Fully packaged pressure booster set consisting of:
1 MHI non self-priming horizontal stainless steel high pressure centrifugal pumps with impellers/ diffusors, with a bi-directional mechanical seal and driven by a single phase motor. 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 switch.
The WRAS approved 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. 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.
Electro-mechanical Starter box for the automatic control of the booster set, consisting of:
motor contactor and overload unit, adjustable pump run on timer, hand/off/auto switch and reset pushbutton. Volt-free contacts for run and fault signals.
All mounted on a common powder coated steel base frame.
