  • Page 3: General Information

    GENERAL GENERAL INFORMATION Thank you for your purchasing JEC products! This manual is a part of the JRZP series Circumferential Piston 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 JRZP series Circumferential Piston 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. Example Layout of pumps with complete unit ①...

  • Page 5: Packaging & Transport

    PACKAGING & TRANSPORT JRZP 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. The pumps need to be transported and secured with care to ensure no damage caused.

  • Page 6: 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 7: 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 8: 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 9: 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.
  • Page 10 Clean and examine all of the pump components for damage. Replace damaged components as required. JEC recommends replacing all the wetted elastomers during reassembly. If you want to replace the seal ring only, you can remove the old one & insert the new one easily just after removing rotors without dismantling rotor case.

  • Page 11: Inspection

    INSPECTION While performing standard maintenance or cleaning, check for signs of damage or extreme wear. A simple inspection may show signs of a problem long before it becomes serious. Detection of such problems can avoid costly repairs and reduce down time. 1.

  • Page 12: Seal Maintenance

    SEAL MAINTENANCE JRZP 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 13 Single Mechanical Seal Maintenance Remove the Seal ring from the rotor case & rotor 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 Fig.
  • Page 14 Double Mechanical Seal Maintenance Remove the Seal ring from the rotor case & rotor (shown in Figure 19) 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 15.
  • Page 15 Triple Lip Seal Maintenance After removing rotor case (‘Page 9 & 10’), pull out and remove Ceramic coated sleeves from the shaft and inspect them. If any of them is damaged, do not re-use and replace it. Clean both shaft ends and the rotor case before assembling. Slide &...

  • Page 16: 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 & 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 value.
  • Page 17 Insert rotors along the shaft carefully without seal ring separated from rotor as Figure 30. Fig. 30 Tighten rotor bolts with the rotor bolt extraction tool firmly. Be sure not to make any bur on the rotor bolt groove during this process.
  • Page 18 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 19 Rotor Timing Rotor timing is critical for the pump operation and 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.
  • Page 20 Above cases of combinations (5mm & 6mm spacer, 0.1mm shim(s)) can be applied for ZP015 & 030 series only. While the other bigger size of shim(s) & spacer combination, but same concept, can be applied for ZP060 & 130 series. Fig.

  • Page 21: 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 22 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. 42 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 43.
  • Page 23 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 24 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 25: 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 26: 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 52: 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.
