Seal/cooling liquid for liquid ring vacuum pump
Seal/cooling liquid for liquid ring vacuum pump
(OP)
Can any fluid be used for seal/cooling fluid in a liquid ring pump e.g. crude oil (gas a gas application)?

nearly any liquid is suitable but pls. check
- vapour pressure(s) (because of cavitation and because of a possible loss of capacity if a fraction is condensing during compression and reflashing at the inlet)
- viscosity (start conditions, power absorbed,..)
- specific heat (the highest the best, as the seal liquid will have to evacuate the heat)
- solubilty of gas in the seal liquid (possible re-flashing at inlet condition).
- pump and seals materials
