Liberty PRG102A Grinder Pump 1 hp 230V AC

This Liberty grinder pump handles residential sewage with a 1 hp motor operating on 230V AC single-phase power. The CSCR motor drives a cast iron impeller and body for durability in demanding waste applications. A tether float switch with piggyback electrical connection provides automatic level control. It suits homeowners needing reliable solids-handling capability.

Upgrade from non-grinder effluent pumps

Replacing a standard effluent pump with this grinder model allows smaller discharge piping and handles tougher solids without clogging. The jump is worth it when the installation requires pumping sewage from a basement bathroom or where gravity sewer lines are unavailable. The 1 hp motor delivers the torque needed to macerate waste before discharge.

Practical limits of 230V single-phase grinder pumps

Maximum head reaches 50 ft with flow rates of 42 gpm at 10 ft, 39 gpm at 15 ft, 36 gpm at 20 ft and 15 gpm at 40 ft. The pump requires a minimum 24 in diameter sump pit for proper float operation. Switch actuation points are 13.7 in on and 6.7 in off, limiting use in shallow basins. California Proposition 65 warnings apply.

Questions about this item

What minimum sump pit diameter does the Liberty PRG102A require for mounting?

The pump needs a sump pit with a minimum diameter of 24 in to fit and operate correctly.

How is the pump installed and what step is often missed with the tether float switch?

Connect the piggyback plug to a 230V AC outlet, then plug the pump into the piggyback; the common mistake is not setting the tether length so the float travels freely between the 6.7 in off point and 13.7 in on point.

Which wear components will need replacement on this grinder pump over time?

The silicone carbide shaft seal and cast iron impeller are the primary wear items; inspect them when flow drops below the rated 42 gpm at 10 ft head or 36 gpm at 20 ft head.
