About this item

  • Pneumatic diaphragm pumps have six advantages: 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.
  • It is easy to use, reliable in work, and 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 the pump, it will not be damaged. Once overloaded, the pump will automatically stop. Self-protection performance, when the load returns to normal, it can automatically start operation;
  • 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. Decrease performance gradually.
  • NOTE: This diaphragm pump can be used to pump chemical liquids, and the diaphragm used is PTFE acid and alkali corrosion resistant diaphragm. But because the pump is aluminum alloy, so it is best not to pump strong acid and alkali substances that will react with aluminum alloy.
  • NOTE: The pump can not be used when empty, there is no liquid inside for a long time when pumping will burst, such as the barrel inside the material is not available, empty, will lead to bursting; there is too much pressure, the diaphragm pump is the best air pressure is 4 kilograms, the maximum 6 kilograms, more than then the diaphragm pump will be damaged.

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.
