The main advantages of the ARO pneumatic diaphragm pump are the key components of the pneumatic pump - the pneumatic motor, no dead point, no stall motor, d-type valve structure, etc. These patents guarantee the ARO pneumatic diaphragm pump in a high position in the motor technology.

Ingersoll rand /ARO pneumatic diaphragm pump provides zero dead point, zero freezing point operation. "No dead point" unbalanced valve design will not form a dead point when the pump stops, to avoid the possibility of failure of other machines connected to the pump. "Quick-dump" exhaust valve removes damp-cold exhaust gas through the main valve to reduce icing on the pump. ARO pneumatic diaphragm pump is one of the best quality pumps on the market.
