Will this pump fit my pressure washer engine?

This pump is built for horizontal 3/4" shafts and commonly fits 160–230cc (5.5–8.0 HP) engines that use a standard SAE bolt pattern. It’s compatible with many popular brands when those mounting and shaft specifications match.

• Fits 3/4" horizontal shaft engines
• Recommended for 160–230cc, 5.5–8.0 HP engines
• Standard SAE bolt pattern for broad compatibility
• Often compatible with Simpson, Honda, Troy-Bilt, Generac, Delta models

How much cleaning power does the pump deliver and how should I use it?

The pump produces up to 3100 PSI and a maximum flow of 2.35 GPM, which is enough for heavy residential and many light commercial cleaning tasks. For longer life, operate around 2500 PSI rather than running it at peak pressure continuously.

• Maximum rating: 3100 PSI; typical recommended working pressure: ~2500 PSI
• Maximum flow: 2.35 GPM for effective rinsing and detergent use
• Suitable for driveways, siding, fences, vehicles, and equipment
• Avoid sustained operation at absolute maximum to extend lifespan

What’s included and how does the kit make installation easier?

The kit arrives with the pump and a set of installation and maintenance parts so you don’t need to source small components separately. Everything supplied is intended to simplify mounting, connection, and initial priming of the unit.

• One anodized replacement pump with maintenance-free crankcase
• Siphon tube with filter for drawing detergent or water supply
• Flat key, nozzle cleaning pin and hex bolts with spring washers
• All hardware required for secure attachment and basic servicing

How durable is the pump and does it need routine oiling?

The pump’s exterior is anodized to form a hard protective layer that resists rust and wear. It features a maintenance-free crankcase design, eliminating periodic oil changes required by some pump types — reducing upkeep while improving reliability in typical use.

• Anodized surface for improved corrosion resistance
• Maintenance-free crankcase removes the need for oil changes
• Use correct pressure and clean inlet filter to maximize life
• Periodic inspection of seals and fittings advised for long-term reliability
