IMPELLER ADJUSTMENTThe horizontal 1500 series design permits adjustmentof the impeller clearance between the pumpcasing wall and the impeller face. The pumpimpeller is adjusted at the factory during assemblyand should not require further adjustment uponinstallation.Impeller adjustment will be required when a dropin head and/or capacity indicates a change inclearance, or when existing components of thepump are replaced. Refer to the following table forrecommended clearance when adjusting impelleron horizontal pumps.Impeller DiameterClearanceUp to 8" .015”8" to 10" .020”10" to 16" .025”A) Loosen set screws or other holding devices ifso provided on mechanical seals before adjustingimpeller to prevent seal face damage.B) Loosen the adjusting screws (Item 33A) evenly.C) Tighten up equally on the screws that threadinto the power-frame until you can feel theimpeller just starting to rub on the casing face.By rotating the shaft frequently by hand whiletaking up on the screws, you can determinewhen the impeller begins to bind.D) Back out the screws that thread into the powerframeuntil you can insert a feeler gauge undereach of the bolt heads to the recommendedclearance (See table above).E) Tighten the remaining adjusting jacking screwsuntil the gap left by the feeler gauge is gone.F) Check to be sure the shaft turns freely.G) Reset and tighten the mechanical seal per theseal manufacturers instructions.NOTE: Frequent impeller adjustments torestore hydraulic performance are an indicationof increased internal clearances. Excessiveclearance behind the impeller will result inexcessive thrust loads in high pressure pumpsleading to reduced outboard bearing life.Replace worn parts.16
INSTALLATION INSTRUCTIONS WOOD’S COUPLINGSWARNING: DO NOT PROCEED WITH THECOUPLING INSTALLATION UNTIL THEDIRECTION OF MOTOR ROTATION HASBEEN ESTABLISHED TO BE CORRECT.FAILURE TO DO SO MAY RESULT INDAMAGE TO THE PUMP.1) Inspect all coupling components and removeany protective coatings or lubricants frombores, mating surfaces and fasteners. Removeany existing burrs, etc. from the shafts.2) Place four cap-screws with lock-washersthrough the holes in each spacer hub. Slideone spacer hub onto each shaft, usingsnug-fitting keys.3) If using a two-piece sleeve, assemble the twohalves together and hang the wire ring looselyin the groove next to the teeth.4) Position the sleeve between the two flanges.Be certain that the teeth on the sleeve are fullyseated in each flange.5) Place this assembly between the spacer hubs.Align the tapped holes in the flange with thecap-screws in one of the hubs. Hand tightenthese four cap-screws and visually inspect thegap between the hub and the flange to ensurethat the flange is seated properly. Tighten thefour cap-screws to their designated torquevalues, see table below.6) Rotate the other shaft until the cap-screws onthe other hub can be started into the tappedholes of the loose flange. Hand tighten thesefour cap-screws and visually inspect the gapbetween the hub and the flange to ensure thatthe flange is seated properly. Tighten the fourcap-screws to their designated torque values,see table below.7) Check to be certain that the sleeve is still fullyengaged in both flanges. Then slide the couplingassembly so that there is an equal lengthof shaft extending into each flange. Check thatthe shaft keys are fully engaged between theshaft and the hub before tightening the setscrewson both hubs. See the following tablefor torque values.TORQUE VALUES TYPE SC COUPLINGSCoupling Hub SizeCap-Screws (ft-lbs) Set-Screws (ft-lbs)3 — —4 5.5 135 4 136 9 137 9 138 18 239 31 2310 50 5011 75 5012 150 10013 150 16514 150 16516 150 1658) Check parallel alignment by placing a straightedgeacross the two couplingflanges and measuringthe maximum offset atvarious points around theperiphery of the couplingwithout rotating the coupling.If the maximum offsetexceeds the figure shown under “Parallel”in the following table, realign the shafts.9) Check angular alignment with a micrometeror caliper. Measure from the outside of oneflange to the outside of the other at intervalsaround the periphery ofthe coupling. Determinethe maximum and minimumdimensions withoutrotating the coupling. Thedifference between themaximum and minimummust not exceed the figure given under “Angular”in the following table . If a correction is necessary,be sure to recheck the parallel alignment.NOTE: KEEPING COUPLING MISALIGNMENTVALUES AS CLOSE TO ZERO AS POSSIBLEWILL EXTEND COUPLING LIFE ANDREDUCE VIBRATION LEVELS.17
