Check whether it turns correctly.
To make sure all pipe lines are connected tightly and can supply water normally.
The valves in the inlet pipe line are completely opened and the outlet valve shall be opened slowly after
the pump is started up.
Check the operation pressure if pressure meter is installed.
Check all the controls for normal operation. If the pump is controlled by pressure switch, check and
adjust the starting pressure and stopping pressure. Check the full load current to make sure it not
surpasses the max. current.
4. Frequency of pump starts:
Pump should not be started too frequently. It is suggested pump shall not be
started more than 100 times per hour if the motor power is less or equal to 5 HP. When motor power is big
than 5 HP, pump shall not be started more than 20 times in one hour. If pump starts and stops too frequently,
control device shall be checked and adjusted to make pump not start and stop too frequently. Also, it is
necessary to check the installation.
5. Suggestion:
When pump running, flow should be controlled at the range of 0.5 - 1.3 times of rated flow.
6. Pump which is installed according to this installation manual will work effectively and require a
little maintenance.
Mechanical seal will be adjusted automatically, the moving part and stationary part is lubricated and
cooled by the transfering liquid. When replace the mechanical seal, the user don't need to disassemble
the motor for power bigger than 10 HP.
The bearing in pump is lubricated by the transfering liquid.
7. Frost Protecting.
Pump can be used in the system with anti-frozen measures to water. If the pump is
installed in easily frozen place, suitable antifreeze shall be added to the transfering liquid to prevent pump
from being damaged. If antifreeze is not used, pump shall be stopped when it is frozen. Pumps which are not
being used should be drained.
8. The following should be checked regularly for pump.
Pump working and operating pressure.
Possible leakage.
Possible motor overheat.
Cleaning / replacement of all strainers.
The switch off time of motor when overload.
Frequency of starts and stops.
All control operation.
If malfunction is found, check system according to
“Fault Finding & Solution Chart”.
9. Pump shall be cleaned and kept appropriately when it is not used for a long time.
l0. Pump shall be prevented from being corrupted and damaged in storage.
