Related centrifugal Pump FAQS

1. Basic Definitions & Concepts

1.1 What is a horizontal centrifugal pump?

A horizontal centrifugal pump is a fluid transfer device with a horizontally mounted impeller shaft, which relies on centrifugal force generated by high-speed impeller rotation to accelerate fluids and realize medium transportation. It is widely used in industrial and municipal scenarios due to its stable operation, easy maintenance and large flow capacity. Horizontal centrifugal pump typically consists of pump body, impeller, shaft, bearing, seal and motor components, and its performance verification complies with international standards such as ISO 9906.

1.2 What is the working principle of a single helix pump impeller?

When the single helix pump impeller rotates, fluids enter the impeller through the suction port and move along the spiral flow channel under the push of blades. The single helix structure reduces fluid turbulence, improves flow stability, and effectively prevents clogging by solid particles and fibrous materials. Compared with traditional impellers, it has better adaptability to complex media and higher energy conversion efficiency in large flow working conditions.
