The 530008 triplex plunger pump is an OEM AAA replacement pump designed for high-pressure cleaning applications.

It delivers up to 3700 PSI at 2.5 GPM and is engineered to reduce engine load while maintaining consistent output performance.

This 530008 pump features a horizontal shaft configuration with a 3/4-inch shaft diameter and a SAE J-609A flange pattern, making it compatible with a wide range of gas engines.

It includes an adjustable unloader system, integrated thermal relief protection, and a sight glass oil system for monitoring lubrication without a dipstick.

530008 AAA Pump Features

  • Triplex plunger pump for pressure washer systems.
  • PowerBoost technology for increased pressure at the nozzle.
  • Fully adjustable unloader system with ergonomic control.
  • Integrated sight glass for oil level monitoring.
  • Thermal relief protection to prevent overheating.
  • Dual oversized radial ball bearings for reduced friction.
  • Ceramic-coated pistons for extended seal life.
  • Anodized aluminum crankcase for corrosion resistance.
  • Sealed crankcase design to prevent contamination.

Service Note

The "Burst Pressure" of a pressure washer pump is the highest pressure the pump produces when in a static position and when the trigger is first squeezed. This represents the initial surge of pressure and does not reflect the actual operating pressure.

The actual operating PSI of a pump is determined by factors such as the engine horsepower and the nozzle size being used, which restricts water flow and creates back pressure within the system.

A single pump may be rated at different GPM and maximum PSI levels depending on variables such as engine RPM, nozzle size, and engine horsepower.
