Our advantages
Double Spiral Pump Impeller
The double spiral pump impeller is engineered with two symmetrically arranged spiral flow channels, which work in tandem to enhance hydraulic efficiency and solids handling performance. This innovative design ensures smooth fluid transition and balanced load distribution, reducing turbulence and vibration during operation.
By incorporating a dual-passage structure, the impeller effectively handles large solid particles, fibrous materials, and sludge with minimal risk of clogging. The spiral geometry promotes a natural guiding motion, allowing debris to pass through smoothly without accumulating at the inlet or within the flow channels.
This impeller is particularly suitable for demanding applications such as industrial wastewater, municipal sewage, and drainage systems containing high concentrations of suspended solids. Its robust anti-clog design supports long-term, stable operation while maintaining high pumping efficiency and durability under continuous heavy-duty conditions.

1. Basic Definitions and Core Concepts
1.1 What is a double spiral impeller centrifugal pump?
A double spiral impeller centrifugal pump is a high-flow fluid transfer device engineered with a Double Spiral Pump Impeller to minimize flow resistance and clogging. Its core components include a pump body, impeller, shaft, mechanical seal, and belt-driven system, operating on the principle of converting motor rotational energy into fluid kinetic energy via centrifugal force. KOLEBURG LV400SL, a representative model of this type, complies with international standards such as ISO 13709 (hydraulic performance) and IEC 60529 (protection rating), ensuring reliable operation in large-scale fluid management scenarios.
1.2 How does a double spiral impeller work in centrifugal pumps?
The double spiral impeller of KOLEBURG LV400SL rotates at 740 rpm (driven by an 8-pole motor) to generate centrifugal force, drawing fluid into the pump cavity through the suction port. The dual spiral channels guide fluid and solid particles smoothly toward the 400 mm discharge port, converting rotational energy into static pressure to achieve 5-10 m head and 1500 m³/h flow rate. This design reduces flow turbulence by 60% compared to traditional impellers (third-party test data), aligning with EN 733 flow stability standards.

KOLEBURG LV400SL adapts to various media types, with recommended conditions as follows. For special media, customized material configurations are available:
Media Parameter | Suitable Range | Special Suggestion |
|---|---|---|
pH Value | 4-10 | ＞10/＜4: Use 316L Stainless Steel or Duplex 2205 |
Solid Content | ≤18% | ＞18%: Use Rubber-Lined Pump Body + High-Chromium Impeller |
Temperature | ≤80°C | ＞80°C: Custom High-Temperature Seals & Insulation |
Viscosity | ≤50 mPa·s | ＞50 mPa·s: Custom Impeller Design |
Suitable media include activated sludge, organic wastewater, food waste, and high-viscosity sludge, complying with ASTM A240 (stainless steel) and other material standards. It is not suitable for high-temperature, high-viscosity, or highly corrosive media (e.g., concentrated acid/alkali) without customization.
10.1 What does IP68 waterproof rating mean for centrifugal pumps?
IP68 (IEC 60529) is the highest waterproof rating for electrical equipment, indicating KOLEBURG LV400SL can operate continuously under water (depth ≤1.5m for 24 hours) without electrical hazards. This feature is critical for wet environments like sewage treatment plants, complying with IEC 61558 (electrical equipment safety) standards to ensure operational safety for operators and equipment.
