Heavy Duty Air Operated Grout Pumps: Kenrich GP-3A
The Kenrich model GP-3A grout pump is an air-operated single diaphragm grout pump. It is designed to pump most types of water based grouts. It is not suitable for use with chemical based epoxy grouts. This pump works for grouting hollow metal door frames in frames as well as placing grout anywhere that high pressure is not required.
A pneumatic cylinder is used to move the diaphragm up and down. When the cylinder retracts, the diaphragm draws the grout mixture through the open intake flapper valve into the pump. When the cylinder extends, the grout movement causes the intake flapper valve to close while opening to outlet flapper valve. This forces the grout mixture from the pump into the placement hose where it is directed to the work area.
