Works great for the application we are using it for. It's a strong pump and fits perfectly to the tank we mounted it to.
Jennifer Jennifer
It pumps cold used oil well enough
For the money this pump does the trick at moving used oils. It has the ability to move some of the trash that collects on the bottom of the tanks but slows it's cycling when it's really thick and gross. My unit has a smallish leak on one side of the output leg and the bolts are tight. Not sure what the deal is there. I've used it about 8x now and have moved about 375gallons of varied used oils. One batch has a lot of debris in the tank and was the main purpose for buying this unit. Be nice if the manual was a little clearer on English.

Decent pump, great price
We use these to pump acrylic coatings (paint with sand in it) and they work great. Put a small air regulator right at the pump so you can easily control pump output, and make sure that all the pump bolts are tight before you use it. No problems.

1st time ordering and the process what quick, simple and we received our pump in 2 days with FREE Shipping. They also applied a coupon to the order!!!

Our facility was using Yamada AOD pumps that required rebuild every 6-12 months, for the price and time for a rebuild this is a more cost effective route. I just replaced the unit I ordered in Sept 2022, a 9 month life on a pump that cycles every 10 seconds and runs 20 hours every day is good value for our business.
