Kenrich Products

The Leader in Heavy Duty
Hand Grout Pumps since 1986!

Grout and Cement Types and 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 don't 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 grout pumps work with a wide range of cementitious grouts from all the leading manufacturers, including Five Star Grouts, Sika Grouts, and BASF Grouts.

Our heavy duty grout pumps are versatile enough to handle both standard pre-packaged mixed grouts and specialty grouts. 

Standard Grouts, Liquid and Flowable 

  • Cementitious grouts
  • Non-shrink grouts
  • Sand and unsanded based grouts
  • Metallic grouts
  • Grout bases and enhancers
  • Sludge
  • High temperature grouts
  • Cement Slurries
  • Tight clearance grouts

Below are a few of many types of grout that can be used in Kenrich Products heavy duty grout pumps:

Specialty Grouts and Unique Applications 

  • MasterEmaco S 440

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 for jagged edges, although some contractors have made it work.
