  • Page 3: General Information

    GENERAL INFORMATION Thank you for your purchasing JEC products! This manual is a part of the JRZL series Rotary Lobe Pumps describes safe and appropriate operation during operating and in all life cycles. This contains instructions for installation, operation, disassembly and assembly, maintenance procedures, troubleshooting and a complete parts list for all.

  • Page 4: Construction

    CONSTRUCTION JRZL series Rotary Lobe Pumps can be ordered with bare shaft, i.e. pumps without motor or common bed. Or, ordered as a complete unit with drive motor, coupling & guard, common bed (or trolley) and layout described as below.

  • Page 5: Packaging & Transport

    PACKAGING & TRANSPORT JRZL series are shipped in non-returnable wooden packaging. Unpack the pump/unit upon delivery and inspect it for visible transport damage. Any damage occurred during the transporting has to be immediately reported to the transport agent after receipt of the consignment. Do not put the damaged products into operation.

  • Page 12: Warranty

    WARRANTY Terms, Warranty Provisions, Notice of Claims and Limitation of Liability All terms & conditions and prices of sale are based on the applicable JEC price list at the time an order from Customer is received by JEC and are subject to change without notice. No assignment of the purchaser’s rights may be made without consent of JEC.

  • Page 13: Safety

    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 service the pump while it is running. DO NOT place the pump in an application where the service ratings are exceeded. DO NOT modify the pump.

  • Page 14: Installation

    INSTALLATION INSTALLATION 1. Mounting surface should be flat and level. 2. Ensure at least 0.5m clearance around the pump. 3. Normally, pump and drive unit are configured with common bed. If you want other way, feel free to contact JEC. 4.

  • Page 15: Check Pump Rotation

    CHECK PUMP ROTATION PRINCIPLE OF OPERATION The pumps are of the positive displacement rotary type with lobed rotors. The volume at the inlet increases when the rotors rotate and the product is drawn into the pump. It is then transported in the space between the lobes and the periphery of the pump housing to the discharge side.

  • Page 16: Operation

    OPERATION 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.

  • Page 17: Cleaning

    CLEANING 1. Before cleaning the pump, wear rubber gloves and protective glasses. 2. While CIP and SIP process, do not touch the pump and pipelines. 3. Ensure velocity rate of CIP solutions is adequate to clean entire circuit. For most applications a velocity of 1.52 m/sec is sufficient.

  • Page 18: Maintenance

    MAINTENANCE ROTOR CASE DISASSEMBLY Prior to removal of pump, the shut-off valves in the suction and discharge pipe work must be closed. If there is any risk that product may be hardened, crystallized or frozen in the pump it should be thoroughly drained and cleaned immediately after use. Similar attention must be applied to the seal flushing system.

  • Page 19: Inspection

    After pulling out both rotors, rotor case can be separated by sliding along the stud bolt and pulling out from the Gearbox. Inspect the rotor case for wear, clean and continue to seal maintenance, if needed. Fig. 5 In this time, handle and place carefully to keep the right track of position of the top &...

  • Page 20: Seal Maintenance

    SEAL MAINTENANCE JRZL series is designed by ‘Front Loading Seal’ that the mechanical seal system can be changed or replaced without removing rotor case. Check & inspect all components of seal replacement kit carefully whether there is any damage or defect before installing.
  • Page 21 Single Mechanical Seal Maintenance Remove the Seal ring from the rotor case & rotor (shown in Figure 13) and inspect them. If any seal is damaged, do not re- use and replace it. Clean both shaft ends and the rotor case before assembling. Push the replacing NEW Seal ring into the rotor case O-ring and turn fit into the seal pins on the seal body after Rotor Case Assembly on page 16.
  • Page 22 Place the rotor case face down on the table and pull out carefully the Double seal body out of rotor case by hands shown in Figure 18. Lubricate the replacing double seal body or O-ring and insert it into the rotor case and fit into the Seal pin properly. See ‘Rotor Case Assembly’...

  • Page 23: Rotor Case Assembly

    ROTOR CASE ASSEMBLY Before installing the rotor case (31) to the gearbox (1A), make sure to clean the surface of rotor case and Gearbox and check the shim plates surely between rotor case and Gearbox as originally. Assemble the rotor case (31) onto the Gearbox (1A) and secure the four hexa-nuts (46) with reference of below torque set value.

  • Page 24: Rotor Clearance

    ROTOR CLEARANCE Rotor clearance must be precisely maintained to provide maximum pumping efficiency, yet prevent contact between rotors, rotor case, and front cover during operation. If pumping efficiency is lower than expected or if parts contact has occurred during operation (Within rated differential pressure), check the rotor clearances and adjust, if incorrect.

  • Page 25: Rotor Timing

    Rotor thickness and body depth are fixed at manufacturer. Therefore, with the correct rotor size selected, the only maintenance adjustment that can be made is the proportion of front and rear clearance. Measure the front clearance as follows: 1. The rotor to rotor housing back face clearance is maintained by the shim(s) (45). 2.
  • Page 26 6. If the rotor timing is correct, measure the gap of the gear between drive shaft and idle shaft using depth micrometer shown in Figure 28. Adjust the gap using spacer and shim(s) according to the below cases. * If the gap is (+) value (idle shaft is more embossed than drive shaft) as shown in Figure 29, combined 6mm spacer &...

  • Page 27: Gearbox Maintenance

    GEARBOX MAINTENANCE Gearbox Disassembly 1. Remove the drain plug and drain the oil. Remove the shaft key (7) on the drive shaft and Gearbox cover bolts (6) from the rear cover (4). Pull the cover off the drive shaft extension. If the cover stuck, use a soft mallet carefully to loosen it.
  • Page 28 Or pull out the drive & idle shafts by hitting with soft mallet the rear-end of each shaft on the gasket face of the Gearbox. Fig. 35 9. Remove the bearings and spacers (16) together from the shafts by pressing the shaft separated with them. Or remove bearings by puller shown in Figure 36.
  • Page 29 Gearbox Assembly 1. Clean and lubricate the front & rear bearing areas of the drive & idle shafts with oil. Fit the front bearing, spacer and rear bearing on the shaft sequentially by arbor press (or heat 120℃(250F) up by heater). Position the gearbox (1) with wet end side facing up and be sure to place carefully for the gasket face(downside) of cover during this time.
  • Page 30 4. Place the gear, lock washer (12) and lock nut (12-1) sequentially onto the shafts and hand tighten. In order to ensure proper rotor timing the gears must be installed along with the rotors. Slide the gears on the shafts aligning the slot on the gear with the gear key Fig.

  • Page 31: Lubrication

    Lubrication Pump bearings and gear should run in an oil bath. Replacement of these bearings and gear wheels is recommended after 20,000 hours of operation. However, the shorter change intervals required for particularly difficult operating conditions, such High temperature variations High pressure fluctuations Oil in Gearbox is recommended to be changed once a year or every 3,000 operating hours.
