Products Description
The vertical sewage pump is easy to install and has a wide range of applications. It can be used as a general pipeline pump for pressurized water supply in high-rise buildings, as well as for transporting sewage containing granular fibers. In addition to sewage transportation, it is also suitable as a drainage pump, filtration flushing pump, condensation circulation pump, etc.
The vertical sewage pump is mainly composed of components such as the shaft, bearing frame, pump cover, impeller, pump seat, motor bracket, and motor. It is a vertical, single-stage, single-suction vortex shell pump, and the impeller features a dual-channel structure, which can effectively handle fiber materials with a diameter up to 5 times the pump diameter, as well as solid particles with a diameter up to 50 mm.
Structural Features
Compactness: The vertical in-line centrifugal pump uses a vertically arranged structure, with the pump body and motor mounted on a single base. This results in a compact footprint, making it ideal for installation in limited spaces.
Stability: Since the inlet and outlet pipes are directly connected, no additional pipe connections or supports are required, simplifying installation and maintenance.
Operating Principle
The motor drives the centrifugal pump's impeller at high speed. Liquid is drawn into the center of the impeller and then ejected by centrifugal force. During this process, the liquid's kinetic energy is converted into pressure energy, enabling liquid transport.

Common faults and troubleshooting methods
|
Fault |
Cause |
Troubleshooting |
|
The pump does not produce water or the flow rate is insufficient |
1. Motor reversal 2. Impeller channel blockage 3. The head of the device is too high 4. Excessive resistance in the pipeline |
1. Swap the phase sequence of the two-phase power supply 2. Eliminate clutter 3. Use a high lift pump or reduce the head of the device 4. Reduce pipeline bends and increase the diameter of long pipelines |
|
Insufficient head |
1. Gas mixed in the medium 2. The impeller is severely worn |
1. Eliminate gas 2. Replace |
|
Exhale pressure, with large fluctuations |
1. The liquid level in the suction tank is too low 2. The suction bend pipe is not tightly sealed, causing the pump to malfunction Inhale air 3. High medium temperature |
1. Control the minimum liquid level of the suction tank 2. Check the sealing gasket and eliminate the problem of air leakage 3. Reduce the temperature of the medium; If the temperature of the medium cannot be lowered, increase the minimum liquid level in the suction tank |
|
Excessive power |
1. The flow rate is too large, exceeding the use range 2. The medium density is too high 3. Mechanical friction is generated |
1. Close the valve 2. Dilute the medium; if the medium cannot be diluted, close the valve 3. Perform maintenance and adjustment to eliminate friction |
|
Bearing heating |
1. Bearing wear 2. Too little or too much bearing grease 3. Bearing oil or grease deterioration |
1. Replace the bearing 2. The amount of grease filled should be 1/3 to 1/2 of the inner gap of the bearing, fill more for low speed and less for high speed 3. Change oil or grease |
|
The pump makes noise or vibrates |
1. There is gas in the medium 2. Impeller wear causes rotor imbalance 3. Bearing damage 4. Pump outlet suddenly shrinks 5. The suction elbow is not sealed tightly, causing the pump to inhale air 6. The suction tank liquid level is too low 7. The medium temperature is high |
1. Exhaust gas 2. Replace impeller 3. Replace 4. Use the same diameter delivery pipeline as much as possible, otherwise the pipeline should be far away from the pump outlet 5. Check the gasket and eliminate the leakage problem 6. Control the minimum liquid level of the suction pool 7. Reduce the medium temperature; if the medium temperature cannot be reduced, then Increase the minimum liquid level of the suction pool |
Feature
Safe and reliable, reducing maintenance costs: The balanced rotor components and reasonable bearing arrangement effectively balance the radial and axial forces of the pump, ensuring long-term stable operation with low vibration and noise.
Strong flow capacity: The smooth, large-flow channel and special impeller anti-blocking design ensure the pump operates without blockage.
Double sealing and double protection: The dual mechanical seals are configured in series to provide true dual protection and ensure the safety of the motor.
Application
The sewage pump is suitable for discharging severely polluted wastewater from factories and commercial areas, sewage discharge stations in major residential areas, water distribution systems in urban sewage treatment plants, drainage stations in civil air defense systems, water supply equipment in waterworks, sewage discharge in hospitals and hotels, municipal engineering construction sites, mining support machinery, rural biogas digesters, farmland irrigation, and other industries. It can also be used for conveying granular sewage and pollutants, as well as for clean water and weakly corrosive media.
