centrifugal slurry pump

centrifugal slurry pump for metallurgy and coal mining

Centrifugal slurry pump is a single-stage axial suction centrifugal pump, which is widely used in the industry of conveying solid particles (such as ore, coal ash, mud, etc.) and liquid mixtures (i.e. slurry).

Description

The centrifugal slurry pump incorporates advanced Olbermann pump design concepts and two-phase flow theory. With wear-resistant main over-flow parts, it effectively resists the abrasion caused by solid particles in slurry, ensuring enhanced durability and a prolonged service life.

centrifugal slurry pump Working principle:

The pump uses high-speed impeller rotation to move a mixture of liquid and solid particles into the pump body. Centrifugal force pushes the slurry through the pump, and as the channel expands, fluid speed is transformed into pressure, resulting in smooth discharge from the outlet. Solid particles are pumped together with the liquid, making it ideal for concentrated and abrasive media.

centrifugal slurry pump Features:

  • Strong abrasion resistance: Overflow parts made from wear-resistant materials (high chrome alloy, rubber lining, etc.) prolong service life.
  • Wide range of applications: Efficiently handles solid-liquid flows with suspended particles—slurry, coal slurry, mud, corrosive liquids, etc.
  • Reasonable structure: Optimized bearing and seal design minimizes failures; corrosion-resistant pump body suits harsh environments.
  • High efficiency: Two-phase flow theory and hydrodynamic optimization ensure high efficiency and low energy consumption.
  • Multi-specification options: Various specifications meet different flow, head, and pressure needs.
