  • Page 5 KERR TROUBLE SHOOTER GUIDE REASON OR SERVICE NEEDED Unusual pounding, knocking broken valve spring Insufficient fluid at high speed. Check to see if the suction line is the proper size and is not constricted, trash in line, valve partly opened, etc. There is also a possibility of gas in the fluid causing the roughness.
  • Page 6 INSTALLATION INSTRUCTIONS (SEE ILLUSTRATION) The importance of proper installation cannot be overstressed. As the reciprocating pump is almost unable to lift fluid, proper suction flooding is a must. This is the First step toward satisfactory operation. The Kerr Pumps Engineering Service will be happy to advise you in your installation problems. As almost every installation varies, you cannot exercise too much care in making certain your installation is proper.

  • Page 10 SERVICE PROCEDURES (ALL MODELS) 1. VALVES (Wing-guided type): A. Discharge Valves: The discharge valve and seat can be exposed by first removing the discharge valve cover cap. Once the discharge cover cap has been removed you may lift out the discharge valve spring and the discharge valve. The valve seat will be held in place by a taper fit and must be “pulled”...
  • Page 11 3. VALVES (Ball & Seat): In Kerr Pumps with block/billet type fluid-ends the valves are ball and seat design. These are exposed for removal/inspection by removal of the appropriate valve cover. The flat seats are kept in place by a screw-in valve retainer that can be best removed with a Kerr Valve Wrench made for the appropriate pump.
  • Page 12 When using the optional Kevlar or Teflon packing, be sure to rotate the “splits” so that none are “aligned” to insure that the packing holds properly. Normally, this packing is not lubricated and requires less tension on the stuffing box nut during operation.
  • Page 13 Corrosion may tend to seize the two components together making their separation difficult in some isolated cases. On models KP-3300, KT-3350/KT-3400 and R335/R340 the bolted in stuffing box assemblies must be removed prior to removal of the entire fluid end. They are held in place by four studs each. On all other units the stuffing boxes can be left intact.
