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.

3 PUMP DESCRIPTION
3.1 Configurations
The WDX type pump is a horizontal, multistage,
radial split case, vaned diffuser type centrifugal pump
equipped with a special suction impeller for low
NPSH. It can be used with motor, steam turbine and
gasoline or diesel engine drives.
The WDX pumps are of modular construction with
identical stages being stacked axially to achieve the
desired pressure output. Four high strength external
tie rods connecting the two end casings hold them
together. A variety of optimal features and materials
allow it to fit a wide range of applications such as
boiler feed or reverse osmosis.
Various orientations for the radial suction and
discharge nozzles are allowed every 90° except
towards the bottom.
