Liberty Pumps HT450 1/2 HP Submersible Sump Pump

The Liberty Pumps HT450 is a 1/2 HP submersible sump pump designed for residential drainage. It operates on 115V AC single-phase power at 60 Hz drawing 7.3 amps. The unit features an aluminum body with an engineered polymer impeller and nitrile rubber shaft seal. No switch is included with this model.

Maximum Head 34 Feet Determines Installation

The pump delivers a maximum head of 34 feet which decides if it matches your discharge height requirement. Flow rates are 48.0 gpm at 5 feet of head, 44 gpm at 10 feet, 38.0 gpm at 15 feet and 32.0 gpm at 20 feet. A minimum sump pit diameter of 14 inches and minimum water depth of 14 inches are required for operation. Installations needing higher lift or smaller pits will not be served by this unit.

Oil-Filled Motor Runs Cool and Quiet Under Load

The oil-filled motor design dissipates heat efficiently during continuous pumping cycles. Submerged operation naturally suppresses mechanical noise in normal use. Power draw remains at the rated 7.3 amps on 115V supply when moving water within the published performance curve. The nitrile rubber shaft seal maintains integrity without external cooling requirements.

Questions about this item

What does the 48 gpm flow rate at 5 ft head mean for my basement?

At 5 ft of lift the pump moves 48 gallons per minute, so a typical 14 in pit can be cleared quickly during moderate inflow.

What does the 1-1/2 inch discharge and 115 V cord cap in practice?

The 1-1/2 in outlet fits standard PVC pipe and the 115 V plug draws 7.3 A on a regular household circuit.

What pit diameter and water depth does the HT450 need to fit and run?

It requires a minimum 14 in diameter pit and at least 14 in of water depth for proper submersion and cooling.
