SRMW22G28-EZ 2.2 GPM 2800 PSI | EZ-start vertical pump

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.

Benefits of the SRMW22G28-EZ

• Higher Pressure Output: 2800 PSI for tougher residential and light commercial cleaning tasks.
• Extended Durability: Reinforced components withstand heavier and more frequent use.
• Engine-Friendly Design: EZ Start system reduces pull-start resistance and startup load.
• Built-In Safety: Factory-installed TRV protects the pump from overheating in bypass.
• Versatile Performance: Adjustable pressure and soap injection for a wide range of surfaces.
