Product Overview
The TSWA Series Horizontal Low-Speed Multistage Clean Water Pump is designed for transporting clean water and liquids with physical and chemical properties similar to water, and without solid particles.
It is primarily used in high-pressure water supply, high-rise building water supply, and industrial or mining drainage applications.
The pump’s flow range is from 10–155 m³/h, with a head range of 15–300 meters, and motor power ranging from 2.2–200 kilowatts. The nominal inlet/outlet size is between 50–150 mm, with a maximum liquid temperature of 80°C.
Model Designation
Key Features
-
Compact Design: The pump body adopts a compact design, occupying less space, making it suitable for high-rise buildings and industrial applications.
-
Low Noise and Low Vibration: Optimized hydraulic design and bearing configuration ensure the pump operates with low noise and low vibration.
-
Wide Applicability: Suitable for various clean water, hot water, high-temperature fluids, corrosive liquids, and petroleum products.
-
Easy to Maintain: The optimized structural design and removable components simplify the maintenance process.
Engineering Overview
The TSWA Pump adopts a horizontal multistage sectional structure, achieving high head performance through staged pressure accumulation.
The pump can precisely match the required flow and head conditions by selecting the appropriate number of stages and nozzle diameter.
It comes with a standard transverse suction and vertical discharge design, allowing for efficient integration into piping systems.
The pump and motor are mounted on a common cast iron base and connected through an elastic coupling, ensuring stable torque transmission and continuous operation.

Operating Manual
(I) Preparations Before Installation:
-
Prepare installation tools and lifting equipment.
-
Check if any part of the pump unit has loosened or been damaged during transportation.
-
Ensure the foundation is level.
(II) Installation Sequence:
-
Upon arrival at the site, if the unit includes a base, the pump and motor will have already been aligned at the factory. Therefore, there is no need for re-alignment during leveling, making the installation process highly efficient.
-
Place the base on the foundation, position wedge-shaped steel plates near the anchor bolts, and raise the base by 20–40 mm for subsequent leveling and cement grouting.
-
Use a level gauge to check the flatness of the base. After leveling, fill the base with cement grout. Once the cement has dried, check the level again.
-
For units with higher power ratings, the pump, motor, and base may be packaged separately for ease of transportation. In this case, follow these steps for installation and alignment:
a. Clean the supporting surface of the base and the mounting surfaces of the pump and motor, then place the pump and motor onto the base.
b. Adjust the pump shaft to a level position, and securely fix the pump to the base with bolts to prevent movement.
c. Lift the motor, align the motor coupling with the pump coupling, and lower the motor into its correct position on the base.
d. Adjust the coupling gap to approximately 5 mm and check if the motor shaft and pump shaft are properly aligned. Use a straightedge to verify that both coupling outer circles are flush. If not, adjust the position of the motor or pump or use shims to correct the alignment.
e. To verify installation accuracy, use a feeler gauge to measure the gap between the coupling faces at several points around the circumference. The difference between the maximum and minimum values should not exceed 0.3 mm, and the difference between the centerlines (up/down/left/right) should not exceed 0.1 mm. -
If the unit does not include a base, it must be installed directly on the foundation. The method is similar to step 4, but extra attention is required for alignment.
(III) Installation Precautions:
-
The pipeline must not exert any force on the pump during installation, as this may cause damage to the pump.
-
Anchor bolts must be tightened during installation. Periodically check to ensure they do not loosen, which could cause severe vibration during pump operation.
-
Before installation, check the pump passage for any hard objects (e.g., stones, iron sand) to prevent damage to the flow parts during operation.
-
To facilitate maintenance and ensure safe operation, install regulating valves and pressure gauges on both the inlet and outlet pipelines.
-
For high-head pumps, install a check valve before the outlet gate valve to prevent water hammer during sudden power failure and ensure long-term stable operation.
-
When operating under suction conditions, a foot valve must be installed. The inlet pipeline should not have excessive bends and must be free from leaks to maintain suction efficiency.
-
To prevent debris from entering the pump and blocking the flow passage, install a filter before the pump inlet.
-
Before connecting the pipeline, manually rotate the pump rotor to ensure it moves freely with no friction or jamming.
-
The pump flanges are designed according to 2.5 MPa standards, so select matching pipeline flanges accordingly.
Startup, Shutdown & Operation
1. Preparations Before Startup:
-
Manually rotate the pump rotor—ensure it rotates freely without friction.
-
Open the inlet valve, close the outlet valve, remove air from the pump, and fill it with liquid.
-
Jog the motor to confirm the rotation direction. If incorrect, swap any two motor wires.
2. Startup & Operation:
-
Fully open the inlet valve and close the outlet valve.
-
Start the motor. After the pump reaches full speed, gradually open the outlet valve and adjust it to the required operating condition.
-
Check instrument readings.
-
Bearing temperature should not exceed 75°C, and should not be more than 35°C above ambient temperature.
3. Shutdown Procedure:
-
Gradually close the outlet valve and disconnect the power supply.
-
Close the inlet valve.
-
If the ambient temperature is below 0°C, drain all liquid to prevent the pump casing from freezing and cracking.
-
For long-term shutdown, disassemble, clean, and properly store the pump.
Maintenance & Care
-
The inlet pipeline must be completely sealed—no air or water leakage is allowed.
-
Long-term cavitation operation is strictly prohibited.
-
Do not operate the pump for extended periods with excessive flow, as this could overload the motor.
-
Regularly check the motor current to ensure operation within the rated working conditions.
-
The pump must be monitored by dedicated personnel to prevent accidents.
-
Lubricate bearings every 500 hours of operation.
-
After long-term use, mechanical wear may cause increased noise and vibration. Stop the pump for inspection and replace worn parts and bearings if necessary. A typical overhaul period is one year.
-
If a fault occurs during operation, troubleshoot according to the provided fault table. If the issue cannot be resolved, do not disassemble the pump yourself—contact our service department or authorized repair center.
