How does this pump fit my existing pressure washer?

The VEVOR pump uses a standard SAE bolt pattern and a 3/4" horizontal drive shaft to match many common residential engines. It’s designed for rear outlet models that accept up to 3400 PSI and 2.5 GPM, so compatibility is broad across popular brands.

• Standard SAE bolt pattern for straightforward mounting
• 3/4" horizontal shaft and included shaft key for secure connection
• Compatible with many 196–230cc engines and rear outlet frames
• Fits brands such as RYOBI, Honda, Briggs & Stratton, Subaru, Simpson, and Craftsman

What performance should I expect during cleaning?

You’ll get a peak pressure rating up to 3400 PSI and a maximum flow of 2.5 gallons per minute, which is suitable for tough residential jobs while remaining fuel-efficient. This balance of pressure and flow removes dirt, mildew, and grime on common exterior surfaces without oversizing the power washer for homeowner use.

• Peak cleaning pressure up to 3400 PSI for stubborn stains
• 2.5 GPM flow rate for effective rinsing and detergent application
• Maintains steady pressure for consistent nozzle performance
• Good for sidewalks, fences, vehicles, and siding

How does the design help reliability and reduce leaks?

The pump features a one-piece head design and hardened plungers to improve sealing and wear resistance, reducing the chance of water or oil leakage. A metal shaft sleeve and reinforced seals help keep lubrication inside the crankcase and contaminants out, extending service life.

• One-piece pump head for improved sealing performance
• Hardened plunger surfaces minimize wear on seals
• Metal shaft sleeve prevents oil migration and shaft damage
• Sealed crankcase design reduces maintenance needs

What’s included and how easy is it to install?

The kit is supplied with common fasteners and accessories so you can replace the pump without specialty parts. It’s engineered for quick cold starts and does not require the user to relieve pressure before starting the engine, simplifying setup and first use.

• Detergent hose, 4 flat pads, 4 spring washers, and 4 bolts included
• UNF bolts (5/16-24 x 1) and 4.78 x 4.78 x 40 mm shaft key provided
• Maintenance-free crankcase design lowers user upkeep
• Quick-start design streamlines cold starts and initial operation

Who is this for: This VEVOR replacement pump is aimed at DIYers, homeowners, and small contractors who need a reliable, cost-effective replacement for a worn or leaking residential pressure-washer pump. It’s ideal if your machine uses a 3/4" horizontal shaft and supports up to 3400 PSI at 2.5 GPM, and you want an upgrade that reduces maintenance while restoring cleaning power.
