This YAMATIC vertical pressure washer pump replaces worn-out units in Honda GCV190, Ryobi, Simpson, and other brands with 7/8" shafts, delivering 3000 PSI at 2.5 GPM for powerful cleaning. Its durable seals, adjustable unloader, and 5-10 minute installation make it perfect for DIYers reviving 180-196cc power washers.

  • Revive your power washer affordably by replacing just the pump instead of the entire unit
  • Delivers max 3000 PSI at 2.5 GPM for tough cleaning of walls, vehicles, and driveways
  • Extended 150-hour runtime with double seals and upgraded pistons for lasting performance
  • Adjustable unloader and thermal relief valve optimize pressure and prevent overheating

Easy bolt-on installation in minutes without special tools. High compatibility across major brands like Honda GCV190 and Ryobi RY802700A. Durable construction with leak-proof seals for reliable long-term use.

Not compatible with pressure washers featuring idle-down functionality. Requires specific 180-196cc engines at 3400 RPM for optimal performance. Lacks pre-filled oil, so initial filling is needed before first use.

Welcome to the premier destination for YAMATIC washer pumps, your go-to source for high-performance replacement parts in the Windshield Wipers & Parts category.

Why Choose YAMATIC Washer Pumps?

YAMATIC has built a solid reputation for delivering durable, high-quality replacement pumps that outperform standard options in pressure and longevity. What sets YAMATIC apart is their focus on precision engineering, using corrosion-resistant materials and optimized designs for seamless integration into existing systems. Whether you're a DIY mechanic fixing a faulty windshield washer or a professional servicing power washers, these pumps provide consistent flow rates and high PSI ratings to handle demanding conditions. As part of our expansive Replacement Parts lineup, YAMATIC products emphasize reliability without compromising on affordability.

Key Features to Consider When Shopping YAMATIC Washer Pumps

When selecting a YAMATIC washer pump, prioritize factors like shaft size, mounting orientation, pressure output, flow rate, and compatibility. Shaft diameter ensures a perfect fit—3/4-inch for many standard setups, while 7/8-inch suits larger applications. Horizontal or vertical mounting accommodates various engine configurations, and PSI/GPM ratings determine cleaning power: higher PSI for stubborn grime, steady GPM for efficient coverage.

  • Pressure and Flow: Models range from 3000-3400 PSI at 2.5 GPM, ideal for automotive washers and pressure systems.
  • Compatibility: Direct replacements for Homelite, Troybilt, Simpson, Karcher, Honda GC160/GC190, and OEM numbers like 308653045.
  • Build Quality: Aluminum heads, brass fittings, and sealed bearings resist wear from water and debris.
  • Inlet/Outlet Design: Rear inlet/outlet options simplify installations in tight spaces.

Comparing YAMATIC Models: Horizontal vs. Vertical Pumps

YAMATIC offers two standout models in this category, each tailored to specific needs. The 3/4-inch shaft horizontal pump delivers 3400 PSI at 2.5 GPM, making it perfect for power washers compatible with Homelite, Troybilt, Simpson, Karcher, and Honda GC-series engines. Its horizontal design excels in space-constrained engine bays, providing maximum pressure for heavy-duty cleaning.

In contrast, the 7/8-inch shaft vertical pump operates at 3000 PSI and 2.5 GPM with rear inlet/outlet, ideal for upright mounting in models like those with part numbers 308653045, 308653052, 308653078, and GCV190 engines. Choose the horizontal for broader compatibility and higher PSI if your setup demands intense pressure; opt for the vertical for stable vertical installations and easy plumbing. Both outperform generics, but matching shaft size and orientation to your equipment prevents leaks and ensures longevity.

Common Use Cases for YAMATIC Washer Pumps

These pumps shine in automotive maintenance and power washing scenarios:

  • Replacing weak windshield washer pumps on trucks and SUVs for better spray reach.
  • Upgrading pressure washers for home or commercial use, restoring full PSI after wear.
  • Custom builds or repairs on equipment from brands like Honda, where OEM replacements are scarce.
  • Preventive maintenance in fleets to avoid downtime from fluid delivery failures.

If YAMATIC doesn't match your specs, explore alternatives like A-Premium Washer Pumps or Trico Washer Pumps for similar high-performance options.
