TOOLCY 1" Shaft Pressure Washer Pump 4400 PSI Triplex Ceramic Plungers with Adjustable Unloader, Brass Head

This high-performance replacement pump from TOOLCY is built to restore power to horizontal‑engine gas pressure washers that need higher cleaning pressure and durability. Designed with a fully anodized crankcase, brass pump head and a triplex ceramic plunger design, the unit delivers up to 4400 PSI and 4.2 GPM (recommended working pressure 3400 PSI at 3400 RPM) while fitting common engines such as Honda GX and various 9–15 HP models.

How does the TOOLCY pump improve cleaning performance?

The triplex configuration and brass pump head produce steadier flow and greater durability than single‑or double‑plunger pumps. That leads to stronger, more consistent spray patterns so you remove dirt faster across driveways, decks and vehicles without overworking the engine.

• Triplex ceramic plungers for smoother, high‑pressure output
• Brass pump head resists corrosion and extends service life
• Max 4400 PSI and 4.2 GPM capability for heavy cleaning tasks
• Recommended working pressure (3400 PSI @ 3400 RPM) for longevity

What makes installation and maintenance straightforward?

TOOLCY follows industry SAE flange dimensions and uses a 1" shaft opening to fit a wide range of engines, simplifying pump swaps. The pump arrives prefilled with oil and includes a sight glass so you can check levels quickly; regular oil changes every ~60 hours keep things running smoothly.

• Standard SAE mounting dimensions for easy replacement
• 1" shaft hole fits common engines (9–15 HP; 270–340 cc models)
• Prefilled oil and sight glass for quick maintenance checks
• Oil-change recommendation: approximately every 60 running hours

How does the adjustable unloader help during use?

The included adjustable unloader valve lets you tune pressure to match your engine and cleaning task, protecting the motor at idle and reducing noise when pressure release is needed. It improves cleaning efficiency by matching output to the nozzle and surface you’re working on.

• Adjust pressure to balance engine load and cleaning strength
• Reduce pressure for idle periods to lower noise and wear
• Optimizes pump performance for different spray tips and surfaces

What accessory features are included with the pump?

TOOLCY ships the pump with quick‑connect fittings and a set of nozzle tips to cover common spray angles, so you can tackle a range of cleaning jobs right away. The design also avoids a dipstick by using a sight glass, streamlining routine checks.

• 3/4" garden hose inlet and 3/8" quick‑connect outlet for fast hookups
• Complete five‑nozzle tip set for multiple spray patterns
• Sight glass replaces a dipstick for simpler oil inspection

Who is this for: The TOOLCY 1" Shaft Pressure Washer Pump suits homeowners, small contractors and light‑commercial operators who need a cost‑effective, durable pump replacement for horizontal‑shaft gas engines (common in Honda GX series, Briggs & Stratton and similar 9–15 HP units). It’s ideal if you want improved pressure and flow for heavy‑duty cleaning tasks while keeping installation and maintenance straightforward.
