Cavitation is the main reason for pump system breakdowns – and the high temperatures in steam boiler systems increase the risk of it occurring.

Avoiding cavitation requires considerations of the pressure available at the inlet of the pump in order to make sure that NPSHA > NPSHR.

Steam, water, oil?

Depending on the heating demand, boilers are divided into three main groups. One being steam boilers which are used because of the high latent energy content. Learn more on this as well as thermal oil boilers and hot water boilers.

The benefits of leaving out control valves

No pressure loss across the feed valve, boiler feeding adjusted according to steam consumption and energy savings on pump operation:

The benefits from controlling the level in the boiler directly with variable speed pumps are far from insignificant. In fact, the money saved equals the price of an expensive feed valve plus its maintenance costs.
