Appendix G—Troubleshooting GuideIn diagnosing pump and system troubles, record thefollowing data during product transfers:1. Pressure at pump suction.2. Pressure at pump discharge.3. Pressure in truck tank.4. Pressure in tank being filled.5. Pipe size and length of suction and discharge lines.6. Size and length of vapor equalizing line.7. Pump speed if practical.Problem Cause SolutionLow capacity Pump speed too slow Check engine speed and PTO on pulley ratio. Consult pump performancecurve. Use tachometer on pump if speed is questionable.High differential pressureExternal bypass valvestuck open or set too lowClogged strainerSuction pipe too smallor restrictedRestriction in discharge piping or hose too small. Vaporequalization lines too small or not used.Readjust, repair, or replace valve.Clean strainer.Indicated by pump inlet pressure dropping several pounds whenpump is started. Remove restriction or modify piping.Worn vanesReplace.Pump without vapor return Without vapor equalization, a pump can remove only about 3%of the truck tank capacity per minute without severe cavitationand capacity loss.Worn sideplatesReverse or replace sideplates. Check universal drive assemblyto make sure angularity is within limits, yokes are parallel andslip-joint is greased. Check bearings. Check pulley alignmenton belt drive pumps.Vanes stickingRemove vanes and clean out foreign matter (checkstrainer). Replace vanes if swollen.Pump runs Valve closed Check valves. Make sure internal tank excess flow valve isbut no flowopen! Refer to manufacturer’s instructions.Excess flow valve slugged Stop pump until valve opens. If problem continues, slow pumpdown or install a new or larger excess flow valve.Broken shaftDisassemble and inspect pump. Repair if necessary.Defective meterService meter.Pump will not Foreign matter in pump Clean out the pump—check strainer in suction line.turn–locked upVanes brokenClean out pump carefully and replace vanes. Haspump been operated dry? Then, check for damage to cam androtor shaft assembly.Bearing seizedReplace pump bearings. Grease monthly. Use ball bearinggrease manufactured for intended service.Moisture frozen in pump Let thaw and break loose carefully. Add methanol to tank (onLP-Gas). Check with product supplier about possibility of waterin gas.Will not buildpressure Poor suction conditions Clean inlet strainer. Increase pipe size.External bypass valve Set valve for higher pressure—see instructions.set too lowSee IH102 and IH106 IOM manuals for more information.Worn vanesDisassemble, inspect and repair as necessary.

Do not run pump dry!Appendix H—Storage of theZ-Series Coro-Vane ® Truck PumpsIf your <strong>Corken</strong> Z-Series pump is to be removed from servicefor some time, the pump must be protected as propane,butane and anhydrous ammonia all leave the metal “bare”and open to corrosion. Piping and tanks not in service shouldalso be protected, as the rust particles can destroy thepump's seals almost immediately after startup.1 Fill or thoroughly flush the pump with a light rustinhibiting oil. (If the pump is flushed with oil, placingsome desicant packets inside the pump will provideadded protection.)2. Plug all pump openings.3. Store in a dry location.4. Before placing the pump back into service, drain the oiland remove any desicant packets.5.
