Zoeller sump pumps are built to last a long time when it comes to the housing and motor. A gentleman in Kentucky had his for 40 years. The cast iron used is profession grade class 25-30 25000# tensile strength. This is very evident when the weight of Zoeller pumps is compared to other cast iron pump brands. Cast iron is used for the motor housing. Cast iron dissipates the heat well so the motor lasts longer.
Zoeller motors never run at full capacity even during continuous operation. Zoeller does not use canned motors (those which are purchased from a third party, placed in a steel housing and then dropped into the pump housing. The steel gets very hot during continuous pumping and cases the motor to get even hotter ); instead Zoeller's motors touch the cast iron housing; they do not have an extra layer of steel around them thus the motors remain cooler. This leads to longer motor life.
The following video explains why Zoeller uses cast iron.
The seals are very permanent. The shaft seal is carbon and ceramic. The motor is hermetically sealed. A Watertight, neoprene square ring is inserted between motor and pump housing.
Though the following video shows how the Zoeller sewage pump is made, there is a lot of similarity between it and the submersible sump pump. Watching it will give you a real appreciation of the effort that goes in to assembly and testing.
The Zoeller M53 is made so well it is much better to replace worn parts than to discard the well-built pump. The parts that need replacement most frequently are the switch and the gasket. The switch should be replaced every three to seven years depending upon pump usage. The gasket needs replacement when the pump gives a gurgling sound and seems to lag in shutting off. This indicates that moisture is getting into the switch area. The moisture will cause failure. Both parts are easy to purchase, easy to install and very reasonably priced.
