VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet/Outlet 30GPM Polypropylene Max 120PSI for Chemical and Industrial Use

These pumps are really dependable and very well priced. I have been using them for several years and have had nothing but good results.

I bought this to pump waste oil in my waist oil drum this pump is as good as $1000 pump. I would definitely recommend this one.

I only used it one time but it worked great

It seems not rugged enough. Stopped working when use the first day.

Worked just as it should. Could not ask for anything better.

Purchased this to move high-viscosity cable pulling lubracant (25,000–40,000 cP). Does the job well with 10' length on suction side out of 55gal container. Installed a couple of ball valves to control. Works with pancake compressor as well, but can move more with larger compressor.

Worked great for first week. By week two of pumping rusty water it quit working.

Works good needs a pre filter for pumping used waste oil

Looks great seems to be of good quality. Time will tell

Funziona perfettamente. Qualità prezzo ottima

Bonne qualité pour le moment Mais dommage de devoir tout démonter pour remettre de nouveaux joints … À la première utilisation, cela fuyait de partout….

The discerption clearly says 13.2 GPM. While in reality and on the pump it says 2.5 GPM. I bought this and shipped it to my company and when they tested it when it arrived they were very disappointed with how weak and slow it is. now i can't return it and i will eat the Cost. All i can do is warn people... I have picture and video of the pump Rate (Very Veeery Slow) This is FAKE information and this Seller should be banned from Amazon for Scamming people like this.
