Page 8: General
General General Heating The pump CLC 55 can optionally be equipped with a heating system (CLC 550 on request). The manu- facturer recommends heating systems for high-viscosity liquids that do not flow sufficiently if not heated. High viscosity can result in excessive power consumption or to problems arising through cavitation or sealing. -

The design with outside bearings does not come into contact with liquid and is therefore especially suita- ble for pumped liquids that harden when they cool down, tend to crystallize or are abrasive.

Page 16: Connecting The Pump To The Pipe System
Installation Connecting the pump to the pipe system CAUTION Damage to device or impaired functionality through mechanical stresses. ► Ensure that the pump mounting on the pipe system is free of mechanical stress. 1. Turn the pump shaft or fan impeller of the motor so that smooth running of the pump is checked. If the pump cannot be turned by hand, remedy the fault before installing the pump, see "Trou- bleshooting", page 32. -
Page 17: Connecting The Motor
Connecting the motor CAUTION Incorrect alignment of the shaft coupling causes noise, vibrations and damage to the coupling and bearing. ► After the mounting check the alignment of the coupling. 1. Check the linear offset of the coupling using a slide gauge or feeler gauge. If the limit values of the above table are exceeded, loosen the fastening of the pump or motor and move the pump or motor in order to adjust the linear offset. -

Page 24: During Operation
During operation 1. Switch on the pump. The pump delivers when the pressure on the pressure side of the pump rises or a flow indicator at the system side triggers. 2. If the pump does not deliver after 10 – 15 seconds of operation, abort commissioning, establish the cause of the fault and only then continue the commissioning procedure. -
