Vessels
Pressure vessels and expansion vessels play a big role in keeping systems safe and balanced. Expansion vessels are commonly used in heating and hot water setups, where they absorb the natural rise in water volume as it heats. This keeps pressure under control, reduces the chance of leaks, and protects boilers, pumps, and pipework from damage.
Pressure vessels are found in pressurised water systems, including potable water supplies. By storing water under pressure, they cut down on pump cycling, extend system life, and deliver a steadier, more reliable flow.
At Pumpify, you’ll find both pressure and expansion vessels in a variety of sizes and specifications, so it’s simple to choose the right fit for your project.
