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

I have a long asphalt driveway that I have been sealing with the asphalt sealer from Lowes and Home Depot. I thin the sealer with 25%-50% water depending on the brand of sealer, and spray with a soap nozzle on a pressure washer wand. Too thin and it dribbles a bit, too thick and it splatters, but this pump has been very reliable. With all the trial and error, this pump has been the most consistent part of the project. Doesn't use too much air. Not too loud. Sometimes when I stop the spray, the pump bleeds air so I added a ball valve to the air inlet.

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

Received pump tried to use wouldn’t work found misplaced o-ring replaced o- ring seems to work fine.

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

For a small pump it works very well. I pumped tire ballast out of 2 tractor tires , and refilled 1 tire , it did it with ease. I was very happy ,for an inexpensive pump it worked great.

This thing pumps oil quick.

Perfect! couldnt ask for a quicker, more efficient pump! Would defiantly purchase and recommend someone to buy!

so far so good 25 gal of hyd fluid fairly fast

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

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.

Recomendo

la pompa è arrivata, devo ancora installarla, ma la qualità dei materiali, al momento sembra ottima
