  • Page 3: General Information

    GENERAL INFORMATION Thank you for your purchasing JEC products! This manual is a part of the JRZS series Twin Screw 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 JRZS series can be ordered with bare shaft, i.e. pumps without motor or common bed. Or, can be ordered as an ‘Integral type unit with B5 type motor' including integral adaptor, Common base and adjustable legs, motor cover & bracket. However, it can be changed optionally.
  • Page 5 Or, ordered as a ‘complete unit with B3 type drive motor, coupling & guard, common bed’ and layout described as below. Example Layout of pumps with complete unit ① Common bed, ② Drive unit, ③ Coupling & coupling guard, ④ Gearbox, ⑤...

  • Page 6: Packaging & Transport

    PACKAGING & TRANSPORT JRZS 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 7: 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 8: Warranty

    WARRANTY TERMS & CONDITIONS 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 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 a bad influence.

  • Page 10: Maintenance

    MAINTENANCE SCREW 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.
  • Page 11 Release wrench bolts on the screw case to be separated from gearbox. Fig. 5 If it is stuck tight, tap alternately on the rim of the screw case with soft hammer. Fig. 6 Slide along the stud bolt carefully and pull out the screw case from gearbox.

  • Page 12: Screw Case Assembly

    SCREW CASE ASSEMBLY Before installation for screw case to the gearbox, make sure to clean the surface of screw case and gearbox and check the shim plate surely between screw case and gearbox. Assembly can be done reverse way against the disassembling procedure. Slide and insert screw case along the stud bolt carefully to match the gearbox.
  • Page 13 Before insert the twin screws, interdigitate carefully and checking the key in screw and groove in shaft to be matched. Slide and insert carefully the twin screws to the screw case and treat carefully the screws to avoid damage. Fig. 14 Fasten screw bolts and spring washers with reference of below torque set value using wrench spanner.

  • Page 14: Screw Rote Clearance

    SCREW ROTOR CLEARANCE Screw rotor clearance must be precisely maintained to provide maximum pumping efficiency, yet prevent contact between screw rotors, screw 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 screw rotor clearances and adjust, if incorrect.

  • Page 15: Gearbox Maintenance

    GEARBOX MAINTENANCE Gearbox Disassembly 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 16 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 17 6. On the opposite shafts, interdigitate carefully for both screws together with checking the key and groove in shaft to be matched, and insert properly to the shaft shoulder. Fig. 25 7. Fasten the both screw bolts and insert ‘Feeler gauge’ with reference of below value to each series to secure screw timing.

  • Page 18: Integral Type Unit Assembly

    INTEGRAL TYPE UNIT ASSEMBLY If ZS series ordered by ‘Integral type unit’, they will be provided with pump head with integral adaptor, Common base with adjustable leg, motor, motor cover and bracket. However, the contents can be changed optionally. Seated the assembled pump head and integral adaptor on the Common base.

  • Page 19: 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 20: 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.

    * APPENDIX...

  • Page 63: 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 as: High temperature variations High pressure fluctuations Oil in gearbox is recommended to be changed once a year or every 2,000 operating hours.

  • Page 64: Power Lock Installation, Removal & Reusability

    POWER LOCK INSTALLATION, REMOVAL & REUSABILITY Installation 1. Verify that the saft and the inner surface of the hub are clean and lightly oiled. 2. Remove the bolths and clean all contact surfaces. Lightly coat the bolts including their surfaces with oil or grease.
  • Page 65 Removal 1. Verify that no torque or thrust is applied to the hub and shaft. Note that in cases where a heavy shaft, hub or chain is used, disassembly may be slightly complicated.
