Description

FEATURES

The Liberty LE74M2-2 Pump is a 3-phase manual submersible sewage pump with a 3/4 HP, 440-480v motor and a 25' quick-disconnect power cord. A separate approved pump control device or panel is required for automatic operation. Featuring rugged 2-vane, semi-open impellers, this allows for handling of 2" solids.

The heavy-duty built Liberty Pumps LE74M2-2 sewage pumps are ideal for residential and light commercial sewage applications. 3-Phase Liberty Pumps require panel for automatic operation. Check three phase pumps for proper rotation prior to installing pumps in the basin. To change rotation, reverse any two of the three power leads to the pump.

Features:

Rugged 2 vane, semi-open cast iron impellers
Cast iron housings and volute with all stainless and brass fasteners
416 stainless steel rotor shaft
Oil-filled, hermetically sealed motors
Built-in thermal protection on single phase models
Permanently lubricated upper and lower ball bearings
Unitized shaft seals
Single float mechanical level control with series plug for manual bypass operation-standard on single-phase automatic models

Buyers Guides

Liberty's LE family of pumps are submersible sewage pumps designed for home or residential applications. All LE pumps handle waste solids up to 2" in diameter. The family includes four series: the LE40, LE50, LE70 and LE100. The number designations are meant to denote the horsepower difference between each series - so the LE50 will operate at 1/2 HP, the LE70 will operate at 3/4 HP and so on. Each pump in the four series is close coupled, built with a corrosion resistant, cast iron body that houses an oil-filled, hermetically sealed motor. The voltage ranges and phases of power will vary by series and model.
