  • Page 26 Caution Pump repair beyond the range specified in this instruction manual: Do not try to disassemble or repair the pumps by yourself. * The pump must be repaired by trained and qualified operators only. When it needs to be disassembled and repaired, stop operation and contact the supplier for advice.

  • Page 27: Installation

    * The lift head depends upon the liquid properties, temperature, and length of the suction piping. For details of the setup, consult Iwaki or your dealer. [2] Indoor and outdoor use The pump can be operated either indoors or outdoors. However, safety measures should be taken so as not to expose the motor and power distribution unit to flooding or other natural hazards.

  • Page 28: Piping

    [1] The area for anchoring the pump must be greater than the Foundation bolt area of the base. If the anchoring area is not enough, the Baseplate Liner base may be destroyed due to a concentrated load on it. Liner Concrete foundation [2] If pump operation is to be subject to vibration (resonance with the piping, for example), provide an expansion joint between the pump and the piping.
  • Page 29 ■ General precautions (1) All piping should be supported independently so that unnecessary weight and vibration are not transmitted directly to the pump. Expansion joint is recommended to avoid damaging the pump head especially. (2) The best piping arrangement for minimum loss is based on straight runs with as few bends and fittings as possible.

Wiring Electrical connections caution caution ATTENTION Caution Caution Caution Caution Electrical Electrical Shock Shock The electrical connection should be carried out by an authorized electrician in accordance with local regulations. Please make sure that the electrical data on the nameplate of the motor correspond to the electricity supply on which it will be used.
  • Page 31 ■ Preparation for start-up Preparations should be made, as described below, in the case of initial operation after installation and in the case of restarting of operation after a long period of inactivity. [1] Thoroughly clean the inside of the tank and pipe. Then, supply liquid. [2] Tighten the flange connecting bolts and the installation bolts on the base.
  • Page 32 [4] Continue to run the pump for 30 minutes or longer to let it warm up. Check that no abnormality is found. This procedure is necessary only during at the first operation, but when the ambient temperature is extremely low, continue no-load running until the oil temperature rises sufficiently because the motor may sometimes be overloaded a little due to an increase in the viscosity of oil in the drive unit.
  • Page 33 ■ Before a long period of stoppage 1. Solution in the discharge line may be under pressure. Release the pressure from the discharge line before discon- necting plumbing or disassembly of the pump to avoid solution spray. 2. Flush the inside of the pump and pipework with clean water or cleaning liquid. 3.

Check that specified oil is used. Check oil quantity and stain. Replenish or replace if necessary. Defect of oil seal or O-ring Replace.

  • Page 37: Maintenance And Inspection

    When inspection, overhauling, or repair work is necessary, stop the pump operation and contact the supplier. The overhauling and repair work for Iwaki pumps must be performed by qualified personnel who have been trained and certified by the pump supplier. User's failure to observe this instruction exempts Iwaki from the responsibility for personal injury or damage to the equipment or facility which result from its misuse.

    4. Disassembly and Assembly Refer to exploded view of the model corresponding to your pump. The views are shown on "name of parts." Caution • Before disassembling/assembling the pump, do not fail to turn off the main power supply. Display a board "WORKING" near the power switch to let other personnel know the situation.
  • Page 40 2. Diaphragm (1) Loosen the hex. head bolts (20). Loosen the hex. socket bolts (20), if any. (2) Remove the pump head (1). (3) Connect power supply and run the motor temporarily. Set stroke length to 100%. Turn off when the diaphragm comes to the top dead point.
  • Page 41 (3) When installing a LK-F 11, 21, 22, 31, or 32 flange (VC, VH, or VS type), use a spanner to fix the adapter (6) then fasten the nut (50) by hand. 2. Diaphragm (1) Connect power supply and run the motor temporarily, and move the diaphragm to the bottom dead point where the diaphragm is fully drawn back.
