Grundfos Hydro Solo E CRE5-20 Three Phase Automatic Variable Speed Multistage Pump System Features: Grundfos variable speed motor, Discharge pressure transducer, Lockable main isolator, Run and Fault lights on the pump, Stainless steel base, Stainless steel manifold with pump isolation valve, 2-year warranty on the pump and motor, 5-year warranty on the pressure tank, Real electricity savings, Real dollar savings. Suitable Applications: water supply "on demand" (supplying faucets, showers, toilet cisterns, etc) irrigation systems with multiple blocks , irrigation systems with a varying flow demand, automatic car washing machines, automatic animal watering systems, multiple house or unit water pressure systems, office block water pressure system, multiple factory units with a variable demand, school toilet and shower blocks, water treatment systems, water filtration systems, factory pressure system with a variable demand, large homes, most other situations where a variable flow is required. Operation: When the system is installed a commissioned, the required operating pressure is set by the technician.   The pressure is continually monitored during operation via the "pressure transducer" located on the discharge manifold.   As the flow demand increases (more outlets turned on), the pressure transducer senses a slight drop in pressure and increases the speed of the pump so that it maintains the pressure at the higher flow rate.   As the Hydro Solo E system monitors the actual pressure extremely quickly and adjusts the speed of the pump accordingly, it is able to maintain a true "constant pressure" within the system.
