Servicing a Grundfos Vertical Multistage Pump

A Grundfos Vertical Multistage Pump is rather well designed. The pump mid section is well protected with stainless steel cover, with future after sales service in mind.

There are chances of water leakage at the intersection of Motor shaft and pump shaft. This is due to wear and tear of the mechanical seal that has the function of isolating water from the motor shaft while rotating.

Grundfos designed mechanical seals are also called cartridge seals and it is very easy to replace not to mention very cost effective as well. This pump usually has a life cycle of 10 years and more, until it’s housing of rotary shaft and impellers are completely corroded, the pump continues to supply a steady stream of water with desired pressure.
