Model Designation
Key Features
-
Integrated motor-pump structure: Compact and vertical, occupying minimal space with stable operation; no alignment required during installation.
-
Coaxial inlet and outlet with identical flange sizes: Can be directly installed inline like a valve, simplifying pipeline layouts.
-
Short shaft design: Ensures smoother operation and lower noise levels.
-
Elimination of traditional shaft seals: Reduces leakage risks, providing a more reliable structural solution.
-
Sliding bearings instead of traditional rolling motor bearings: Achieves ultra-low vibration and noise.
-
Easy maintenance: Rotor assembly can be removed for maintenance without disassembling the pipeline system.
-
Parallel or series operation supported: Accommodates varying flow and head requirements.
Engineering Overview
This series features an integrated single-stage, single-suction centrifugal pump with a canned motor structure. The stator and rotor are isolated by an independent can, while the pumped medium itself serves as both bearing lubricant and cooling fluid. The elimination of traditional shaft seals reduces the risk of moderate leakage and offers structural solutions for leakage-sensitive applications. The pump’s inlet and outlet are coaxial, with the same flange dimensions, enabling direct inline installation, similar to a valve.
Typical Applications
-
Standard type: Suitable for clean water or liquids with similar physical and chemical properties, with medium temperatures ≤ 80°C. Used for industrial and municipal water supply and drainage, high-rise pressure boosting, landscape irrigation, firefighting systems, long-distance water transfer, HVAC cooling/heating circulation, bathing water circulation, and auxiliary equipment systems. Particularly suitable for underground pump stations and HVAC systems that require low noise and vibration.
-
Hot water type: Designed for soft water without solid particles, with medium temperatures ≤ 160°C. Applied in energy, metallurgy, chemical, textile, paper, hotel industries, hot water boiler reinforcement, and district heating systems.
-
Corrosion-resistant type: Used for corrosion-resistant liquids with a viscosity similar to water and no solid particles. Widely used in petroleum, chemical processing, metallurgy, power generation, paper making, food processing, pharmaceutical, and synthetic fiber industries.
System Configuration
This device primarily includes the pump casing, impeller, connector, sliding bearings, stator, rotor, can sleeve, motor casing, and related components. The stator and rotor are separated by an independent can. Bearings are made from graphite-impregnated resin composite materials. The suction medium also acts as a lubricant and cooling fluid. The pump adopts a vertical single-stage single-suction centrifugal design, with the inlet and outlet on the same horizontal axis, and the same flange size, allowing for direct installation in any pipeline location.
Components & Supply
-
Hydraulic parts: Suction part, middle part, guide blades, and discharge part.
-
Rotating assembly: Medium carbon steel shaft, cast iron impeller, balance plate, and shaft sleeve.
-
Bearing assembly: Lubricated rolling bearings to ensure smooth, low-noise operation.
-
Sealing system: Soft packing seals, rubber water seal rings, and O-rings for leakage control and explosion-proof applications.
Technical Service
Installation and maintenance are simplified, requiring no disassembly of the pipeline system. By loosening the connector nuts, the entire rotor assembly can be extracted for inspection or repair. The device is equipped with a base designed for direct foundation mounting. Due to its low noise and vibration characteristics, vibration isolators or pads are typically unnecessary.
Operating Conditions
-
Applicable fluids: Clean water, seawater, mild acidic or alkaline liquids, and general slurry (viscosity ≤100 cP, solid content ≤30%).
-
Cooling requirements: If the pump casing temperature exceeds 70°C, cooling liquid must be introduced through a cooling port to lower the temperature.
-
Maximum system operating pressure: ≤1.2 MPa.
-
Ambient temperature: ≤40°C.
-
Relative humidity: ≤95%.
Service Conditions
-
Applicable fluids: Clean water or liquids with similar properties to water.
-
Solid content: Maximum particle size ≤2mm, volume content ≤1%.
Protective Features
-
Self-priming capability: Provides more reliable self-priming through optimized gas-liquid separation technology.
-
Temperature monitoring: Optional external cooling water system to keep bearing temperature within a safe range.
Selection Criteria
-
Ensure proper selection of seal types and cooling solutions to ensure long-term stable operation of the pump.

Operating Manual
Usage Notes
1. Preparation Before Installation:
-
Check that all fasteners are tight and verify that there are no foreign objects blocking the pump casing or flow passages to avoid impeller or pump body damage during operation.
2. Pipe and Support Installation:
-
The weight of the pipes should not be supported by the pump. Each pipe section must have its own support to prevent pump deformation, which could impact performance and service life.
3. Filter Installation:
-
To prevent impurities from entering the pump and clogging the flow passage, install a filter with an area 3–4 times larger than the suction pipe’s cross-sectional area before the pump inlet.
4. Hot Water Liquid Handling:
-
When handling hot water liquids, to avoid thermal deformation stress from the pipeline, the pump base bolts can remain unfixed. This allows the pump to move with the pipeline during thermal expansion and contraction.
5. Safety and Maintenance:
-
For safety, install regulating valves and pressure gauges at both the inlet and outlet pipelines. This ensures the pump operates within the rated performance range, contributing to the pump’s normal operation and service life.
Maintenance & Care
Pre-Start Preparation and Inspection:
-
Verify the motor’s grounding and electrical connections to ensure proper operation.
-
For newly installed or long-idle motors, check the insulation resistance of the stator windings to the ground, ensuring it is no less than 2MΩ.
-
The pipeline must be fully filled with liquid, as operating without liquid will negatively affect the motor’s service life.
Equipment & Maintenance
-
Regularly record the power supply voltage and its imbalance. Excessive or insufficient voltage, or phase imbalance, can cause overheating or abnormal behavior in the motor.
-
Regularly record the pump’s load current and its imbalance. Most faults manifest as an abrupt increase in stator current, which causes the motor to overheat.
-
Record the liquid temperature regularly to ensure it stays within the limits specified on the nameplate, preventing overheating during prolonged use.
-
Check the pressure gauge readings on both the pump’s inlet and outlet. The inlet pressure should not be lower than zero, and the difference between the inlet and outlet pressures must align with the values specified on the nameplate.
-
Before each operation, exhaust air from the pump. During prolonged operation, this should be done weekly to avoid air accumulation inside the pump, caused by water molecules being stirred and impacted inside the pump.
-
Monitor for unusual odors, vibrations, or noise. Overheated motor windings may emit a burnt insulation smell, and mechanical failures typically show up as vibrations or noise. Immediate shutdown and inspection are required if abnormalities occur.
-
Regularly check the circulating liquid path and filtration system for blockages.
Preparatory Work
Starting and Operation:
-
Fill the pump with liquid and purge the air. Open the inlet valve and the vent valve on top of the motor. Once full, close the vent valve.
-
Close the outlet valve to reduce the starting current.
-
Check all components to ensure normal operation.
-
Power on and ensure the motor rotates in the correct direction.
-
Gradually adjust the outlet valve to maintain operation within the rated performance range.
-
If abnormalities occur during operation, immediately stop the pump and check for issues.
-
Check motor current and temperature rise to ensure they meet the required standards.
Stopping:
-
Close the discharge valve.
-
Cut off the power supply and stop the motor.
-
Close the inlet valve.
-
If the pump is to be out of service for an extended period, drain the pump chamber and clean the unit to avoid freezing and damage.
Precautions：
Regularly check and measure the gap between the graphite bearing and the shaft sleeve to ensure uniform clearance between the stator and rotor shielding sleeves, ensuring reliable operation of the equipment. Under normal circumstances, the standards in the following table are the limits; if they exceed the specified values, repairs or replacements should be made.
