Buying Guide

Match flow (GPM) to nozzle and coverage

Higher GPM (e.g., 5.5 gpm) supports larger nozzles and faster coverage, while lower GPM suits targeted spot spraying

Choose appropriate pressure (PSI)

60 psi pumps are common for agricultural sprayers; ensure the pump's PSI aligns with the spray pattern and application rate you need

Pressure switch vs. manual control

Pumps with an integrated pressure switch automate on/off cycling and protect against overrun, improving convenience for larger jobs

Power and current draw

Confirm 12V compatibility and check amp draw (e.g., 8A) against your battery or power source to avoid power shortfalls

Durability and mounting fittings

Look for robust diaphragm construction and standard fittings (1/2 FNPT) for easier installation and longer service life
