    Contents Thank you for purchasing JEC Products! This manual contains installation, operation, disassembly and assembly instructions, maintenance procedures, troubleshooting and a complete parts list for all JP series Centrifugal Pumps designed and manufactured by JEC Ltd. South Korea. READ THIS MANUAL carefully to learn how to service these pumps. Failure to do so could result in person injury or equipment damage.

  • Page 8: Ce (Declaration Of Conformity)

    SAFETY DO’S & DON’TS DO read and understand these instructions before installing or using the pump. DO use JEC spare parts when replacing a component of the pump. DO NOT services the pump while it is running. DO NOT place the pump in an application where the service ratings are exceed. DO NOT modifies the pump.

  • Page 9: Installation

    INSTALLATION INSTALLATION 1. Mounting surface should be flat and level. 2. The suction line should be kept as short as possible and present minimum friction loss. 3. Suction and discharge lines must be fully supported and installed so that no expansion or shock forces act on the pump which could lead to distortion.

  • Page 10: Troubleshooting

    TROUBLESHOOTING Problem Cause Solution Pump not turning Interruption of electrical power. Reset circuit breaker, check fuses. Key sheared or missing. Replace. Coupler or belts are not connected. Replace or adjust. Pump shaft or gears sheared. Replace. Wrong rotation. Reverse. Relief valve not properly adjusted. Adjust valve.

  • Page 11: Maintenance

    MAINTENANCE PUMP HOUSING DISASSEMBLY This JRZLF series with front bearing cover high pressure application has a same design and structure with JRZL series, except bearing applied front cover. Therefore, except the maintenance for front cover side, all of procedure is same as standard rotary pump.
  • Page 12 Note: JRZLF series has different screw thread for drive and idle shafts. (but ZL series has same screw thread for CW: tightening, CCW: loosening) The standard screw thread is CCW for loosening, and CW for tightening for drive shaft. But please check pump specification before maintenance because based on flow direction, extended shaft thread could be changed too.
  • Page 13 Remove the four stud bolt securing the pump housing to the gearbox. Figure 7 Figure 8 Slide the pump housing away from the gear box. In this time, handle the shim(s) with care to avoid lost and damage. If the housing is stuck, alternately tap on the back of the inlet and outlet ports with a soft hammer.

  • Page 14: Inspection

    If you want replace the seal ring only, you can ease dismantle pull it off from pump housing just after removed rotors without dismantle the pump housing. And new one pushes in to pump housing. The seal ring can be easily removed from rotor with small screw driver (-) or a pin as shown in Figure 13.

  • Page 15: Seal Assembly

    Seal Assembly Inspect each piece of your seal replacement kit for damage before installing them. Place the pump housing face down on a table, put new seal in to the pump housing and bolts tighten. (Figure 16, 17) Figure 16 Figure 17 Pump Housing Assembly Before install the pump housing to the gearbox make sure that cleaning on the surface of...

  • Page 16: Rotor Clearance

    Rotor Clearance Rotor clearance must be precisely maintained to provide maximum pumping efficiency, yet prevent contact between rotors, rotor housing, and front cover during operation. If pumping efficiency is below expectations, or if parts contact has occurred during operation (Within rated differential pressure), check, rotor clearances and adjust if incorrect.

  • Page 17: Rotor Timing

    Rotor Timing Rotor timing must be precisely maintained to provide maximum pumping efficiency, yet prevent contact between rotors during operation. If pumping efficiency is below expectations, or if rotors contact during operation (within rated differential pressure), check rotor timing and adjust if incorrect. Also check rotor timing after any gearbox dismantling when the gears are removed and/or replaced.

  • Page 18: Shaft And Bearing Replacement

    Shaft and Bearing Replacement Gearbox Disassembly 1. Remove the oil drain plug and drain the oil. 2. Remove the gear box cover bolts (33) from the gear box cover (2). 3. Pull the gear box cover off the drive shaft extension. If the cover stuck use a soft hammer carefully to loosen it.
  • Page 19 Gearbox Assembly 1. Clean and lubricate the front and rear bearing areas of the drive and idle shafts with oil. 2. Fit the front bearing, spacer and rear bearing on the shaft by arbor press or heat 120C (250F) up by heater. 3.
