Features:
1. A-20 diaphragm pump doesn't spark.
A-20 is not in need of electric power to drive and prevents from electrostatic spark after grounding.
2. Not overheating
The compressed air powers the pump. When exhausting gas out, it inflates and absorbs heat, so temperature reduces and noxious gas is exhausted out when the pump works.
3.Suitable for liquids with particles
As it works by positive displacement type and there is a inlet ball valve, it is unblocked easily.
4.Hard to cut materials
When the pump works, materials are sucked in the same way to exhaust them out, so they are cut easily. A-20 is suitable for pumping unstable materials;
5.Fluid flow is adjustable.
A throttle is set in the fluid outlet to control fluid flow.
