ARO AIR OPERATED DIAPHRAGM PUMPS

Product Details:

AROAiroperateddiaphragm pumps:
Manufacturing Expertise andFusion of proven piston pump technology.
Air-operated diaphragm pumps can easily pump fluid from clean, light viscosity fluids to rough and corrosive viscous fluids, and can transport large particles without damage. It can also be used in explosion hazard areas thanks to the compressed air motor in the air operated diaphragm pump. The air-operated diaphragm pump can change the outlet and air pressure to pump from 1 liter per minute to a maximum of 1041 liters, and use an air filter, regulator and needle valve to deliver fluid pressures up to 125 psi (8.6 kg / sec) .
Performance of ARO diaphragm pumps:
The ARO diaphragm pump provides non-stopping and non-freezing functions.
Patented "Unstallable" unbalanced air valve design prevents stall problems with other pumps connected.
The "Quick-Dump" exhaust valve converts cold exhaust air from freezing parts to prevent freezing.
Based on our 5-year warranty, we have the most reliable product line on the market.
