The CPS series split case double suction pump is engineered for high efficiency, reliability, and long service life in demanding industrial and commercial applications. Designed as a single-stage, double suction impeller pump, it offers excellent hydraulic balance and reduced axial thrust, ensuring smooth and stable operation even under heavy-duty conditions.
Key Design Features
Double Suction Impeller: Provides balanced axial forces, minimizing vibration and extending bearing life.
Between Bearings Support: The impeller is supported on both sides, reducing shaft deflection and improving operational stability.
Horizontal or Vertical Installation: Flexible mounting options make it suitable for different system layouts and space conditions.
Casing Design: The suction and discharge nozzles are integrally cast in the lower half of the casing, positioned on the same horizontal centerline for easy piping and simplified installation.
Material Options: Available in a wide range of materials including cast iron, ductile iron, stainless steel, and bronze, making it suitable for clean water, seawater, cooling water, and various industrial fluids.
