An Air operated liquid pump for pressure testing, chemical injection and hydraulic power. The Haskel AW-150 Air Driven Liquid Pump is a reciprocating, positive displacement pump with a directly coupled, integral linear reciprocating air motor, designed to generate High Pressure Liquid flow. The pressure increase is made possible by means of the area ratio between the larger diameter air drive piston directly connected to a smaller diameter liquid plunger/piston. Using our various material and seal options they are suitable for pumping a wide range of liquids including water, oil, water/glycol and many other chemical fluids.
Features:
Safe pneumatic operation – no heat, flame or spark risk
