Description
Lowara GHV20/e-HM Series two pump Variable Speed Booster Sets
GHV20/e-HM series booster sets are variable speed pumping stations with two e-HM series Horizontal multistage pumps. Each pump is equipped with an HYDROVAR® frequency converter. This means that both pumps are capable of variable speed operation.
This type of system improves the comfort of the end user, reducing noise emissions. Thanks to the gradual switching off of the pumps “water hammer” is also reduced.
The Variable speed Horizontal multistage pump are made of AISI 304 Stainless Steel, discharge and suction manifolds are arranged at the rear of the unit.
All GHV20/e-HM sets include 2no 24 litre pressure vessel supplied loose. Vessels are 8,10 or 16 bar rated in order to cover the closed valve pump pressure.
Prices include for volt free contacts to be wired from the Hydrovar head back to the control panel.
Fill mode is standard on these sets to help reduce pipe stress on initial power up, after power failure or on reinstatement of low water condition.
