The VAREM Inoxvarem V2H20360S40BP000 is a 20 litre horizontal diaphragm pressure vessel in AISI 304 stainless steel. It is intended for booster sets, pressure boosting systems and domestic hot water installations. It absorbs pressure fluctuations and provides a buffer volume. This reduces pump cycling and limits wear on the motor and pressure switch. Its stainless steel construction and drinking-water-safe membrane make it suitable where water quality is critical.
The tank and flange are stainless steel, with a 1" male connection. The membrane is replaceable (spare membrane: MB020S7P00000000), so the vessel does not need to be replaced in full if the membrane fails. The pump bracket allows a centrifugal or self-priming pump to be mounted directly on the vessel.
The vessel is supplied with a pre-charge of 2 bar and is rated for a maximum working pressure of 8 bar at water temperatures from -10 °C to +99 °C. Dimensions are Ø 274 × 497 mm.
