High Pressure Air Driven Liquid Pumps
GZB Series

GZB Series Air Driven Liquified Gas Pumps:

The GZB series of liquefied gas pumps are unique; 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. GZB Series pumps are suitable for liquids, gases and vapors. Also capable of drawing a vacuum down to 11.25 psi(absolute) in 2-stage configuration.
