However, some are designed to run off of 230V instead. Most sewage pumps are designed to operate off of a standard outlet. Instead, look for the GPM, or gallons per minute rating to find out the exact flow rate of a sewage pump this rating is more important than the horsepower. Although the pump motor is rated in horsepower, this does not tell you exactly how much water the pump moves. The higher the flow rate, the more powerful the sewage pump is. The power/flow rate of a sewage pump tells you exactly how much waste the pump can move. Though priced quite affordably, the 93501 sewage pump may not be the best long term investment. It also wouldn’t cover it if this had happened a few months further down the line. While the warranty covered it this time, it won’t cover the cost to repair the damage caused by flooding. In this case, it was within the one-year warranty time frame. Sadly, the float switch turns out to be a common weak link with this model. After discovering flooding, it was determined that the float switch was no good. Regrettably, this pump often dies before the three-year mark. It is capable of pumping water to a height of 25 feet maximum. While better than some models on the market, it’s one of the less powerful options on our reviews list. At 0.5 horsepower, it offers 80 GPM of water flow. The split-capacitor motor is thermally protected and built for continuous duty. The cast aluminum, non-clogging vortex impeller will easily handle two-inch solids. Superior pump offers an affordable alternative with some worthwhile features. Overall, we think this is the best sewage pump on the market you can buy today. Thankfully, the two-year warranty covers any such experiences. Second, some of these pumps seem to have been shipped with faulty gaskets from the factory that don’t properly seal. First, it’s at the higher end of the price range, though it does provide longevity and features to match. All that said, there are two things that hold this pump back. Even better, this pump also offers manual operation in the event of a switch failure or any other issue. The power cord features a quick-disconnect design that allows you to replace it in seconds without breaking the motor seals. Add a shut-off head of 25 feet and the ability to handle two-inch solids, and it’s clear that this is one of the best sewage grinder pumps available.
Further aiding in lengthening the lifespan of this pump are the permanently lubricated bearings and oil-filled, thermally protected motor. This efficiency helps translate to reduced energy costs and longer life expectancy. This efficient motor manages to produce a flow rate of 160 GPM on just 0.5 horsepower, making it very efficient. Commercial-grade durability for residential homes is the theme of the Liberty Pumps LE51A.
