1. High-Efficiency and Energy-Saving Design
IE3/IE4 High-Efficiency Motors: Standard motors compliant with international energy efficiency standards (power range: 0.12–315 kW), significantly reducing energy consumption.
Optimized Hydraulic Performance: Flow rates up to 920 m³/h, heads up to 100 m, and a liquid temperature range of -25°C to +140°C.
2. Flexible Adaptation and Reliable Materials
Versatile Flange Connections: Supports DN32–DN350 flanges with a PN16 pressure rating to meet diverse piping system requirements.
Material Options: Pump casings available in cast iron (EN-GJL-250) or stainless steel (1.4308/1.4408); impellers available in cast iron, bronze, or stainless steel to suit various liquid media.
3. Durability and Ease of Maintenance
Mechanical Shaft Seal: Standard BQQE-type silicon carbide/silicon carbide seal (EPDM); EPDM/FKM seal options available for special media such as glycol mixtures.
Top-Pull-Out Design: Allows for the removal of the motor and impeller assembly without disconnecting piping, minimizing downtime.
Wear Ring Design: Replaceable wear rings ensure sustained high-efficiency operation.
4. Wide Range of Applications
Typical Applications: District heating, HVAC systems, industrial circulation, water supply systems, and coolant transport.
Liquid Compatibility: Suitable for clean, non-corrosive liquids; supports the addition of antifreeze (requires selection of appropriate shaft seal).
5. Smart and Quiet Operation
Low-Noise Operation: Sound pressure level ≤70 dB(A), compliant with EN ISO 4871 standards.
VFD Compatibility: Supports variable frequency drive control to meet dynamic flow demands (consideration of motor insulation and cooling requirements is necessary).
6. Structural Advantages
In-Line Installation: Saves space and reduces piping stress.
Hydraulically Balanced Impeller: Reduces axial thrust, extending the service life of bearings and shaft seals.
7. Environmental Adaptability
Wide-temperature operation: Suitable for ambient temperatures ranging from -20°C to +55°C (standard motor); special versions can extend this range to -30°C.
Surface treatment: Electrophoretic coating (epoxy resin) enhances corrosion resistance, making it suitable for high-humidity environments.
