Model Designation
Key Features
-
Compact Vertical Design: This design is highly suitable for installation in pump rooms or spaces with limited area.
-
Efficient Operation: The impeller is directly mounted on the motor shaft, ensuring excellent concentricity, higher stability, and extended service life.
-
High Durability Sealing System: The system uses mechanical seals or combined sealing systems with high-quality alloy seals, offering excellent wear resistance.
-
Easy Installation and Maintenance: The same diameter for the inlet and discharge ports simplifies pipe connections, making installation and maintenance more convenient.
Engineering Summary
LG Pump Unit adopts a modular design, with rigid integration of the pressure tank and pump components. The optimized hydraulic model design ensures that the pump system operates efficiently and stably. The unit comes with standard configurations for easy installation and maintenance, while maintaining stability under high flow conditions.
