A unique valveless mechanism (internationally patented) helps retain water inside the pump even without a check valve when the pump is turned off. This prevents the pump from running dry and is another feature of our advanced valveless technology.
When most pumps run dry, the friction from the contact points will cause parts, such as the shaft and the bushing, to break down from excess heat. The original anit-heat construction of GS/GSF prevents the pump from a heat deformation because the materials used for the contact point works in lowering the temperature by radiating and insulating heat.

Ultra Pure Pneumatic Diaphragm Pumps
The original air-releasing construction of the rear casing is useful for the prevention of the "air lock" problem.
Internationally patented PPS bushing construction
Carbon fiber, adopted for the reinforcement of the rear casing, makes the pump strong against burst pressure.
A selection of the bushings available for the different types of chemicals and the presence of slurry. (Common parts used to minimize stock requirements)
Available bushing materials are: carbon, ceramic, PTFE and SiC.
