Customer Reviews for VEVOR Air-Operated Double Diaphragm Pump, 2 inch Inlet & Outlet, Aluminum Alloy Body, 75 GPM & Max 120PSI, Nitrile Diaphragm Transfer Pump for Petroleum, Diesel, Oil and Low Viscosity Fluids

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.

I use a lot of these type pumps over the years. I’m very pleased with these at this price range.

The product came very fast and works like we needed it to.

flow rate is true, this pump is being used in a pipeline application and competes with $3,000.00 Ingersoll Rand ARO double diaphragms. I will be purchasing more of these. unfortunately the site says my pictures are not compatible but I have tons.
