CB Horizontal Split Case Pump
The EBARA CB Horizontal Split Case Pump is a single-stage, double-suction centrifugal pump engineered for reliable, high-capacity water transfer and circulation. Designed for efficiency and simplicity, the CB delivers robust hydraulic performance with a compact footprint and easy maintenance features.
With a flow capacity up to 16,375 gpm and heads reaching 492 ft, the CB series delivers consistent, energy-efficient operation across municipal, industrial, and building service applications — from water distribution and process cooling to HVAC and irrigation systems.
PRINCIPLE OF OPERATION
The CB is a single-stage, double-suction centrifugal pump with a horizontally split casing, allowing easy access to internal components for inspection and maintenance without disturbing the piping or motor alignment.
The double-suction impeller design balances axial thrust, improving bearing life and minimizing vibration. Water enters the impeller from both sides, ensuring smooth hydraulic performance and efficient energy transfer.
This configuration makes the CB ideal for continuous-duty applications that require high flow, stable pressure, and reliable operation under varying system demands.
These pumps are only available in Canada.
Features & Benefits
Delivers optimized hydraulic performance, reducing energy consumption and operational costs.
The horizontal split configuration minimizes footprint requirements while maximizing flow capacity.
Horizontally split casing and accessible components allow fast inspection and servicing without dismantling piping.
Cast-iron casing and stainless-steel impeller provide corrosion resistance and long service life in demanding environments.
Shielded bearings ensure smoother operation and longer bearing life.
Supports flow rates up to 16,375 gpm (3719 m³/hr) and heads up to 492 ft (150 m) — ideal for large-scale water movement systems.
Double-suction impeller balances hydraulic forces, minimizing shaft deflection and vibration.
Industries & Applications
The CB Split Case Pump is designed for high-capacity water movement in public utilities, industrial processes, and commercial building systems.
