Series 200 and 220 Pumps

Instruction Manual

The following is an excerpt from the Series 200/220 positive displacement rotary pump manual. For complete installation instructions, please download the full Series 200 & 220 Manual (PDF Download, 1.5 MB)

MODEL 200AV, 220TV VARIABLE VOLUME PUMP, 200AX, 220TX BYPASS HEAD PUMP, 200A, 220T SOLID HEAD PUMP, SERIES 200 AND 220 RATED 240 GPM@ 520 RPM

SERIES 200 AND 220 RATED 240 GPM @ 520 RPM.

PUTTING PUMP INTO SERVICE

CAUTION: When receiving a pump, carefully check for damage, broken port seals, and any misalignment incurred during shipping.

CORRECT 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.

SERIES 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.

SERIES 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.

MOUNTING AND ALIGNMENT

The following will cause misalignment:

  1. Warped base plate (correct by shimming pump and drive components)
  2. Pipe strain (correct by using hangers or appropriate pipe supports)

If pump is connected to drive member by couplings, shim components until coupling halves are aligned.

To prevent misalignment of pump and drive components, fasten base securely in place using the foundation bolt holes provided.

  • SHAFT 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.

DIRECT 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.

BELT 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.

OPEN GEAR 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.

PACKING GLAND

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 fitting provided.)
