Expansion Vessels / Membrane Pressure Vessels

Membrane pressure expansion vessels serve as a pressurised water reservoir and are suitable for temperatures up to 99°C.

 
Required for pressurised booster sets including water supply from wells and rainwater harvesting systems, membrane pressure vessels act as a buffer to minimize water hammering.

We keep stock of Zilmet Ultra-Pro pressure expansion vessels (horizontal & vertical) in the sizes 50 litres, 100 litres & 200 litres.
Larger vessels are available on request!

Reducing pump switching cycles to an acceptable level is a key factor to avoid premature wear & tear of the pump. 
Therefore, the correct size of vessel for a specific installation should be determined.
