Buying Guide

Match pump type to application

Choose diaphragm pumps for pressure delivery and on-demand use, transfer pumps for bulk liquid movement, and bottled-dispense units for countertop or office water

Check flow rate (GPM)

Select higher GPM for fast transfer or continuous flow; 3–7 GPM suits garden, RV, and general household needs, while lower GPM fits bottled dispensing

Confirm pressure (PSI)

Pressure rating (45–70 PSI common here) affects tap feel and system compatibility; higher PSI helps with long runs and appliance feed

Match voltage and power

Verify 110–115V AC models for mains use and 12V DC for portable/vehicle power to ensure electrical compatibility

Look for self-priming and dry-run protection

Self-priming pumps and built-in protection prevent damage during intermittent use and simplify installation and maintenance
