Simplex sewage ejector system

This Liberty P382LE51 system handles residential or light-commercial sewage ejection with a single 1/2 HP pump rated for 115 V, 60 Hz operation. The polyethylene basin holds 41.0 gallons and the tether-float switch is integrally wired for automatic cycling. Maximum head reaches 24 ft and the pump passes solids up to 2 in diameter.

Installers needing a compact, single-pump package

The 24 in by 24 in footprint suits tight basement or crawl-space locations where a simplex arrangement is specified. Sites requiring duplex redundancy, higher head pressure, or three-phase power will need a different configuration. Buyers who want more storage capacity or a larger solids passage should look at other models.

41.0-gallon polyethylene basin capacity

Basin volume determines how often the pump cycles and whether the system can absorb surges from laundry, bathrooms, or kitchen fixtures. The 10 ft power cord and 140°F maximum liquid temperature are fixed by the design. Verify that the 24 ft shut-off head matches the discharge elevation before purchase.

Questions about this item

Should I pick the 41.0 gallon basin or a smaller size for my septic setup?

This system comes as a single 41.0 gallon polyethylene basin with a 1/2 HP pump rated for 2 inch solids, so the capacity is fixed for this model.

What does the 140.0 gpm flow rate at 5 ft head mean when the pump is installed?

At 5 feet of discharge head the pump moves 140.0 gallons per minute; at 10 ft it drops to 118.0 gpm, at 15 ft to 92.0 gpm, and at 20 ft to 55.0 gpm, with a maximum shut-off head of 24 ft.

How does the 115V 60 Hz tether-float switch limit the installation?

The integral tether float runs on 115V AC single-phase power with a 10 ft cord, so the basin must be placed within reach of a standard household outlet and the float needs clearance to swing freely.
