Buying Guide

Match pump type to your task

Choose diaphragm pumps for pressurized delivery and self-priming transfer pumps for moving bulk water or portable use

Confirm flow rate and pressure

Select pumps with GPM and PSI ratings that meet your needs—higher GPM for fill/transfer, higher PSI for pressurized dispensing

Check power compatibility

Pick 110–115VAC models for household and RV shore power or 12V DC units for battery-powered portable use

Look for self-priming and on-demand features

Self-priming and on-demand switches simplify installation and prevent dry-run damage in intermittent-use systems

Consider build and installation needs

Evaluate mounting orientation, inlet/outlet sizes, included hose kits, and corrosion-resistant materials for longevity
