Customer Reviews for VEVOR Air-Operated Double Diaphragm Pump, 1/2 in Inlet & Outlet, Cast Iron Body, 8.8 GPM & Max 120PSI, Nitrile Diaphragm Pneumatic Transfer Pump for Petroleum, Diesel, Oil & Low Viscosity Fluids

Awesome little pump. Works great. Use it for waste oil transfer. Best thing is the price. Quality is there but at this price when it fails get another

Made quick work transferring my waste oil.

Perfect for transferring waste oil. Not super speedy but gets the job done.

For years I purchased GRACO pumps at three times the price. Ordered my first 1/2 inch pump in January and everything is working great. "Dolly" in customer service has also helped with technical questions along the way. Highly recommend these pumps from Happybuy.

Works great for being off the grid. lots of power!!

Awesome

Great for pumping hydraulic fluid. Moves quick. No issues so far, but I've only had it about 6 weeks.

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!!

Order this due to the fact a friend had one and he raved about how great it was. Use it to pump our oil from barrels to our waste oil heater. Sure does a great job. Thank you.

Excelente todo les estaré comprando más cómo puedo ser sus distribuidores en Venezuela??
