SRMW22G28-EZ Annovi Reverberi Vertical Pressure Washer Pump – 2.2 GPM, 2800 PSI
- The SRMW22G28-EZ is a reinforced axial cam, vertical-drive pressure washer pump
designed for residential, light commercial, and small industrial applications. - Delivers 2.2 GPM at 2800 PSI while running at 3400 RPM, providing higher pressure
output and smooth operation in a compact package. - Mounts directly to gas engines with a 7/8″ vertical shaft, making it an ideal replacement and
upgrade for standard vertical OEM pumps. - Includes EZ Start technology, a factory-installed thermal relief valve, integrated unloader, and a
maintenance-free synthetic oil crankcase for long service life with minimal upkeep.

How the SRMW22G28-EZ Works
- A reinforced axial cam plunger system generates steady flow and pressure while minimizing wear on
seals and bearings. - EZ Start technology eliminates static back pressure at startup, making pull-starts easier and
reducing engine load and component stress. - The integrated unloader automatically diverts flow to bypass when the spray gun trigger is
released, preventing over-pressurization. - The thermal relief valve (TRV) opens automatically to release overheated water when the pump is
left in bypass, protecting seals and internal components. - A built-in soap injector allows detergents and cleaning agents to be drawn into the water stream
for deeper cleaning. - The maintenance-free crankcase comes factory-filled with premium synthetic oil, eliminating the
need for lubrication service under normal use.
Premium Features
- Heavy-Duty SRMW Build: Reinforced internals for longer service life than standard vertical pumps.
- EZ Start Technology: Smoother, easier startups with less engine strain.
- Thermal Relief Protection: TRV helps prevent heat damage during extended bypass periods.
- Integrated Pressure Control: Manual unloader adjustment for dialing in the right PSI.
- Detergent Injection: Built-in soap injector for grease, oil, and heavy soil removal.
- Synthetic Oil Fill: Lifetime lubrication in a sealed, maintenance-free crankcase.
