Product identity

The Liberty Pumps LSG203M is a 2 hp grinder pump designed for residential or light commercial sewage handling. It operates on 208/230 V three-phase power at 60 Hz and draws 10.6 A. The unit has a cast iron body, stainless steel impeller and silicon carbide Viton shaft seal. No switch is included.

Deciding specification

The pump delivers 50.0 gpm at 10, 15 and 20 ft of head, 48.0 gpm at 40 ft and 42.0 gpm at 60 ft. This flow-versus-head profile is the single figure that determines whether the pump matches the system curve. Buyers must compare these points to their required discharge pressure and volume.

Suitability

This model suits installations that can supply three-phase 208/230 V power and need a grinder pump without a built-in float switch. It is not for sites limited to single-phase supply, for applications requiring an integrated tether float, or for systems demanding higher flow at heads beyond 60 ft.

Questions about this item

What does 50.0 gpm at 10 ft of head mean for real-world drainage?

The pump moves 50.0 gallons per minute against a 10 ft lift, so it clears basins quickly in typical residential lift-station installs.

How does the 208/230 V 3-phase supply limit motor performance?

The 3-phase, 60 Hz, 10.6 A feed lets the 2 hp motor develop full torque without single-phase starting components.

What discharge size and mounting style does the cast-iron body need?

The unit uses a tether-float design with a vertical discharge flange that bolts to standard guide-rail or stationary bases.
