The hydraulic main pump is a kind of fluid pump. About the fluid sealing, it usually uses the mechanical seal to contain the fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

Mechanical seals are usually fixed at the point of entry or exit of a rotating shaft. Typically it is used to prevent the leakage of one high-pressure fluid into a lower pressure fluid.

And to maintain the power of the hydraulic main pump.
