Which machines will this pump fit?

How durable is the TOOLCY replacement pump?

The pump uses a high-performance double-seal arrangement and upgraded piston and bearing surfaces to reduce leakage and wear. TOOLCY specifies an expected running time significantly longer than many OEM pumps when installed and used correctly.

• Double-seal system to prevent oil and water intrusion
• Improved piston and bearing surfacing for extended service life (approx. 150 hours stated)
• Thermal relief valve (TRV) to protect during bypass and reduce overheating risk

Is installation and maintenance difficult?

Installation is designed to be straightforward: the pump ships pre-filled with oil and uses a keyed 7/8" shaft for quick alignment. TOOLCY includes three matched nozzles (0°, 25°, soap) so you can start cleaning immediately and expect minimal initial setup time.

• Pre-filled crankcase — no pre-filling or oil changes required out of the box
• Quick 5–10 minute fit using the shaft key and rear inlet alignment
• Includes 0°, 25°, and soap nozzles for immediate use

What performance can I expect for cleaning jobs?

With a maximum of 3100 PSI and a 2.5 GPM flow rate at roughly 3400 RPM, this pump suits medium-duty cleaning tasks such as driveways, decks, vehicles, patios, and light roof work. It delivers a balance of pressure and flow to cover multiple outdoor cleaning needs without overtaxing compatible small engines.

• 3100 PSI max for effective dirt and grime removal
• 2.5 GPM for steady water flow and coverage
• Operates around 3400 RPM on recommended engines
