Commercial Sink Pump System 1/2 HP

The Liberty 405 is a complete sink pump system built for commercial drainage applications. It uses a 1/2 hp motor rated at 115V AC and 7.3 A to move waste water through a 2 inch outlet. The package includes a polyolefin basin with a 5.5 gallon capacity and a vertical float switch for automatic operation.

Check voltage and basin space before ordering

Verify that a 115V AC circuit is available at the installation point and that the basin dimensions fit the planned location. The basin measures 13 3/4 inches in diameter and 14 1/8 inches in height with a 2 inch inlet. A piggyback plug on the switch requires a compatible receptacle for the float control to function correctly.

Upgrades from basic utility pumps

This system replaces standalone utility pumps that lack an integrated basin and automatic float control. The jump is worth it when a self-contained unit with 48.0 gpm flow at 5 feet of head simplifies installation and reduces the number of separate components needed for a commercial sink drain.

Questions about this item

Does the Liberty 405 system include everything needed for installation or are extra parts required?

The system includes the pump, a 5.5 gal polyolefin basin, vertical float switch with piggyback plug, 2 in inlet, 2 in outlet and 2 in vent connections. Piping, fittings and check valve are not included and must be purchased separately.

The Liberty 405 is listed as a single 1/2 HP model — are there different capacities or versions to choose from?

Only the 1/2 HP version with a 5.5 gal basin is offered under model 405. There are no alternate horsepower ratings or basin sizes for this specific model number.

What does the 48.0 gpm flow rate at 5 ft of head mean for actual drainage performance?

At a typical 5 ft discharge head the pump moves 48.0 gpm. Flow decreases to 44.0 gpm at 10 ft head and 39.0 gpm at 15 ft head, so pipe length and elevation will directly affect the drainage speed you see.
