VEVOR Air-Operated Double Diaphragm Pump, 1/2 in Inlet & Outlet, Polypropylene Body, 13.2 GPM & Max 120PSI, PTFE Diaphragm Pneumatic Transfer Pump for Petroleum, Diesel, Oil & Low Viscosity Fluids

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.

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.

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
