How do high-pressure vortex pumps achieve high-temperature feed water (up to 100°C)?
Thread Content
Typically, high-pressure vortex pumps can only be used to supply water to boilers at temperatures below 60°C. However, when the condensed steam water from boilers is directly fed into the high-pressure feed water pumps, the service life of these pumps is significantly reduced and their failure rate increases greatly. I would appreciate it if experts could advise me on how to enable these pumps to handle high-temperature water (up to 100°C) without a significant decline in their performance or service life ?

Boiler make-up water is generally added at a pressure higher than that inside the boiler. At the same time, in order to avoid wasting the heat contained in the steam exhaust water, some boilers add this exhaust water directly to the water tank, from where it is pumped into the boiler for use as feed water. The temperature of this water is usually around 100 degrees.
