Structural Features
MC Series Medium Consistency Pumps feature innovative design to ensure efficient and reliable performance
Spiral-Centrifugal Composite Impeller
The core uses a single-blade three-dimensional spiral impeller. The inlet section forms a spiral positive displacement pump structure to achieve forced suction of high-concentration media; the outlet section converts to a centrifugal impeller to increase head. This design solves the clogging problems of traditional centrifugal pumps and can handle pulp concentrations up to 12% or sewage with solid content up to 14%.
Modular Sealing and Bearing System
Shaft seals support packing seals (standard type ≤80°C) and double mechanical seals (high temperature type ≤120°C), with optional dynamic seals (no external water required). Heavy-duty bearing housing with oil lubrication or grease lubrication adapts to high temperature and high pressure conditions (such as 180°C, 25bar).
Degassing and Wear Resistance Enhancement
Efficiently separates gas from the slurry, avoiding cavitation and improving operational stability. Flow components (impeller, liner) can be coated with wear-resistant coatings or hardened to extend service life.
Non-Clogging Flow Channel Design
Extra-large flow channel design allows passage of solid particles with diameters of 40–150mm (such as bagasse, slaughter waste), ensuring smooth operation and reducing clogging and maintenance requirements.
