VEVOR Air Operated Double Diaphragm Pump, 44GPM, Max 115PSI Air Waste Oil Pneumatic Transfer Pump with 2 Extra Diaphragms, 1-1/2 inch Inlet & Outlet Aluminum Alloy Diaphragm Pump for Diesel Grease Oil

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.

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.

Works good needs a pre filter for pumping used waste oil

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

Works great so far for pumping used oil into holding tanks.
