7000 psi min, 28 gpm min variable displacement pumps
7000 psi min, 28 gpm min variable displacement pumps
(OP)
I am looking for additional manufacturers of variable displacement pumps with a 28 gpm min flow and greater than 7000 psi pressure rating. We are running endurance testing on high pressure valves are destroying pumps every 9 months or so. We have done what we can to the circuits to eliminate pressure spikes that feed back to the pump during cycling. The Parker/Denison pumps have failed quickly. Dynex pumps are lasting the 9 months. We are currently trying a Rexroth pump. I have spent a lot of time searching and have not found any suppliers with pumps capable of the 7000 psi pressure at a continuous duty cycle. Any suggestions would be appreciated.

At 28 gpm and 7000psi, what did you expect? Nothing lasts forever.
