Worked very well.

Worst pump I’ve ever used.
Worked for water barely and then when I tried oil it didn’t work at all. Went out and spent 2k on a wilden pump and have had not a single problem. Kept getting air locked. Waisted time and money on this piece of crap. Go buy name brand and save yourself the headache.

Fast and Furious littke pumo!
Well at first we THOUGHT the unit failed . It did not,there was an air flow issue and we did not notice it. They sent out a replacement ASAP.We discovered the problem was our own doing, so I promptly returned the new one instead of swapping .This pump is fast, and furious. It does more than the old twice it’s size unit we had and is amazing.We use it for hydraulic fluid exchanges in the field.Old out , new in.It’s great!!

Worked Well Until
This pump worked well for us. We pump some fairly thick polymers and we use a portable gas powered compressor. It pumps about 10 gallons a minute of the really thick stuff (like Elmer's Glue) and about double that rate with the thinner stuff. Also, my air drier failed and damaged the pump. After much research I found that the air side rebuild kit is ARO 637434 Air Section Service Kit and available on Amazon. If for any reason this kit does not work as expected I will update this review.

Poor workmanship
New the pump leaked air from a gasket between two metal surfaces. I sent a message with a picture indicating where the leak was. The company has a no return policy. They suggested using Teflon tape to stop the leak. They either didn't understand were the leak was coming from or they are clueless about their product. The company offered a $30 refund. The product cost over $200. Not much compensation. I would not recommend purchasing any products from this company.

happybuy Diaphragm pump 1/2 inch inlet and outlet.
The pump works great and fantastic but was unable to pump our product due to the product viscosity. So I decided to exchange it for a more powerful pump. smooth transaction and reliable seller.
