Category Manual & Transfer Pumps

Choose a water pump from required flow, total head, suction, water quality, pipe size, power, duty cycle, controls, and the maker's pump curve.

A transfer pump's distance depends on total head, flow, pipe diameter, friction, elevation, and its pump curve. Horizontal distance alone is not the limit.

Purge pump air by isolating power, filling or venting through the specified port, opening downstream air releases, and restarting according to the manual.

Prime a water pump by switching power off, filling the housing and suction line through its port, sealing it, opening valves, and checking for suction leaks.

One acre-foot equals about 325,851 U.S. gallons: one acre covered one foot deep. See the area-and-depth conversion and adjust the calculation for other flood depths.

A hand pump can operate while water supply, lubrication, seals, temperature, and user effort remain acceptable. Follow its duty and maintenance limits.

A pump may prime in seconds or minutes depending on suction lift, line volume, leaks, check valves, and design. Stop at the manual's dry-run limit.

Create a siphon by filling an airtight hose, keeping the source end submerged, and placing the outlet below source level. Prime safely and avoid contamination.

Choose a transfer pump by flow, total head, suction lift, water cleanliness, solids, hose size, power, duty cycle, and the manufacturer's pump curve.

A soaker hose has no fixed hourly output; length, pressure, design, elevation, and soil affect flow. Measure your setup with a meter or timed container test.
