What kind of sump pump will work in very high head applications of 75 feet or more?
The common well pump is an often-overlooked solution to pumping relatively clean water at discharge heads of more than 75 feet. There are many reasons you might want to pump water from a tank or a sump, including: for use as wash-down; for foam-reducing sprayers; for irrigation; or just for high vertical or long horizontal runs where the high head pressure required exceeds the capabilities of a normal single-stage sump or effluent pump.The common multistage submersible well pump is a perfect solution in these applications. For a relatively modest horsepower input you can easily get heads of over 200 feet. The one caution for using a well pump in an open pit or tank is that some type of flow inducer must be fitted around the motor for adequate cooling. Also, well pump motors come with only about a 2-foot power cable, so a waterproof splice will have to be made. Well pumps come in many different flow and pressure ranges, so contact our tech support department for proper sizing.
