PRODUCT IDENTIFICATION
Each pump has an Ordering Code stamped on its
nameplate. See below for the location of the Ordering
Code.
This service manual applies to products with Ordering
Codes like the sample below.
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 3/4 inch (19.05 mm)
for PVR15 pumps, or as the coupling manufacturer
specifies.
PIPING AND RESERVOIR
The pump should be mounted with a minimum
number of elbows or fittings. The pump suction
should be at least 1-1/4 inch (31.75 mm) tube/pipe for
PVR15 pumps.
For any system and combination of piping except
High Water Based Fluids (HWBF), the vacuum at the
pump inlet must not exceed seven inches of Mercury,
(5 inch Hg. for fire resistant fluids). HWBF Pumps are
to have a positive inlet head in the range of 0.5-inch
Hg. to 20 inch Hg.
