Fully packaged pressure booster set consisting of:
1 MHIE non self-priming horizontal stainless steel high pressure centrifugal pumps with an integrated frequency converter enables variable speed with pressure control with pressure sensor, set point adjustment via green button or via external signals. The pump has a 1/4 turn ball valve on suction and a 1/2 turn ball valve and a non-return valve on discharge. The discharge manifold is equipped with an 8 litre diaphragm pressure vessel with through-flow fitting to DN 4807, pressure gauge, air vent and pressure sensor (4-20 mA). Level float switch (15-250mBar), installed inside the tank.
260 litre WRAS approved fibreglass tank with a removeable AB air gap lid, 3/4″ inlet equilibrium ball valve, overflow and drain connections.
Output:
•+ 24 V voltage output with max. contact strength of 50 mA
•Potential-free collective fault and run signals
•External On/Off mode. IR communication
•Plug-in position for Wilo IF-Modules Modbus, BACnet, CAN, PLR, LON for connection to the building automation
All mounted on a common zinc plated steel base frame with anti-vibration mounts.
