Fully packaged pressure booster set consisting of: 1 to 3 Helix V non self-priming horizontal stainless steel high pressure centrifugal pumps. Each pump has a 1/4 turn ball valve on suction and a 1/4 turn ball valve and a non return valve on discharge. The discharge manifold is equipped with an 8L diaphragm pressure vessel with through-flow fitting to DN 4807, pressure gauge, air vent. Low Pressure/Level Cut Out Pressure Switch (15-250mBar), optional on the suction manifold.
The Wilo-ElectronicControl starts the pump in automatic mode when the system pressure falls below the set pressure by more than the set pressure difference. Once the system pressure has reached the set pressure, the Wilo-ElectronicControl stops the pump after a time interval that has been previously set.
The Wilo ElectronicControl protects the pump against
– Dry run
– Excess current
– Excess water temperature
– Frost
– Short-circuit
– Overvoltage
– Undervoltage
All mounted on a galvanised base frame with anti-vibration mounts.
