ABSTRACT:
A pump discharge assembly for a submergible pump installation, for use in an oil well and the like, has inlet ports for receiving liquid from a pump discharge, which ports are regulated by a back-pressure compensating valve. The valve obturates the ports upon start-up of the pump and prevents liquid being pumped unless or until the pump discharge pressure has attained a suitable level. The arrangement prevents excessive flow rate on start-up of the pump if the back-pressure is too low.
