PEX Series Air Driven Liquid Pump
The PEX series of liquid pumps are unique in the ProTech range as they use pistons rather than plungers in the liquid ends. This enables them to achieve high pressure fluid outlet flows in both directions of the reciprocating pump action, making them double acting and very efficient. All PEX Series pumps are suitable for liquids, gases and vapours. They are also capable of drawing a vacuum down to 11.25 psi(absolute) in the 2-stage configuration.
