CHANGING MECHANICAL SEAL COOLING OIL
Changing the seal oil in the KZE Series pumps is very easy.
1) Disconnect the pump power cable from the power source.
2) Pull the pump from the sump and lay it on its side as shown in the illustration
below.
3) Remove the oil fill/drain screw, and drain the oil contents into a catch
container. If there was water or the oil appeared milky, the mechanical seal
should be inspected and possibly changed.
4) Place the pump back into an upright position.
5) Fill the proper and type of oil back into the seal chamber.
