Our most popular pumps are single diaphragm hand-operated models. The GP-1 has a small 1.9-gallon hopper and can pump up to six gallons per minute with a maximum output pressure of 15 psi. Weighing only 19 pounds 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.

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.
