Testing hydraulic pump


Recommended Posts

Having a 5hp hydraulic pump givin to me in trade for a little labor. It is pump and motor only. The guy bought it used as a working unit but has never used it. Is there an economical way to test the unit without buying valves and hoses? Most likely won't build a press if this unit is doa and would rather avoid buying parts that won't be used if pump is not good.

Probably the best way is to just take it to a hydraulic shop and get it put on a test bed then there is no risk of damaging the pump/motor/or your self this will incur a cost but if the unit was free its an investment in the future use. A more risky way is to eyeball the gears of the pump for any scoring or dents in the gears, DO NOT conect it up with out a relief valve and pressure gauge and have the relief backed out so you can work up to a pressure setting. The max pressure/ model serial number is usually on a lable or engraved on the pump body. Take it to a hydraulic place is the best bet Cheers Beaver
