3500 PSI 5.6GPM 4.5 HP General Pressure Washer Pump Right Shaft 24 mm

Key Features

• The Industry Standard Frame: Widely recognized as the preferred triplex plunger pump frame in the commercial pressure cleaning industry, engineered for high-end reliability and extended operational lifespans.

• Nickel-Plated Forged Brass Manifold: Features an ultra-durable, corrosion-resistant nickel-plated forged brass manifold designed to handle intense fluid forces and heavy daily use.

• Premium Thermal & Load Management: Outfitted with an anodized die-cast aluminum oil-bath crankcase alongside heavy-duty tapered roller bearings and oversized connecting rods to minimize friction and maximize pump longevity.

• Solid Ceramic Plungers & Solid Seals: Engineered with robust solid ceramic plungers accompanied by continuously lubricated packings and unitized stainless steel inlet/discharge valves for consistent pressure delivery.

Important Buyer Notice: Accessory Packages

Please Read Before Purchasing: To accommodate manufacturing variations, this pump kit is shipped with one of two accessory combinations selected completely at random (as shown in the product media slider).

Both packages deliver high-grade operational components, but the specific layout of the unloader valves, thermal relief valves, fittings, or gauges will vary. Please review the item images closely prior to ordering.

Quick Installation Notes

• Check Crankcase Oil Level: Always verify the crankcase is filled to the center of the sight glass with proper non-detergent pump oil before starting the engine or motor. Running the pump dry will destroy the ceramic plungers.

• Verify Shaft Rotation Alignment: Ensure your power source (gas engine or electric motor) matches the right-hand drive configuration and keyway dimensions exactly before mounting.
