Advantages of the Horizontal Coupling Pump


1. Non clogging spiral centrifugal impeller

Adopting a spiral centrifugal impeller and a sharp angle design at the blade inlet, the debris is guided near the axis and transported along the axial direction by the spiral propulsion effect, truly achieving unobstructed operation and smoothly transporting media containing large particles, long fibers, and high concentrations.


2. Soft conveying, non-destructive medium

Spiral blades allow solid matter to flow through without impacting any part of the pump, making them suitable for transporting fragile substances such as activated sludge, live fish, fruits and vegetables, while maintaining the original physical state of the medium.


3. Energy saving control of variable frequency motor

Using a variable frequency motor drive, continuous adjustment of flow rate and head is achieved by adjusting the speed, avoiding valve throttling losses. According to the similarity law of centrifugal pumps, when the flow rate is reduced by 20%, the power consumption can be reduced by about 50%, and the energy-saving effect is significant.


4. Horizontal coupling structure

The motor and pump shaft are directly connected through a coupling, which has a compact structure, smooth operation, low vibration, and low noise, making it easy for pipeline layout and installation maintenance.



Installation and maintenance


  • The product adopts a horizontal installation method: the pump unit is installed on a concrete foundation and fixed with anchor bolts to ensure a levelness of ≤ 0.2 mm/m.

  • The inlet and outlet pipelines of the pump are connected by concentric reducers. Valves and filters are installed in the inlet pipeline, and pressure gauges, regulating valves, and check valves are installed in the outlet pipeline. Before starting, turn the engine flexibly and confirm that the motor direction is consistent with the pump direction. Use soft start or variable frequency start.

  • Regularly check the bearing temperature, vibration value, mechanical seal, and lubrication condition to ensure long-term stable operation.



Selection Recommendation


When selecting, it is necessary to provide the properties of the medium (density, viscosity, solid content, temperature, corrosiveness, etc.) and system parameters (flow rate, head, pipeline layout, etc.). Qingdao Gongli Technology Co., Ltd. will provide a complete performance curve and selection plan to ensure that the working point falls within the high-efficiency zone and achieve energy-saving and efficient operation.
