Grout and Cement Types & Flow

Kenrich heavy duty grout pumps will pump most of your prepackaged general purpose non shrink cementitious grouts, including sand based grouts and cement mixes. We do not recommend the use of epoxy or hybrid grouts in our pumps, however under certain conditions, some will work. Contact our Kenrich sales office for more information.

 Kenrich pumps work with a wide range of cementitious grouts from all the leading manufacturers, including Five Star Grouts, Sika Grouts and BASF Grouts. We can pump both your standard pre-packaged mixed grouts, as well as your specialty grouts.

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 factory 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.
