Sizing Steam condesate return pump

[SAK9]

I have a heat exchanger which condenses steam at the rate of 300 kg/hr.What should be the flow rate for the condesate pump?Should it be also 300 kg/hr or higher with some margin.Some one advised me it should be twice ie 600 kg/hr due to higher condesation rate during startup

Generally the condensate pump is sized for twice the actual condensate flow so the pump can turn on and off. It also a matter of the size of the receiver and your actual start-up load that you should consider.

SAK,

Talk with the people at Spirax Sarco....

They have a lot of experience with these systems.

If you oversize the pump, it just works slower.....oversizing the pump also allows for future process changes and upgrades that somehow are always in the near future

SAK,
Do you want to use a centrifugal pump? 300 kg/h sounds like a case for a Ogden pump (it uses steam as pumping fluid) and you can get this from Spirax Sarco like MJC says (or Gestra, Amstrong etc.). Spirax Sarco has even something better than that a steam trap that works like a pump at the same time.

Kind regards
