4.0 Maintenance
BEFORE ANY MAINTENANCE TAKE PLACE: TURN OFF POWER SUPPLY TO THE MOTOR.
4.1 Clean In Place, CIP
The pump can be manually cleaned or by Cleaned In Place (CIP). The following is an example of suggested CIP procedure. How-
ever, specific advice for each application can be obtained from your pump supplier.
If the temperature difference between the process liquid, or the pump, and the cleaning media is greater than 100º C (180º F), stop
the pump and then introduce the cleaning liquid. If the liquid is not gravity fed and the pump must draw the liquid from a supply
vessel, run the pump until it is filled and then stop. Allow the pump to adjust to the cleaning liquid temperature and then continue
running the pump at normal speed. If the pump has double mechanical seals, they must be continued to be flushed during the CIP
process. The length of time necessary to clean the pump and the type of liquid used is dependent on the type of process liquid and
its characteristics.
Never touch the pump or the pipelines as they can be extremely hot.
Always use rubber gloves and protective goggles if handling caustic substances.
The rotors and shaft seals in the pump have been selected for specific temperature and pressure conditions. Ver -
ify with UNIBLOC-PUMP or the documentation supplied with the pump that the operating parameters are not
exceeded.
Always rinse well with clean water after using cleaning agent.
4.2 Steam In Place, SIP
The pump can be manually cleaned or cleaned with Steam In Place (SIP). Following is an example of suggested SIP procedure.
However, specific advice for each application can be obtained from your pump supplier.
Stop the pump and introduce steam into the system. If the pump must be operated, allow it to adjust to the steam temperature and
then run it between 50-100 rpm. If the pump has double mechanical seals, they must be continued to be flushed during the SIP
process. The length of time necessary to steam the pump is dependent on the type of process liquid used and its characteristics.
After the SIP process is complete, allow the pump to return to ambient temperature or to the temperature of the process liquid.
Resume normal operation to remove condensate or to begin pumping another media.
Never touch the pump or the pipelines as they can be extremely hot.
Always use rubber gloves and protective goggles if handling caustic substances.
The rotors and shaft seals in the pump have been selected for specific temperature and pressure conditions. Ver -
ify with UNIBLOC-PUMP or the documentation supplied with the pump that the operating parameters are not
exceeded.
Always rinse well with clean water after using cleaning agent.
