CDR Pompe Pump UCL 50-32-200 50 Hz

Measures to take for periods of long inactivity

Periodically start the pump for about five minutes (about once a month) to prevent sediment formation.

Did you run the pump for at least 5-10 minutes this month?

Running the pump after a long period of stop

Review the entire section 'Starting and stopping' and the section 'Maintenance' before restarting the pump.

Recommendations for pumps inactive up to one year

Additional recommendations for pumps inactive beyond one year

Fill the pump with inert gas when draining if electrically charged liquids were used.

Wait at least one hour before removing the pump from the plant to allow electrostatic charges to dissipate.

Verify the following conditions before proceeding

Use lubricant with viscosity of 46Cst

Is the pump installed in an environment with an explosion hazard?

Ensure no excessive increase in temperature is observed

Describe any unusual observations during the oil change

Verify the following conditions before proceeding

Use lubricant with viscosity of 46Cst

Is the pump installed in an environment with an explosion hazard?

Monitor the bearing temperature during operation

Check for excessive increase in temperature

Ensure pump unit undergoes proper maintenance at regular intervals

Consider working point of the pump referred to the characteristic curve

Consider circumstances such as intermittent operation, characteristics of the pumped fluid, and installation in a system

Check components that may impair pump operation if not replaced regularly

Is the bearing bracket over temperature?

Check the alignment of the elastic coupling between pump and motor

Ensure the following pre-start conditions are met

Is the suction pipe filled and foot valve working properly?

Verify motor and pump conditions

Is the liquid temperature maintained to prevent crystallization or solidification?

Is the oil level adequate for pumps with oil lubricated bearing bracket?

Ensure operating and functional parameters of the mechanical seal are followed
