Before starting pump, be sure
that any resulting machine function will not
endanger persons or equipment.
PRODUCT IDENTIFICATION
Each pump has a Model Code stamped on its
nameplate. See Figure 1 for the location of the
Model Code.
This service manual applies to products with Ordering
Codes like the sample in Figure 2.
INSTALLATION
NOTE THESE CHANGES:
Design Series
“A” thru “G” used a #406 woodruff key
nominally 1/8 inch (3.2 mm) wide. Design
Series “H” and later use a common 3/16 x 3/16 x 1
inch square key. When replacing older pumps with a
newer one, it will be necessary to either install a new
coupling half with a 3/16 inch keyway or machine the
existing keyway. Also, the pressure adjustment screw
is 3/4 inch (19.1 mm) longer. Check dimensions of
existing installation to make sure there is sufficient
clearance for the adjustment screw.
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. Direct inline through a jaw type/flexible web
coupling is recommended for all Continental 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 PVR1 pumps, or as the coupling manufacturer
specifies.
