Why customers choose Cera Garden

Refresh your AR42940 compatible pressure washer with AUTOBABA's Pump Head Assembly. Designed for AR-series RMW and SRMW axial cam pumps, this kit combines precision engineering with durable materials to support reliable operation under typical cleaning tasks. Rather than a simple replacement, it offers a thoughtfully engineered upgrade that emphasizes sealing integrity and smooth performance.

Fitment and what's inside

Compatibility notes and included components help you plan a straightforward installation. The kit is intended for 2.2 GPM pumps in the RMW/SRMW family.

  • FITMENT: Works with selected RMW/SRMW axial cam pumps such as RMW2G20, RMW2.2G24, SRMW2.2G26; not suitable for 2.4 GPM SRMW models or 2.5G series.
  • COMPONENTS: Pump head, water seals, check valves, unloader valve, chemical injector, EZ start valve, thermal relief valve, and inlet/outlet tube are included.
  • DESIGN: Advanced welding enhances sealing performance and helps reduce leakage and low water level issues during high-pressure use.
  • HIGH QUALITY: Aluminum construction delivers hardness, light weight, heat resistance, and corrosion protection for longer service life.

Practical benefits you may notice

  • Potential for more consistent seal performance and fewer leaks on compatible AR pumps.
  • Durable aluminum head that stands up to heat and outdoor conditions.
  • All-in-one kit that covers essential valves and fittings for quick maintenance.
  • Ready-to-install components designed for straightforward mounting on RMW/SRMW systems.

Designed with real-world use in mind, this pump head assembly aims to help you revitalise an aging pump or upgrade an older AR42940-equipped machine. The combination of robust materials, precise fit, and included accessories offers a practical path to restoring performance without replacing an entire system.
