Horizontal split-case fire pumps commonly use an axially split casing with a double-suction impeller, while the upper casing can be removed to provide access to internal components without disturbing connected piping on applicable designs.

Benefits of Horizontal Split Case Fire Pump

1. Convenient Internal Access: The split casing provides practical access to internal components for inspection and servicing. This is one of the major reasons horizontal split-case designs are widely selected for fire suppression applications.
2. Balanced Hydraulic Operation: A double suction Horizontal Split Case Fire Pump draws water toward both sides of the impeller. This configuration can provide balanced hydraulic loading and is particularly suitable for high-capacity pumping duties.
3. Reliable Long-Term Service: Heavy-duty shafts, bearings, casing construction and properly selected materials can provide dependable service when the pump is correctly installed, operated and maintained.
4. Flexible Driver Selection: Depending on the fire protection design, the pump can be paired with an electric motor or diesel engine. Complete fire-pump product lines are available in both electric- and diesel-driven arrangements.
5. Easier Maintenance Planning: The accessible split-case construction can simplify inspection and component servicing while reducing the need to disturb connected piping during certain maintenance activities.
