Split case double suction fire pumps are heavy-duty fire pumps used to provide a reliable water supply in fire extinguishing systems that require high flow rates and high pressures. The split design of the casing containing the pump's impeller and hydraulic components makes maintenance, inspection, and service operations easier to perform.

Thanks to the double suction design, water enters the impeller from two different sides, creating a balanced hydraulic structure within the pump. This design contributes to efficient and reliable operation, especially in applications requiring high flow rates. The double bearing structure offers durability against vibrations that may occur under heavy working conditions.

The pump casing is designed to be suitable for operating under high pressure, and the flow range of 68 – 1,700 m³/h provides a solution for applications requiring a large amount of fire extinguishing water. Therefore, it can be preferred in large-scale industrial facilities, commercial buildings, high-rise buildings, and comprehensive sprinkler systems.

In double suction fire pumps, the hydraulic conditions in the suction line are important for safe and balanced operation. Since an unbalanced water inlet can lead to hydraulic imbalance, the fire pump suction installation must be designed in accordance with the design and installation rules specified within the scope of NFPA 20.

Split case fire pumps are connected to the motor via a coupling or a suitable drive connection. Although it may require more space in horizontal mounting compared to some pump types, the split case structure provides significant convenience in maintenance and service operations.
