The VAREM Intervarem S2H20361CS0BP000 is a 20 litre horizontal diaphragm pressure vessel for booster sets and domestic water systems. It absorbs pressure fluctuations and provides a buffer volume. This reduces pump cycling and limits wear on the motor and pressure switch.
The steel tank has a red paint finish and a carbon steel flange with a 1" male connection. The membrane is replaceable, so the vessel does not need to be replaced in full if the membrane fails. A central pump bracket allows a centrifugal or self-priming pump to be mounted directly on the vessel, forming a compact booster set.
The vessel is supplied with a pre-charge of 1.5 bar and is rated for a maximum working pressure of 10 bar at water temperatures from -10 °C to +99 °C. Dimensions are Ø 274 × 497 mm.
