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 Centrifugal Pump FAQS

1. Basic Definitions and Core Concepts

What is a horizontal centrifugal pump?

A horizontal centrifugal pump is a mechanical device for fluid transfer with a horizontally mounted shaft aligned with the motor. It converts rotational energy from the motor into fluid velocity and pressure via the impeller, enabling continuous and efficient transportation. This type is widely used in industrial and municipal scenarios due to its stable operation, easy maintenance, and large flow capacity advantages, which align with global industrial design norms.

How does a horizontal centrifugal pump with single/double spiral impeller work?

When the motor drives the Single Helix Pump Impeller or Double Spiral Pump Impeller to rotate, fluid entering the impeller channel is subjected to centrifugal force and thrown outward to the pump casing. The volute-shaped pump casing reduces fluid velocity and converts kinetic energy into pressure energy, realizing directional transportation. The spiral structure ensures smooth flow, minimizing clogging risks and enhancing adaptability to complex media.

What are the core components of a horizontal centrifugal pump?

The core components include impeller, pump casing, shaft, mechanical seal, and bearing. The impeller is the power core; the pump casing provides flow channels; the shaft transmits torque; the mechanical seal prevents leakage; the bearing ensures stable rotation. All components of KOLEBURG BH400SL are designed to coordinate with each other, meeting EN ISO 9906 hydraulic performance standards.

2. Functions and Applications

What are the main functions of the KOLEBURG BH400SL horizontal centrifugal pump?

Its core functions include large-flow fluid transfer (1500-2000 m³/h) with low-to-medium lift (5-32 m), handling media containing solid particles and fibrous materials, and energy-efficient operation via IE3 motors. It is engineered to maintain stable performance in harsh industrial environments, supporting continuous production processes.

6. Installation, Use and Maintenance

How to correctly install the horizontal centrifugal pump?

Correct installation is the premise of stable operation. First, select a flat and solid foundation to ensure the coaxiality of the pump and motor (coaxiality error ≤0.05 mm). Second, connect the inlet and outlet pipelines, ensuring tight connection without leakage, and install a filter at the inlet to prevent large particles from entering. Finally, check the mechanical seal tightness and bearing lubrication. The entire installation process complies with API 610 centrifugal pump installation standards.

What are the key points of daily use and maintenance?

Daily maintenance can effectively extend the pump’s service life. The following table summarizes the key maintenance items and cycles:
