PUMP INTO SERVICE
When receiving a pump, carefully check for damage, broken port seals, and any misalignment incurred during shipping.
PIPING HOOK-UP: The series 200 and 220 pumps come with two 4" flanged ports designed for use with Schedule 40 steel pipe. Connect piping based on directions of shaft rotation.
200 CW (CLOCKWISE) Rotation pump has the suction port on the right side and discharge port on the top (viewed with shaft end toward you). Series 220 CW has top suction and left side discharge.
200 CCW (COUNTER CLOCKWISE)Rotation pump has the suction port on the left side and discharge port on top. Series 220 CCW has top suction and right side discharge. • Any pump may be run in reverse temporarily for such purposes as stripping lines, etc.
following will cause misalignment:
base plate (correct by shimming pump
and drive components)
strain (correct by using hangers or
appropriate pipe supports)
pump is connected to drive member by couplings,
shim components until coupling halves
prevent misalignment of pump and drive
components, fasten base securely in place
using the foundation bolt holes provided.
SHOULD ALWAYS BE TURNABLE BY HAND
- As a last check before starting pump: Remove gland nuts and slide packing gland out of housing. If gland does
not slide back into housing without interference, pump is misaligned.
MOTOR DRIVE UNITS
AND GEAR DRIVEN UNITS:
Abutting shafts must be at least 1/8 of an inch apart and coupling inserts and/or chains should be loose enough to prevent end thrust on pump shaft.
DRIVEN UNITS: An outboard bearing must be used to prevent side thrust on pump shaft. Pump shaft must be free to slide longitudinally through outboard bearing, so that rotor group will not be forced against pump case components. Align sheaves using straight edge or stretched cord.
DRIVEN UNITS: Proper alignment and engagement of gear and pinion can be checked by passing foil or cellophane through them. An outboard bearing should be used to prevent side thrust on pump shaft. Pump shaft must be free to slide longitudinally through outboard bearing so that rotor group will not be forced against pump case components. CAUTION: Use gear and pinion set of same pressure angle such as furnished by factory, otherwise fibre motor pinion life will be short.
The packing gland serves a dual function; first as packing follower and second as a bearing which, with the shaft
housing bushing, forms a support for the rotor and shaft. As shipped from the factory, the gland is LOOSE
ENOUGH TO BE ROCKED BY HAND. At first start-up DO NOT tighten gland until pump has run long enough for
packing to expand from absorption of pumpage. Thereafter, to adjust, tighten nuts evenly one-quarter turn at a
time, just enough to reduce leakage - NO MORE - a drop or two of the pumpage should normally drip from the
gland every few minutes (except of course with mechanical seals, or external scavenging systems). SHAFT
SHOULD ALWAYS BE TURNABLE BY HAND. (Keep shaft well lubricated with appropriate lubrication through
