I have purchased multiples of these diagphram pumps. Great for mild acids and bases and waste water. We have had some in service for close to 2 years now with about 4 hours use per day without any hassles.

Great price, quality and lead time. We have purchased a second one of these diaphram pumps now and very happy with the performance.

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.

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.

Un buen servicio con productos accesibles a buen precio buena atención, recomendado para facilitar la nesecidad del cliente

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!!!

Easy to use and strong pumping power. only thing is that you need an air connection to the air supply and its some strange thread and I can't find anything that fits there. There is a 1/4" line that goes out that we could plug with a quick coupler to an home made coupler. Good product!

Very compact, very good equipment, good quality withstands industrial and continuous use. i recommend it.

Great pump for the price. Sometimes you have to take it apart and clean up the debris inside. Reassemble works fine. Some bolts were not tight but overall a great little unit.

Works great and pumps super fast. Had some troubles at first getting it to stay primed, but after taking it apart a couple of times it seems to be working fine now.
