Description
Booster Pump Set packaged on a stainless steel base supplied with pressure vessel and ancillary controls ready for installation. A separate cistern (tank) is required to supply the set. The set is approved for drinking (wholesome) water applications. The primary purpose is to boost the water pressure where the maintained mains supply pressure is less than 1 bar or where significant water storage is desired (e.g. 15 mins). The set may also be used for Fluid Category 5 backflow protection when supplied via a tank with a Type AB air gap. The standard unit BPELC1 is quiet by virtue of a variable speed centrifugal pump, anti-vibration rubber feet and flexible stainless braided connection hoses. The unit comes with a low level pump cut out, level controller. All sets are supplied with pump controls: inverter, pressure transducer and BMS. The set has the option of Dual Level Control (model LC2). The level control box provides additional solid state delayed action for cistern (tank) filling, via a solenoid controlled filling arm.
