Himore pressure washer pump compatible with Honda Excell XR2500/XR2600 — horizontal mount, 2600 PSI 2.4 GPM

The Himore horizontal pressure-washer pump replaces worn OEM units compatible with Honda Excell XR2500, XR2600, XC2600, EXHA2425 and XR2625 models, delivering up to 2600 PSI at 2.4 GPM with an integrated chemical injector and thermal relief.

This replacement pump is built to fit horizontal-mount gas pressure-washer frames and gives you the hardware and service points needed for reliable cleaning performance. Read all fitment details carefully — shaft size, bolt pattern, and mounting orientation matter for a correct swap. If you're unsure which pump your machine requires, gather your model, code/serial numbers, and engine horsepower before contacting us or making a purchase.

Will this pump fit my Honda Excell model?

Compatibility depends on several measurable features rather than model names alone. Confirm the pump’s 7/8" hollow short shaft, bolt hole pattern, and horizontal mounting orientation match your unit. The listing includes bolt-center measurements and shaft/key dimensions to help verify fit.

• Shaft diameter: 7/8" hollow short shaft
• Bolt pattern: 2 5/8" center-to-center and 1 7/8" to each outer hole
• Keyway: 3/16" width × 1 1/8" length

What performance and operating limits should I expect?

The pump is rated for a maximum pressure of 2600 PSI and a flow of 2.4 GPM, with a top pump speed of 3400 RPM. It’s intended for systems driven by engines up to about 6.5 GHP and handles water temperatures up to 140°F. These specs help match the pump to the engine and cleaning tasks.

• Maximum pressure: 2600 PSI; maximum flow: 2.4 GPM
• Max pump speed: 3400 RPM; max horsepower: 6.5 GHP
• Max water temperature: 140°F

What components and maintenance features are included?

This unit ships as a ready-to-install horizontal pump with common service items already in place: chemical injector, unloader valve, thermal relief valve, outlet tube, oil cap, hose, and keyway. It also offers a sight glass and drain plug for quick oil checks and changes. Note: 85W-90 gear oil (75 mL) is required but not included.

• Supplied: chemical injector, unloader, thermal relief, outlet tube, oil cap, hose, and key
• Oil capacity: 75 mL (2.5 oz) of 85W-90 gear oil (not included)
• Sight glass and drain plug for simplified maintenance

Are there installation cautions or special instructions?

Install the pump in a horizontal orientation — the oil cap must point upward — because the pump head cannot be flipped. Ensure your engine provides at least 5 HP to reach rated PSI. If you plan to use a quick-connect outlet, remove the preinstalled brass outlet tube first.

• Mount horizontal only; oil cap faces up
• Requires minimum ~5 HP to reach specified PSI
• Remove brass outlet tube for quick-connect fittings
