Constant Pressure Guaranteed DEMAND GRUNDFOS iSOLUTIONS

Perfect control for any pumps With a Control MPC you can combine great pumps with the perfect control of the CU 352. This means you not only get high efficiency pumps, but also control that ensures they are operated as optimally as possible. Control MPC 2- 6 pumps in parallel 0.37 – 75 kW* Available as: E: All pumps with integrated frequency converter EC: All pumps connected to CUE F: One pump connected to frequency converter S: All pumps fixed speed pumps *Larger systems available on request Tp/TPE 60Hz: From 0.37 kW to 315 kW - TPE up to 22 kW Capacities of up to more than 1250 m3/h Head up...

CONSTANT PRESSURE By continuously adapting the speed of the pumps to the flow demand, the required pressure is kept constant despite of fluctuations in flow. This ensures the consumer the highest comfort at any time of the day. Starting and stopping the speed controlled pumps are done in a matter that minimizes pressure surges and protects the piping. The days of water hammer are over. • The CU 352 offers perfect control over your pumps: • Constant pressure • Easy to operate • Monitoring • Communication • Energy Reduction • Optimized application functions The most advanced controller on the market...

SELECTED FUNCTIONS Proportional Pressure The flow demand in a typical installation is not static. It varies depending of the time of day, time of week ortime of year. Since the friction loss in the pipe system is dependent of the flow demand the required discharge pressure from the booster is not static either. h, = Head Loss due to friction, given f = friction factor (Darcy-Weisbach friction coffecient) discharge pressure to the flow demand the pressure can normally be lowered 18 - 20 hours each day while still delivering the required Money saved on energy since the pumps are operated at a lower...
