## Description

desertcart.com: VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet Outlet Aluminum 35 GPM Max 120PSI, Nitrile Diaphragm, QBY4-25L-1inch-35 : Industrial & Scientific

Review: Good quality pump for the price. - These pumps are really dependable and very well priced. I have been using them for several years and have had nothing but good results.
Review: I built a sprayer for asphalt sealer - 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.
