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.

Related Submersible Pump FAQS

1. Basic Definitions and Core Concepts

1.1 What is a single helix impeller centrifugal pump?

A single helix impeller centrifugal pump is a high-flow fluid transfer device designed to handle media containing solids and fibrous materials. It features a Single Helix Pump Impeller that minimizes flow resistance and clogging risks. The core structure includes a pump body, impeller, shaft, and mechanical seal, operating on the principle of converting motor rotational energy into fluid kinetic energy via centrifugal force. KOLEBURG LV300L, a typical model of this type, complies with ISO 13709 (hydraulic performance) and IEC 60529 (protection rating) international standards, ensuring reliable operation in large-scale fluid management scenarios.

1.2 How does a single helix impeller work in centrifugal pumps?

The Single Helix Pump Impeller rotates at 740-970 rpm (driven by 6/8-pole motors) to generate centrifugal force, drawing fluid into the pump cavity through the suction port. The spiral-shaped channel of the impeller guides fluid and solid particles smoothly toward the discharge port, converting rotational energy into static pressure to achieve head (8.6-21 m) and flow rate (680-700 m³/h) requirements. This design reduces flow turbulence by 35% compared to traditional impellers (third-party test data), aligning with EN 733 flow stability standards.

2. Functions and Applications

2.1 What are the core functions of large-flow centrifugal pumps?

Large-flow centrifugal pumps like KOLEBURG LV300L primarily fulfill three core functions: efficient transfer of 680-700 m³/h fluid, stable adaptation to 8.6-21 m variable head conditions, and reliable handling of solid-laden media (solid content ≤15%). They integrate anti-clog, corrosion-resistant, and energy-saving features, meeting the fluid transfer needs of municipal, industrial, and agricultural large-scale projects.

2.2 What application scenarios are suitable for single helix centrifugal pumps?

The single helix impeller design makes KOLEBURG LV300L ideal for scenarios requiring large-flow and anti-clog performance. All recommended scenarios comply with local environmental protection and industrial operation standards:
Scenario
Handled Media
Core Advantage
Sewage Treatment Plant
Activated sludge, secondary sewage
Anti-clog & large-flow transfer
Sewage Recycling System
Reclaimed water
Stable flow & corrosion resistance
Food Processing Industry
Organic wastewater
Hygienic material compatibility
