Buying Guide

Match voltage to your power source

Choose a 12V pump if you plan to run from a vehicle or auxiliary battery to avoid inverter losses and simplify wiring

Balance flow (gpm) and pressure (psi)

Higher gpm reduces refills for large jobs while 40–60 psi typically provides effective soft-wash coverage without surface damage

Prefer diaphragm pumps for chemical compatibility

Diaphragm designs resist corrosion from detergents and bleach better than many rotary impellers, increasing longevity in soft-wash use

Consider integrated pressure switches

Built-in pressure switches automate on/off cycling to maintain consistent application pressure and reduce battery draw

Check current draw and mounting needs

Verify amp draw (A) to size batteries or wiring correctly and confirm pump dimensions and fittings for secure mounting and hose compatibility
