KSB ETN Extended Coupling Single Stage End Suction Centrifugal Pump

Extended Coupling Single Stage End Suction Centrifugal Pump

Use/maintenance

The maximum ambient temperature of the water pump is 40℃.

In order to prevent the motor temperature from being too high, the maximum allowable number of start-stop times per hour for pumps under 11KW is 15 times, and the maximum allowable number of start-stop times per hour for pumps above 11KW is 6 times.

For grease lubricated water pump bearings and motor bearings with oil nozzles, grease should be replenished regularly every 4000 hours (about 6 months). 2# or 3# high temperature lithium base grease can be used.

For water pump bearings lubricated with thin oil, the oil needs to be changed after 300 hours of initial operation, and then every 3000 hours, and at least once a year.

After 24 hours of initial operation, the coupling alignment should be rechecked. Thereafter, it will be reviewed every 2000 hours (3 months).

When the medium temperature is -30℃~70℃, the minimum flow rate is greater than 15% of the rated flow rate; When the medium temperature is 70℃~140℃, the minimum flow rate is greater than 25% of the rated flow rate.

Stop the water pump for a long time, and start it regularly once a month for 1 minute each time.

When the water pump has been shut down for more than 3 months, it is necessary to manually loosen the pump shaft before starting, and then start it again after confirming that there is no sticking.

When the water pump is shut down for more than one year, replace all rubber seals.

Bearing temperature is not allowed to exceed 90℃.
