Our Short and Long Term Experiences Installing and Using the Liberty Pumps P372LE51 Sewage Package

You’ll also benefit from a much stronger motor at 1 hp in the PRG101A as well as more than twice the maximum pumping height at 50 feet vs 24 feet. If that’s what you need, you don’t want to try to save money with the P372LE51A. As a grinder, it can handle things that shouldn’t be flushed down toilets but are flushed anyway. It’s not going to get clogged with feminine hygiene products, wipes, napkins, towels, or similar difficult solids. The PRG101A is a superior sewage pump due to its being a grinder pump instead of an ejector pump. Pumping speeds are slower in the P372LE51 than in the LE51A due to its configuration within the basin, although max head remains the same.Ĭompared to the PRG101A, the P372LE51A is a faster pump (8,400 GPH vs 2,760 GPH) but its speed, its price, and its integration within the basin are its only advantages. Installation is simpler due to the integrated pump, discharge, and float switch components. The basin is also larger than the typical 18 inch x 30 inch basin, resulting in an up to 40% reduction in both pump and switch cycles and greater life in both components.

The biggest difference between the P372LE51 and the LE51A and M267 is that the P372LE51 is a pre-assembled sewage ejector package instead of just the pump (i.e., the LE51A), the sewage basin is included as well as the QuickTree system to allow removal and replacement of float switches without affecting either the pump or plumbing. How Does the Liberty Pumps P372LE51 Compare to the Liberty Pumps LE51A, Zoeller M267, and Liberty Pumps PRG101A? The system arrives completely assembled and includes a clear plastic overhead cover to protect the system during rough-in and masonry work. The pump itself is secured within the 41-gallon basin, which itself is constructed of polyethylene and is 40% larger than standard 18 inch x 30 inch basins in order to improve both pump and switch life by reducing on/off cycles. This is done through a top inspection cover fitted with integrated rubber seals. The primary features of the system include the QuickTree system, through which the float switch can easily be accessed, pulled, and replaced through the top of the basin without affecting the functionality or connections to the pump or plumbing. The maximum pumping speed of the P372LE51 lower than that of the LE51A by itself it peaks at 8,400 GPH at zero feet, which scales down to 6,480 GPH at 10 feet, 2,640 GPH at 20 feet, and shuts off at 24 feet at max head. The pump includes a 2 inch FNPT discharge.

It can handle liquids up to 140F and an automatic mechanical wide angle float switch is packaged with the pump. The motor draws 115 volts single phase AC via 12 amps at maximum load locked rotor amps is reached at 22.5 amps while thermal overload protection kicks in at 221F. The P372LE51 can pass 2 inch spherical solids and includes thermal protection in the motor. It is 30 inches tall, 20-1/4 inches wide at the base, and 24-1/2 inches across at its widest point. The package is backed by Liberty Pump’s 3 year warranty. It includes the LE51A sewage ejector pump, which includes a 1/2 horsepower electric motor throttled down to a 8,400 gallon per hour maximum pumping rate and a 24 foot maximum head.
