Customer Reviews for VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet Outlet Aluminum 24 GPM Max 120PSI for Industrial Use

Seams to be a very good pump, we are using it to pump old oil from one container to another, seams to be working very well so far.

You can't beat it for the price & reliability. The pump do last quite a while. .

We use these to pump acrylic coatings (paint with sand in it) and they work great. Put a small air regulator right at the pump so you can easily control pump output, and make sure that all the pump bolts are tight before you use it. No problems.

Our facility was using Yamada AOD pumps that required rebuild every 6-12 months, for the price and time for a rebuild this is a more cost effective route. I just replaced the unit I ordered in Sept 2022, a 9 month life on a pump that cycles every 10 seconds and runs 20 hours every day is good value for our business.

flow rate is true, this pump is being used in a pipeline application and competes with $3,000.00 Ingersoll Rand ARO double diaphragms. I will be purchasing more of these. unfortunately the site says my pictures are not compatible but I have tons.

Works Good for our application of removing garnet from our water jet tank and would recommend this to anyone needed to pump garnet

I bought this in Feb. 2024 to pump waste oil. It worked well until April 2025 and quit working. I looked into repairing it but the cost for a replacement was good enough to justify just buying another one.

Absolutely great for the price! I have easily pumped over a 1000 gallons of diesel/oil/water mix with this pump so far and it is still working good. I will say it seems to need primed a lil more than the higher priced ones I have used and if your looking to continually run this for a long period of time your going to need a pretty good size air compressor, but it gets the job done!, and for the price I'm not going to complain!

Seems to work good, only issue I had is the air fitting is NOT 1/2" NPT like the listing says, I believe its 3/16" npt. Luckily I had a fitting to adapt it to 1/4"

Was good mounted it on a waste disposal tank for the shop . Would buy another one just for a spare .
