GP-2 Grout Pump

Single diaphragm, large 4.6-gallon hopper, built to last.

Our most popular grout pump is the GP-2, a single diaphragm hand-operated model with the larger 4.6-gallon hopper. Capable of pumping up to six gallons per minute with a maximum output pressure of 15 psi. Weighing only 21 pounds, the GP-2 allows for great mobility. The supplied standard grout placement hose is 1 ½" ID by 5’ long clear vinyl tubing with a polished interior and a 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 503-281-6190.
