Refresh your pressure washer with the YAMATIC horizontal pump

Revitalize an aging pressure washer by swapping in the YAMATIC 3-4 shaft horizontal pump. Capable of delivering up to 3200 PSI and 2.5 GPM, this replacement unit helps you restore strong cleaning power without buying a whole new machine. Designed to fit a wide range of engines and popular brands, it supports tasks from stubborn stains on driveways to routine vehicle washing, all with a focus on dependable performance.

Why consider a pump replacement

Replacing the pump can extend the life of your existing system and reduce downtime. If seals are leaking or pressure is uneven, a fresh pump can restore consistent spray while keeping your current engine and frame in use. This model is suited for engines in the 208-220cc range (roughly 6.5-7.0 HP) and is compatible with several well-known brands, offering a practical upgrade path rather than a full buy-and-replace cycle.

• Powerful performance: up to 3200 PSI and 2.5 GPM for versatile outdoor cleaning.
• Durable build and improved components: double seal system and upgraded piston for longer life.
• Safety and control: adjustable unloader and thermal relief valve help manage heat and pressure during use.

Key durability and control features

• Double seal system reduces leaks and extends service life under heavy use.
• Adjustable unloader lets you tailor pressure to match your engine and job needs.
• Thermal relief valve protects the pump when bypassing, helping prevent overheating.

• Included components: siphon tube with filter, mounting bolts, shaft key, and an instruction booklet.
