A mechanical seal is a device that helps prevent fluid leaks between two surfaces that move relative to each other. In the context of fire pumps, mechanical seals are used to create a barrier between the pump casing and the shaft or rotor, thereby preventing water or other fluids from leaking out of the pump. This is particularly important in fire pumps, as even minor leaks can compromise the system’s effectiveness in emergencies.

There are several types of mechanical seals available for oil pumps, each suited for different applications
