RMV25G30D-EZ | 2.5 GPM 3000 PSI EZ-Start Horizontal Pressure Pump

RMV25G30D-EZ Horizontal Axial Pump

The AR RMV25G30D-EZ is a horizontal axial cam pump engineered for pressure washer systems requiring strong
cleaning capability, compact mounting, and dependable long-term performance. Designed for 3,400 RPM gas
engines using a 3/4″ hollow shaft, this model delivers 2.5 GPM at 3,000 PSI—an output level well suited for
residential, commercial, and light contractor environments where higher pressure is needed to cut through
stubborn buildup. Its direct-drive configuration minimizes vibration and mechanical loss while supporting a
streamlined installation footprint for portable or fixed-frame cleaning units.

The pump integrates EZ Start technology, a complete unloader assembly with manual pressure adjustment, and a
downstream chemical injector to support detergent-assisted cleaning tasks. Built with ceramic plungers,
stainless-steel valves, and a maintenance-free crankcase, the RMV25G30D-EZ offers industrial-inspired
durability in a compact consumer/commercial package. It is engineered to provide consistent pressure,
simplified maintenance, and smooth operation for users who rely on predictable, high-performance output.

How the Pump Works

• Ceramic plungers pressurize water through stainless-steel valves for smooth, efficient discharge.
• Axial cam rotation drives all plungers uniformly, reducing vibration and energy loss.
• EZ Start relieves internal static pressure during ignition for easier cranking.
• Unloader diverts water to bypass when the spray trigger is released, preventing overpressure.
• Soap injector introduces detergents downstream for improved degreasing capability.
• Maintenance-free crankcase eliminates lubrication service requirements.

Operational Behavior

• Bypass cycles maintain system stability during intermittent trigger operation.
• Consistent flow supports a wide range of spray wands, turbo nozzles, and accessories.
• Low-vibration axial operation enhances operator comfort and engine longevity.
