Operating Manual

Installation Instructions

1. Before installation, check whether all fasteners of the pump unit are tightened and ensure the pump chamber is free of foreign objects to avoid impeller or pump body damage during operation.
2. The weight of the pipeline must not be supported by the pump. Each pipeline section should have its own support to prevent pump deformation, which may affect performance and service life.
3. To prevent impurities from entering the pump and blocking the flow passage, install a filter in front of the pump inlet. The filter area should be 3–4 times larger than the suction pipe cross-sectional area.
4. When pumping hot liquids, to avoid thermal deformation transmitted from the pipeline to the pump, the pump base bolts may remain unfixed so that the pump can move together with the pipeline during thermal expansion and contraction.
5. For easy maintenance and safe operation, install regulating valves and pressure gauges at both the inlet and outlet of the pump to ensure operation within the rated performance range.

Maintenance and Service

1. Preparation Before Startup

1. Check whether the grounding of the canned motor and starting equipment is complete and reliable, and whether all wiring connections are correct.
2. For newly installed or long-idle canned motors, check the insulation resistance of the stator windings to ground before use.
3. The pipeline must be completely filled with liquid; otherwise, the motor service life will be affected.

2. Maintenance During Operation

1. Record the voltage regularly, including variations and unbalance. Overvoltage, undervoltage, or voltage unbalance may cause motor overheating and abnormal operation.
2. Record the pump load current and current unbalance regularly. Most pump failures manifest as abnormally high stator current, causing the motor to overheat.
3. Record the liquid temperature in the pipeline frequently to ensure it does not exceed the rated temperature on the nameplate, preventing long-term overheating.
4. Record inlet and outlet pressure gauge readings. The inlet pressure must not be lower than zero, and the pressure difference between outlet and inlet must meet rated values.
5. Before each use, exhaust air from the pump. During long-term operation, the pump must be vented once every week.
6. Monitor odors, vibration, and noise during operation. Overheated motor windings produce a burnt-insulation smell. Mechanical faults typically manifest as abnormal vibration or noise. Stop the pump immediately if abnormalities are detected.
7. Check the circulation path and filter of the cooling liquid regularly to ensure that no blockage occurs.
8. Periodically measure the clearance between the graphite bearing and the shaft sleeve to keep the gap uniform between the stator and rotor shielding sleeves. Exceeding the limits requires repair or replacement.

Allowable Bearing Clearance

Sleeve Diameter (mm)	Wear Limit Clearance (mm)	Standard Clearance (mm)
>18–30	0.40	0.131
>30–50	0.45	0.158
>50–80	0.50	0.192

9. Regularly check the clearance between the impeller wear ring and pump body. Excessive clearance affects pump performance. If the clearance exceeds 1.5 mm, replace the impeller. Under special conditions, repair techniques may be applied.

Operation & Running

1. Startup and Operation

1. Fill the pump completely with liquid and exhaust air. Open the inlet valve and loosen the vent valve on the top of the motor. Close the vent valve after air is fully discharged.
2. Close the outlet valve to reduce starting current.
3. Check all components to ensure they are functioning normally.
4. Switch on the power supply and confirm the correct rotation direction.
5. Gradually open the outlet valve to bring the pump to operation within the rated performance range.
6. If any abnormalities occur during operation, stop the pump immediately for inspection.
7. Check the motor current and temperature rise to ensure they comply with rated requirements.

2. Shutdown

1. Close the discharge valve.
2. Cut off power to stop the motor.
3. Close the inlet valve.
4. If the pump remains out of service for a long time, drain all liquid from the pump.
