Designed for real-world use, this head offers a precise fit and a straightforward replacement experience. It supports a range of compatible pumps, including SRMW2.2G26, SRMW22G26, SRMW22G26-EZ, SRMW22G26-EZ-SX, RMW2.2G24, and RMW2.2G20D, enabling smooth operation with minimal fuss.

Key compatibility

  • RMW2.2G24 and RMW2.2G20D

What to expect during use

The head is designed for easy transfer of the existing oil unloader and valve seat to the new unit, followed by adjusting the oil unloader valve tightness. This simple swap can save time and reduce downtime when servicing multiple machines.

How to install (simple steps)

  • Remove the oil unloader and valve seat from the old head
  • Place them onto the new pump head
  • Adjust the tightness of the oil unloader valve to suit your system
  • Connect to a compatible SRMW or RMW pump and test operation

Notes: To remove the seat, you’ll need an M6-1.0 bolt about 2 inches long. Screw it into the seat and gently pull to lift it free. This product is designed for SRMW 2.2 GPM pumps and is not available for SRMW 2.4 GPM, RMW2.5G28, or SRMW2.4G28 models.
