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-efficiency fluid-handling device designed for medium-to-large flow transfer, featuring a Double Spiral Pump Impeller to minimize clogging. It integrates key centrifugal pump components such as pump body and mechanical seal, complying with ISO 13709 (hydraulic performance) and IEC 60529 (IP rating) global standards. KOLEBURG LV150SL is a typical representative optimized for wide flow-head adaptation.

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

The Double Spiral Pump Impeller uses dual spiral channels to guide solids and fibrous media smoothly through the volute. When the motor drives the impeller to rotate at 490-1450 rpm (4/6/8/12-pole adjustable), it generates stable centrifugal force to suck in fluid and lift it to 5.5-50 m head, achieving 65-274 m³/h flow. This design reduces clogging failures by over 80% compared to standard impellers (third-party tested), aligning with EN 733 flow rate standards.

2. Functions and Applications

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

Medium-to-large flow centrifugal pumps like KOLEBURG LV150SL mainly realize three core functions: stable transfer of 65-274 m³/h fluid, flexible adaptation to 5.5-50 m head requirements, and reliable operation in solid-laden media. They combine anti-clog performance with energy efficiency, meeting fluid management needs of industrial, agricultural, and municipal medium-to-large projects.

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

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