General
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.
Method of heating:
□
Fluid heating system
Fluid heating system
The fluid heating system consists of a heating system
241
attached additionally to the pump housing
through which a heating liquid (for example vapour, thermal oil) flows.
Operating data:
□
Maximum pressure: 16 bar
□
Maximum liquid temperature: 220 °C
Mounting the fluid heating system
Scope of delivery:
1. Mount the heating cover to the pump housing using the supplied socket screws.
2. Mount the piping.
Commissioning the fluid heating system
Required heating-up period for the temperature difference of 20 °C or 50 °C at a liquid temperature of
200 °C see Fig. 1, page 8:
Tab. 1 Heating-up periods for fluid heating system (values apply for pumps without thermal insulation)
► Observe the permissible operating limits of the pump when setting the supplied mass flow and its
temperature, see Tab. 1, page 7.

WARNING
Danger of the pump housing bursting and danger of injury through emitted pumped liquid through the
heat expansion of the pumped liquid.
► Open all the valves during the heating process.
