RMV25G30D-EZ3/8 | 2.5 GPM 3000 PSI EZ-Start Pressure Pump 3/8 Outlet

RMV25G30D-EZ3/8 Horizontal Axial Pump

The AR RMV25G30D-EZ3/8 is a horizontal axial cam pump engineered for residential, commercial, and light-duty
contractor applications requiring a compact direct-drive solution with dependable operating performance.
Delivering 2.5 GPM at 3,000 PSI and designed for 3,400 RPM gas-engine platforms, this model provides strong,
consistent cleaning power while maintaining a streamlined footprint suited for portable frames and small
equipment bays. With a 3/4″ hollow shaft for direct engine mounting and a 3/8″ NPT threaded outlet for
simplified hose connection, the pump offers installation efficiency and long-term reliability for operators
who need durable performance with minimal maintenance requirements.

The RMV25G30D-EZ3/8 integrates several operational enhancements including EZ Start technology, an internal
unloader with manual pressure adjustment, and a built-in downstream soap injector. These features reduce
engine strain during ignition, support steady operating pressure, and improve cleaning capability when
detergents are required. Engineered within AR’s RMV platform, the pump is constructed with ceramic plungers,
stainless valves, and a maintenance-free crankcase, ensuring stable hydraulic output and dependable service
life for homeowners, small shops, and mobile service operators.
