The benefit of detachable body fire pumps is that the impeller-containing section of the pump can be removed and repaired. This type of pump can withstand significant vibration and has two bearings. Typically, their bodies are pressure-resistant. They are robust enough to function in incredibly high water flows.

The water inlet to the impeller in this type of pump is made from two separate locations, hence the name "double suction." A hydraulic imbalance can occur if the water inlet to the pump is uneven, causing damage to the pump shaft. As a result, NFPA-20 has imposed restrictions on the length of the pipe in the suction section of Split Casing Double Suction Fire Pumps.

Split-casing pumps are coupled to the motor through an axle or connection. So, if installed horizontally, they occupy a substantial amount of space. The detachment of the casing makes them easier to maintain than other fire pumps, which extends their lifespan despite being more expensive.
