Welcome to Credo, We are an Industrial Water Pump Manufacturer.
Split Casing Pump
The split casing pump is a double suction, single-stage centrifugal pump designed for high efficiency, stable operation, and long service life. Its symmetrical impeller and split casing ensure excellent hydraulic balance, low vibration, and strong cavitation resistance, while the horizontally split design allows easy access to internal parts without removing piping. Combining efficiency, reliability, and easy maintenance, it is widely used in industrial, commercial, and municipal applications worldwide.
Key Design Features
Double Suction Impeller: Fluid enters the impeller from both sides, balancing axial thrust, minimizing shaft deflection, and extending bearing life.
Single-Stage Centrifugal Design: Provides high flow capacity with relatively low to medium heads, ideal for large-scale water transfer applications.
Horizontally Split Casing: The casing can be opened along the shaft centerline, giving direct access to the impeller, bearings, and shaft without disturbing pipe connections.
High Hydraulic Efficiency: Optimized flow channels reduce energy losses, ensuring excellent efficiency and reduced operating costs.
Good Cavitation Performance: Low NPSH requirements help prevent cavitation damage, ensuring stable and safe operation even under challenging suction conditions.
