Metal vs. Heavy Duty Plastic Grout Pump Bodies

All of Kenrich's grout pumps are available with metal or heavy duty plastic bodies.

Differences Between Metal and Heavy Duty Plastic Grout Pumps

  • Metal Grout Pumps

    All models of Kenrich Grout Pumps can also be ordered with a metal pump body assembly. These metal components are even more durable and resistant to abuse than our standard plastic bodies.
  • Heavy Duty Plastic Grout Pumps 

    The most popular and best-selling grout pump that Kenrich Products manufacturers, is the plastic grout pump. After 30 years, many of our original GP-1 plastic grout pumps are still in use, withstanding the test of time.
