Pumps for mix head hydraulic systems

Don't get stuck constantly replacing aluminum-body hydraulic pumps that fail under the demands of polyurethane foam manufacturing. Our pumps feature cast iron bodies designed specifically for the dirt and pressure spikes typically found in mixhead hydraulic systems.

We offer a wide range of hydraulic pumps from Rexroth and other manufacturers, including:

  • Internal gear pumps
  • External gear pumps
  • Radial piston pumps
  • Axial piston pumps

We supply only hydraulic pumps that represent the best in quality, performance and value for the production of urethane foam. Our process experts can help you select the correct pump for your system and application.
