve at between 4 and 1% of its speed in response to the external signal emitted. -1 V control -2 ma control The pump is not running The pump is not running Control in % Entrée Voltage en input tension (V) (V) Current Entrée en input courant (ma) (ma) 3

CONTROL Maintenance troubleshooting The frequency converter is equipped with fault analysis software allowing maintenance staff to perform a pre-diagnosis on the operation or non-operation of the pump. EVS When a fault appears, a counter starts and the number of faults is recorded. If the number of faults is less than 5, and if after 1 minutes no more faults have been detected, the number of faults recorded by the counter is reduced by 1 and the pump automatically restarts once the fault has disappeared. The pump automatically stops if this number is greater than 5 for 1 minutes. Analysis is based on parameters such as: - Motor temperature, converter temperature, over/under-intensity, power supply fault, short circuit, pump jammed, etc AUXILIARY CONTACT Centralized management The pump speed variation unit is equipped with a zero potential contact output relay intended for a centralized management interface. The relay is active when the pump is in operation or is able to operate. The relay is deactivated on a first fault or a mains power cut. It allows the control unit to be constantly informed of the pump s availability. relay relais active actif «Indicator» "report" "disponibilité" «Availability» relay relais at au rest repos 1 minutes glissantes Time Temps 4

5 PUMP PERFORMANCE ADVICE FOR CHOOSING A PUMP A pump is represented by a network of curves corresponding to different frequencies (Hz) and therefore to different motor rotation speeds. The frequency is expressed as a %. 5 Hm MULTI-VE Fréquence Min. frequency mini Fréquence Frequency = : 6% % Fréquence Frequency = : 7% % Fréquence Frequency = : 8% % Fréquence Frequency = : 9% % Fréquence Frequency = : 1% % An ESV pump is represented by a network of curves; all the curves between 1 and 6 are covered With speed variation, the power input is adapted to the Q / H need required, resulting in large energy savings. The NPSH of a MULTI-VE pump varies according to the curve on which it is placed. It is therefore important to know the desired pressure setpoint, especially for pumps used for suction on wells, and to take into account the pump s NPSH at maximum frequency, in other words 1 %. The maximum suction height for this type of pump must not exceed 1 metre. The benefits of speed variation are once again shown here by the yield, as the yield is optimum over a large flow rate range compared with a fixed speed pump Ql/min Ql/s kw 1, P. abs. hyd.,8,6,4,2, Qm3/h NPSH max.: maxi : fréquence frequency > > 1% % NPSH Qm3/h η% Qm3/h Efficiency rendement is optimised optimal sur over une a grande large range plage of de flows débit
