Fully packaged pressure booster set consisting of:
1 MHIE non self-priming horizontal stainless steel high pressure centrifugal pumps with impellers/ diffusors, with a bi-directional mechanical seal and driven by a three phase motor with integrated frequency converter for variable speed control between 26 and max. 65 Hz.
Pressure setpoint adjustable by pump-integrated potentiometer or transducer. Automatic zero flow recognition and plant switch-off impulse. Integrated motor overload protection by electronic current monitoring. Run, fault and standby LEDs to indicate current operating conditions and volt-free contacts for remote fault signal. The pump has a 1/4 turn ball valve and a Non return valve on discharge. The discharge assembly is equipped with an 8 litre diaphragm pressure vessel with through-flow fitting to DN 4807, pressure gauge and pressure transducer.
The polypropylene break tank has an actual capacity of 150 litres and is complete with an AB type airgap to WRAS regulations 1999 and BSEN 13077, this is suitable for backflow prevention to Category 5 systems.
The water level is controlled via ½” BS1212 equilibrium ball float valve sized for a minimum of 1 bar inlet pressure. Low level protection to the pump is provided by side mounted float switch inside the tank. The tank can be drained via ½” drain cock.
The Weir and ¾” overflow are screened to enable installation on hygienic systems. All parts are compliant with Reg 4 which gives compliance to UK’s Water Supply Regulations of 1999.
This unit is not designed to supply Drinking water
All mounted on a common powder coated steel base frame.
