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.
- Designed for horizontal shaft gas engines.

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.
