Pressure Washer Pumps

Match the pump's pressure (PSI) and flow (GPM) to the tasks you plan—higher PSI for hard surfaces and higher GPM for faster rinsing; ensure compatibility with your pressure washer's motor/engine and connector types

Common types are axial cam (lighter, quieter, lower cost) and triplex plunger (more durable, higher pressure and flow); axial cam suits light-to-moderate home use, while triplex is better for frequent heavy-duty cleaning

Replacement and standalone pumps in the garden and patio category typically range from budget options under $50 to professional-style units several hundred dollars, with average prices around $80–$100 for mid-range models

Look for corrosion-resistant materials (ceramic pistons, brass fittings), sealed bearings, thermal relief valves, and easy-to-service seals and valves to extend life and simplify repairs

Use clean, filtered water, run pump on low pressure briefly before storage, change pump oil per manufacturer intervals (if applicable), winterize with antifreeze or pump saver in freezing conditions, and replace worn seals promptly

Pumps are not fully universal; you should match mounting bolt pattern, shaft size, drive type, inlet/outlet fittings, and performance specs to your unit or choose a compatible adapter kit

Simple tasks like replacing seals, O-rings, or unblocking inlet screens can be DIY with basic tools and a service kit, but internal failures (worn pistons, cracked housings) often require professional repair or pump replacement
