Horizontal Split-Case Pump Troubleshooting Guide and Solutions
|
No. |
Fault |
Cause |
Solution |
|
1 |
The water pump fails to draw water, and the pointers on both the pressure gauge and the vacuum gauge are fluctuating violently. |
Insufficient water has been primed into the pump, or there are air leaks in the piping and instrumentation. |
Add more water to prime the pump, and tighten the connections to seal any leaks. |
|
2 |
The water pump fails to draw water, and the vacuum gauge indicates a high vacuum. |
The foot valve has failed to open or is clogged; the suction pipe resistance is excessive; or the suction lift is too high. |
Replace the foot valve; clean or replace the suction pipe; or reduce the suction lift. |
|
3 |
The pressure gauge indicates that the pump is generating discharge pressure; however, no water is flowing from the pipe. |
Possible causes include excessive resistance in the discharge pipe, incorrect impeller rotation direction, a clogged impeller, or insufficient pump speed. |
Remedial actions: Inspect or shorten the water pipe; inspect the motor; disconnect the pipe fittings to clean the impeller; and increase the rotational speed of the pump shaft. |
|
4 |
Insufficient flow rate or insufficient head. |
Pump clogged; double-suction seal ring excessively worn; rotational speed insufficient. |
Clean the pump and piping; replace the double-suction seal ring; increase the rotational speed of the pump shaft. |
|
5 |
The water pump is consuming excessive horsepower. |
The packing gland is overtightened, causing the stuffing box to overheat; alternatively, the impeller may be worn out, resulting in an increased water discharge rate. |
Loosen the packing gland (or remove the packing and trim it down slightly), replace the impeller, and increase the resistance in the discharge piping to reduce the flow rate. |
|
6 |
Abnormal Internal Pump Noise; Pump Fails to Draw Water |
Excessive flow rate; excessive resistance within the suction pipe; excessive suction lift; air leakage at the suction inlet; or the temperature of the pumped liquid is excessively high. |
Increase resistance in the discharge pipe to reduce the flow rate; inspect the pump's suction pipe; check the foot valve; reduce the suction lift; tighten connections to seal any air leaks; lower the temperature of the liquid; or reduce the suction lift. |
|
7 |
Pump vibration. |
The pump shaft and motor shaft are not aligned on the same centerline. |
Align the centerlines of the pump and the motor. |
|
8 |
Bearing Overheating |
Lack of oil; the water pump shaft and motor shaft are misaligned; the oil ring is not rotating. |
Add oil. Align the shaft centerlines; inspect or clean the bearing housing. |

FAQ
Q: How to select the right material for the pump?
A: The material selection depends on the fluid characteristics, such as corrosiveness, temperature, and presence of solids.
- For clean water: Cast iron is usually sufficient
- For corrosive media: Stainless steel (SS304/SS316) is recommended
- For seawater or chemicals: Duplex stainless steel or special alloys may be required
Our engineering team can recommend the most suitable material based on your specific application.
Q: How to calculate the required motor power?
A: Motor power is determined based on flow rate, head, efficiency, and fluid properties. The general formula is:
Power (kW) = (Flow × Head × Density) / (367 × Efficiency)
To ensure accuracy and a safety margin, we will:
- Analyze your working conditions
- Consider system losses
- Match the most suitable motor (including voltage and frequency)
We strongly recommend contacting our team for precise motor selection.
Q: Do you provide technical support and customized solutions?
A: Yes, we provide full technical support and customization services. This includes:
- Pump model selection
- Motor matching (voltage, frequency, brand)
- Flange standards (DIN, ANSI, etc.)
- Material customization
- Performance optimization
We can tailor solutions based on your project requirements and local standards.
Q: What information is needed to select a suitable pump model?
A: To recommend the right model, we typically need:
- Flow rate (m³/h)
- Head (m)
- Liquid type and temperature
- Installation conditions
- Power supply details
Providing detailed information helps us ensure optimal performance and reliability.
Q: What is the maintenance requirement for horizontal split case pumps?
A: These pumps are designed for easy maintenance due to the split casing structure. Routine maintenance includes:
- Checking bearings and lubrication
- Inspecting seals and wear parts
- Monitoring vibration and noise
With proper maintenance, the pump can achieve a long service life and stable operation.
Q: What is your typical delivery time and packaging method?
A: Delivery time depends on specifications and customization level, usually ranging from 2–6 weeks.
