2.4 Storage
Store the pump in a clean, dry
location away from vibration. Leave piping
connection covers in place to keep dirt and other
foreign material out of pump casing. Turn pump at
intervals to prevent brinelling of the bearings and the
seal faces, if fitted, from sticking.
Do not store pumps starting on the fan guard.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.

The MEN pump is a single-stage centrifugal pump
with an axial inlet and a vertical outlet. The
dimensions of the volute pump casing, of the suction
and discharge diameters, of the settlement feet as
