Extensive Pump Overhaul

This pump provides water to over 100 apartments and we were called when the building maintenance manager noticed water leaking from the base of the pumps.

We identified the need to strip the pump down and with space restrictions and the weight of the pump it wasn't a decision taken lightly!

Using our gantry we removed the controls and motor. This left us with the rotating element to remove. This is usually a straight forward process but this thing was seized in there solid. Using the gantry, we lifted out the element and found the bottom casing and bearing cast had been eaten away by cavitation.

This was cause due to the previous company setting the pressure too high meaning the pump was trying to push out water quicker than it could pull in from the water tank causing a negative suction.

After we replaced all the damaged sections, we recommission the booster set to suit the building, lowering the pressure and losing the negative suction.
