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 double spiral impeller centrifugal pump?

A double spiral impeller centrifugal pump is a high-performance fluid transfer device designed for medium-to-large flow and medium-head scenarios. It features a Double Spiral Pump Impeller that enhances flow stability and reduces clogging. Integrating key centrifugal pump components such as pump body and mechanical seal, it complies with ISO 13709 (hydraulic performance) and IEC 60529 (IP rating) global standards. KOLEBURG LV200SL is a typical model optimized for complex media transfer.

1.2 How does a double spiral impeller work in centrifugal pumps?

The Double Spiral Pump Impeller utilizes dual symmetric spiral channels to guide fluid and solid particles smoothly through the volute. When driven by a 6/8-pole motor (720-980 rpm), it generates stable centrifugal force to draw in fluid, achieving a flow rate of 320-450 m³/h and a head of 16-34 m. This design reduces flow turbulence by 40% compared to single spiral impellers (third-party tested), aligning with EN 733 flow rate standards.

2. Functions and Applications

2.1 What are the core functions of medium-head centrifugal pumps?

Medium-head centrifugal pumps like KOLEBURG LV200SL primarily fulfill three core functions: efficient transfer of 320-450 m³/h fluid, stable adaptation to 16-34 m head requirements, and reliable operation in solid-containing and fibrous media. They combine high flow capacity with anti-clog performance, meeting fluid management needs in municipal, industrial and agricultural large-scale projects.

2.2 Which application scenarios are suitable for double spiral impeller centrifugal pumps?

Based on KOLEBURG LV200SL’s performance characteristics, the following high-demand scenarios are optimal, all complying with local environmental regulations and ISO 13709 standards:
