I. Innovative Split-Structure Design

Featuring a modular split-structure design, the pump body and motor are connected via an easily removable spacer coupling, enabling "back pull-out" maintenance; this allows for the rapid replacement of mechanical seals and impeller assemblies without dismantling the motor or piping, significantly reducing downtime and maintenance costs. The design complies with EN 733 interface standards, facilitating seamless replacement and retrofitting within existing systems. Cast components feature an electrophoretic coating, significantly enhancing corrosion resistance and extending equipment service life in harsh environments.

II. High Efficiency, Energy Saving, and Intelligent Operation

Equipped with a wide-frequency, high-efficiency motor suitable for variable-frequency operation, the unit achieves a reduction in electromagnetic noise of over 30% and a 25% increase in motor lifespan. Advanced hydraulic modeling optimizes the clearance between the impeller and pump body (minimized to 0.2 mm); combined with precision impeller diameter trimming, the overall pump efficiency exceeds the GB 19762-2007 energy-saving benchmark by 5.7%–7.9%, reducing energy consumption by over 15% across all operating conditions. Bearings feature reserved interfaces for temperature and vibration monitoring, providing real-time fault warnings to minimize unplanned downtime.

III. Superior Reliability and Quiet Operation

A unique balance hole design effectively eliminates axial thrust, reducing bearing loads by 50%; this, combined with self-lubricating, maintenance-free bearings, ensures vibration levels remain below industry standards. Options include cast iron or bronze impellers (temperature range: -20°C to 120°C) suitable for transporting clean water, slightly contaminated water, and glycol mixtures with near-zero leakage rates. Sealing options include dual-spring mechanical seals and cooling-free gland packing seals to meet specific leakage-prevention requirements for various media.

IV. Diverse Industrial and Construction Applications

• HVAC Sector: Heating system circulation (120°C hot water), chilled/cooling water transport for air conditioning, and core pump units for district energy stations;
• Industrial Applications: Process cooling circulation, chemical medium transport (corrosion-resistant models), and fire sprinkler system pressurization;
• Civil Facilities: Water supply pressurization for high-rise buildings, circulation systems for commercial complexes, geothermal energy utilization, and snow-making systems for ski resorts;
• Specialized Applications: Municipal irrigation, cooling for power plant auxiliary equipment, and offshore platform operations; flow rates ranging from 3.5 to 625 m³/h and a maximum head of 163 m.
