4 Quart Hydraulic Power Unit, Double Acting Dump Trailer Pump, 3200 PSI Max Relief Pressure & 0.91 GPM Flow Rate, DC 12V Hydraulic Pump with Metal Reservoir for Dump Trailer Car Lifting, Black

The performance is amazing, makes my job so much easier! We installed this in our single car trailer and does the work itself! I Highly recommend this product! I’ll post pictures soon !

I purchsaed this pump for a 12 foot tilt trailer that had a valve on the ram going port to port a manual setup. I read a lot of reviews and I was worried about a lot of people having problems with trying to find some non standard British fittings. It came in the box with 4 fittings. I removed the ones in the pump replaced them with the other provided. I made two hoses up for exact fit. Everything I used was power steering ram fittings. Welded a piece of flat bar 2"x3/8 8" long to the frame for mounting. I bolted the pre threaded pump block with M10-1.5x35MM to the welded flat bar. The the port coming out of the relay valve with the red knob on it is the pump (up) button and the other side of the block is the the (down). I adjusted the pump so it would not over pressure up or down, so it would bypass at a reasonable pressure. It lifted 2800Lbs with ease. The unit was properly prewired. All of the electrical stud contacts had to be torqued. Be carful the isolated relay contactor is a cheaper one but sufficient for the load. I Used two number 2 wire with no voltage drop at 3' long. Pump is fast. I installed some baffles on the hoses at A-B outputs to tame it down little. I dont think the solenoid and relays are water proof. If this thing will be exposed to weather I would build a cover over the pump electronics. I have only ran it 30-40 times to soon to tell if it will last. Good design well made product for the money. Unit came packaged good.

I have two of these things, and they worked fine for several months. But then they both started having motor issues, they barely run at all. I found that if I tap the motor housing with a hammer, they would sometimes wake up and run, but not always. So I took them both apart... and found the problem easily enough! That motor had that much moisture, corrosion, rust and dust in it, no wonder it wouldn't run. THESE MOTORS ARE NOT SEALED AT ALL!! The brushes were corroded tight so that they couldn't slide, the sides of the motor were rusty. So I got out the wire brush, brake cleaner, sand paper, and P'BLASTER. Took it all apart, cleaned it up, lubed it up, and re-assembled it. Put it back together with gasket maker between the motor housing sections to seal it up. They both run fine now, after 3 hours of work. This was basically a $200 crash course in electric motor repair. And I didn't even start talking about the stupid hydraulic fittings on the side of the pump. That's very frustrating when you are trying to install it and the local hydraulic shop can't even come up with the right thing. Check out all the other reviews that talk about that....! Hey, you get what you pay for!!! Why do we even buy from the Chinese!?

So far it seems to be working as advertised, will report back if anything changes.

Good pump !!!!

Worked perfect. Changed old cherrypicker ( used to lift items or in my case pull engines from vehicles ) from manual to hydraulic. Should have changed years ago

This pump is of high quality and seams to work as advertised!

The return valve clogs or malfunctions very quickly causing my dump body to be stuck in a raised condition, only way to get it down is to loosen the return hose and loose 2 quarts of HYdraulic fluid, - not very nice if you are at a job. They don’t accept returns and customer service is non-existent, wish I could or new who to call to get a replacement valve, I put a hydraulic filter on to make sure the fluid is clean, still binds up after a few uses, not happy, never had this problem before, this is new having this problem so don’t trust it. Very frustrating, other brands do not use this type of valve so this is a bad design.
