Kenrich Products

The Leader in Heavy Duty
Hand Grout Pumps since 1986!

GP-6 / Kenrich’s Largest Heavy Duty Grout Pump

Hand Operated, Twin Diaphragm, 4.6 Gal. Hopper

Our model GP-6 is a twin diaphragm hand-operated grout pump. This pump features two separate diaphragms mounted side-by-side and are connected together by common inlet and outlet cast aluminum manifolds. A single pump handle operates both pumps. The advantage of two diaphragms is a much smoother output flow as well as effectively doubling the output volume. Output capacity is up to twelve gallons per minute and is a popular choice for filling hollow concrete block.

The supplied standard grout placement hose is 1 ½" ID by 5’ long clear vinyl tubing with a polished interior and rigid straight steel tube in the end. Optional 1 ½" hoses available in 10’, 15’ and 20’ lengths. Popular options include our ¾" and 1" hose reducer kits which attach directly to the outlet of the pump and are used in place of the standard 1 ½" hose.

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 1-503-281-6190.
