The company holds ISO9001, ISO14014, ISO45001 management system certifications, Five-star After-sales Service Certification and AAA credit rating. In the field of flood control drainage, we focus on three electric pump series: Permanent Magnet High Flow Pump, Electric Driven High Head Pump, and Oil-Filled Submersible Pump. Each series is specifically designed for different scenarios, collectively covering the full range of flood control and emergency drainage applications.
Product Comparison and Selection Guide
Core: permanent magnet synchronous motor + lightweight design
Applications: Rapid drainage of large-scale urban waterlogging, emergency flood discharge from rivers and lakes, high-volume pumping for construction pits and underground garages, rapid water diversion at flood control sites.
Advantages: 30% lighter, 15-20% higher efficiency, flow 200–1500 m³/h, deploy within 3 minutes.
Selection advice: Choose for high-volume, fast drainage with lightweight & energy saving requirements.
Core: multi-stage impeller + high-head hydraulic model
Applications: Deep drainage for foundation pits/wells, long-distance pumping from low areas, pipeline pressurization, reservoir/station water supply.
Advantages: Head 80–200 meters, stable continuous operation, VFD compatible, wear-resistant seals.
Selection advice: Ideal for large height differences (e.g., basements 3+ levels) or long-distance delivery.
Core: oil-filled chamber cooling + fully submersible design
Applications: Dewatering flooded basements/electrical rooms, tunnel/culvert drainage, routine river/lake maintenance, mobile emergency drainage.
Advantages: Excellent heat dissipation, superior sealing, handles 5% sand content, effective motor cooling.
Selection advice: Choose for long-term full submersion and muddy/sediment-laden water (flood conditions).
