Maintenance - Cala CA300M Installation And Maintenance Manual

5.

MAINTENANCE

• If the pump stops, check that the motor amp consumption during his working is the same or
less than that indicated on the manufacturer's specification board, or failing him, contact the
nearest Customer Technical Service.
• Empty the pump in cases where it must remain without use for some time, mainly in cold
countries where there may be danger of freezing.
• To empty the pump, remove the draining plug from the pump body (see explosion drawing).
• The pump components which, due to its regular use, suffer wear and tear must be periodically
replaced in order to maintain a good performance of the pump.
The following table provides a list of fungible pump components and/or components that can
be damaged and their estimated lifetime.
COMPONENT DESCRIPTION
O-rings and sealing elements in general
mechanical seal
Ball bearings
The estimated period of life of the parts above has been established under normal conditions
of product installation.
Follow the instructions in the manual in order to maintain the estimated lifetime of the pump.
6. DISMANTLING
• The motor unit may be dismantled from the pump body without needing to disconnect the
pump's suction and impulsion tubing.
• To disconnect the motor unit from the pump body, remove the screws that join them (see
explosion drawing).
