How the Pump Works

• Direct-drive axial cam mechanism efficiently converts engine rotation into
  high-pressure water flow, delivering steady output at 2.5 GPM and 2,800 PSI.
• The EZ Start system relieves static back pressure during startup,
  reducing pull-start effort and mechanical strain on both engine and pump.
• When the spray gun trigger is released, the integrated unloader
  diverts water into bypass, preventing over-pressurization of the system.
• During extended bypass operation, the TRV thermal relief valve
  opens to discharge overheated water and draw in cooler water, helping protect
  seals and internal components from heat damage.
• The VM manual control lets the operator fine-tune outlet
  pressure for different tasks, from delicate siding to stubborn concrete stains.
• The built-in chemical injector draws detergents into the low-pressure
  water stream for deeper cleaning results when needed.

Benefits

• Consistent cleaning power: 2.5 GPM at 2,800 PSI handles a wide
  range of residential and light commercial jobs.
• EZ Start convenience: Reduced startup resistance makes gas
  engines easier to pull-start and improves user comfort.
• Built-in protection: TRV prevents overheating during idle
  bypass operation to extend pump life.
• Precise control: VM manual control system lets users tailor
  pressure output to each surface and application.
• Durable internals: Ceramic plungers, stainless-steel valves,
  and heavy-duty seals are designed for long service life.
• Low maintenance: Factory-filled, sealed crankcase eliminates
  routine oil changes and reduces downtime.
• Ready to install: Ships pre-tested and filled so installers can
  mount, connect, and start cleaning quickly.

Typical Applications

• Driveways & Patios: Remove stains, dirt, and buildup from concrete and stone.
• Siding & Decks: Clean vinyl, brick, and wood surfaces without over-powering them.
• Vehicles & Small Fleets: Wash cars, light trucks, motorcycles, boats, and trailers.
• Outdoor Equipment: Rinse lawn mowers, garden tools, landscaping machines, and more.
• General Residential Cleaning: Ideal for whole-home exterior maintenance and seasonal cleanup.
