PEX Series Air Driven Liquefied Gas Pumps
The PEX series of liquefied gas 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.
Liquefied Gas Pump Applications
- Transfer, at pressure, of water, LPG, SF6, Freons and other refrigerant fluids.
- CO2 Fire Extinguisher filling.
- Hydro-static Pressure testing.
- Super critical extraction, including essential oils and caffeine.
- The transfer and/or extraction of LPG, LNG Freon and Refrigeration Fluids.
- Dust suppression.
- Used in R22, R134a, R470C, R410A, CO2, Propane, Butane, LPG and other liquefied gases.
- Recovery of residual fluid from large tanks.
