    Similar to the water jacket in every respect except for the pro- vision of corrosion-resistant tubing, heat exchangers, whether removable, or welded-on, are provided on Teikoku applications that require heating or cooling the fluid before it enters the rotor chamber. Heat exchangers are especially recommended for liquids with low specific heat characteristics.

  • Page 29: Appx A. Trc-1 Information Sheet

    The design of canned motor pumps is such that the rotating element cannot be seen while it is in operation. For this reason, Teikoku supplies an internal rotation indicator with a majority of our pumps. However, there are some instances where this device is not supplied, so we recommend purchasing the TRC-1.

  • Page 30: Appx. B. Troubleshooting

    Make sure pump is operating at design point and conditions specified Motor operating at overload condition. when purchased. Pump is operating below minimum flow. Increase flow through the pump. Pump is running dry. Check suction line for obstructions and closed valves Teikoku USA | Chempump Instruction Manual G-Series...
