PRODUCT IDENTIFICATION
Each pump has an Ordering Code stamped on its
nameplate. See Figure 1 above for the location of the
Ordering Code.
INSTALLATION
PUMP DRIVE AND MOUNTING
When mounting the pump and motor, care must be
taken to align the pump and motor shafts within .003
T.I.R. (0.076 mm) direct inline through a jaw type/
flexible web coupling. This is recommended for all
pumps. Tire-type flexing elements and chain-type
drives are not recommended. With belt drives, please
consult factory.
To avoid axial and radical end loading of the pump
shaft, do not couple the pump and motor shafts
rigidly. Allow freedom at the coupling for the two
shafts to ride independently.
To prevent end loading, the space between the pump
and motor shaft ends should be 1/2 inch (12.7 mm)
for PVR6 pumps, or as the coupling manufacturer
specifies.
