Description

Engineering & Construction Submersible Dewatering Pump

Application:

  • Construction Site Drainage: Ideal for dewatering excavations, tunnels, and flooded sites containing light sand.

  • Subway & Tunnel Engineering: Reliable drainage for underground infrastructure projects.

  • General Industrial Wastewater: Suitable for industrial facilities where light sediment removal is required.

  • Public Facility Maintenance: Versatile drainage for public and municipal infrastructure.

  • Water Circulation: Effective for moving water containing fine particles.

FEATURES:

  • 5% Sand-Handling Capacity: Precision-engineered to efficiently handle fluids with up to 5% light sand content, making it the ideal choice for construction drainage.

  • Overload & Thermal Protection: Built-in dry-type overload protector effectively prevents motor overheating during continuous operation.

  • Superior Heat Dissipation: Features a water-cooling jacket design and stainless steel casing, significantly increasing heat diffusion efficiency.

  • Wear-Resistant Components: Constructed with a high-chrome alloy steel impeller and agitator (HCR, 2HP and above), providing excellent wear resistance against fine particles and sand.

  • Advanced Sealing System: Fitted with dual SiC/SiC mechanical seals and dual oil seals for superior protection against abrasive sand particles.

  • Stress-Eliminating Design: The pump housing and stress-eliminating plate are designed to reduce flow stress, ensuring long-term reliability in abrasive environments.

  • Advanced Humidity Protection: Cable wires and bases are upgraded with EPOXY resin filling to ensure electrical reliability in high-humidity conditions.
