About the MCP5537 Diaphragm Water Pump

Generac Mobile Products diaphragm pumps are a durable and reliable solution for removing water in a variety of shallow and muddy applications, including ponds, trenches, ditches and foundations. Diaphragm pumps don't have an impeller shaft or seal that can be damaged by sand or silt. And, because they are self-priming, these pumps will keep running “run dry” even after all water has been removed…then continue pumping when water pools up again. Available in 2 in. (50.8 mm) and 3 in. (76.2 mm) diameter pumps, in gas, electric and diesel engine models. Choose from skid-mount (S) or wheel mount (W).
