Review: Good pump - I installed this pump on an older herkules spray gun washer, to replace the worn out and obsolete graco pump. It was straightforward to hook up, and has survived permanently exposed to lacquer thinner without any issue. The only downside to the pump is the muffler on it is a joke, so it was really loud, so I replaced it with a fiber filled sintered bronze muffler, which remedied the issue.
Review: Meh, brevity not longevity - Did a great job while it worked. Got maybe a total of 150 hours out of it before it busted a seal and stopped working altogether. Difficult to disassemble. Disappointed it didn't last longer.

## Features

- Superior Quality and Performance: Pneumatic diaphragm pumps feature reliable quality, long service life, low noise, low vibration, never crashing, and fine workmanship. They can pump flowing liquids and transport some difficult-to-flow media.
- Easy Operation and Self-Protection: Easy to use and reliable in work, only needs to open and close the gas valve. Even if the pump runs without medium for a long time due to unexpected circumstances or suddenly stops, it will not be damaged. Once overloaded, the pump will automatically stop with self-protection performance, and when the load returns to normal, it can automatically start operation.
- Simple Maintenance Design: This diaphragm pump has simple structure, few wearing parts, convenient installation and maintenance. The medium conveyed by the pump will not touch the moving parts such as the valve, linkage, etc., unlike other types of pumps due to the wear of rotors, pistons, gears, blades and other parts.
- Chemical Compatibility Notice: This diaphragm pump can be used to pump chemical liquids, and the diaphragm used is PTFE acid and alkali corrosion resistant diaphragm. However, because the pump is aluminum alloy, it is best not to pump strong acid and alkali substances that will react with aluminum alloy.
- Operating Pressure Requirements: The pump cannot be used when empty, as running without liquid inside for a long time will cause bursting. The optimal air pressure is 4 kilograms with a maximum of 6 kilograms, exceeding this pressure will damage the diaphragm pump

### ⭐⭐⭐⭐⭐ Good pump
*by S***S on August 2, 2023*

I installed this pump on an older herkules spray gun washer, to replace the worn out and obsolete graco pump. It was straightforward to hook up, and has survived permanently exposed to lacquer thinner without any issue.

### ⭐⭐⭐ Meh, brevity not longevity
*by C***Y on November 7, 2025*

Did a great job while it worked. Got maybe a total of 150 hours out of it before it busted a seal and stopped working altogether. Difficult to disassemble. Disappointed it didn't last longer.

### ⭐⭐⭐ Half as good as I thought it would be
*by A***W on July 26, 2022*

I set this pump up for hydraulic oil. I had it sucking through a 48” hose (1/2” dia) and pushing through 35’ of 1/4” hose. The pressure and flow were unusable and the setup was a failure. I tried air pressures from 80 psi to 140 psi.
