Fully packaged pressure booster set consisting of:
1 MHIE non self-priming horizontal stainless steel high pressure centrifugal pumps with integrated frequency converter that enables variable speed control. 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 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.
Control modes
Mode 1: Manual speed control via potentiometer
Mode 2: Pressure control via 4-20 mA or 0-10 V sensor signal, setpoint adjustment with potentiometer or via external 0-10 V or 0-20 mA signal (Factory Setting)
Mode 3: Speed control via external 0- 20 mA or 0-10 V signal
Short-circuit-proof +24 V voltage output with max. contact strength of 30 mA present on the electronic module. The module has potential-free contacts for SSM, red and green LED for ON/OFF signal.
All mounted on a common zinc plated steel base frame with anti-vibration mounts.
