GP-7 Grout Pump

Dual 1” vinyl hoses, ideal for filling both sides of a door frame simultaneously.

The GP-7 is a twin diaphragm hand-operated grout pump that is used specifically for grouting metal door frames. Having two 1" output hoses allows the contractor to fill both sides simultaneously. Requires two 1" minimum diameter holes be drilled in each side of the door frame and using the supplied hose support assembly holds the two hoses in place. Net weight is only 35 pounds.

The GP-7 is a twin diaphragm hand-operated grout pump. This pump features two separate pumps mounted side-by-side, each with their own inlet and outlet cast aluminum manifolds. A single pump handle operates both pumps. The advantage of two diaphragms is a much smoother output flow.

The standard boom assembly is adjustable to fit a 34" to 48" wide door frames. Optional hose support extended assemblies are also available to fit wider doorways, including 48” to 60” and 60” to 72”. The supplied standard grout placement hose is 1" ID by 6’ long clear vinyl tubing with a polished interior.

Pumping Aggregate Materials Through Your Kenrich Grout Pump.

The Kenrich line of heavy-duty grout pumps are designed to pump non-shrink sand based cementitious grouts. However if you need to pump Grout with AGGREGATE, we recommend a factor premix Grout in the bags with no bigger than 3/8” pea gravel. Crushed rock/stone 3/8" in size and larger, not recommended do to jagged edges, even though some contractors make it work. Call the office for more info at 503-281-6190.
