Multi-Stage Vertical Inline Pumps (MVIL) are a type of centrifugal pump that is used to transport liquids. These pumps are designed to have several impellers or stages, each of which contributes to the overall pressure head or lift of the pump.
The MVIL pump consists of a vertical, in-line design that allows it to be installed directly in the piping system. The motor is typically located at the top of the pump, and the impellers are arranged in a series, one above the other, inside a common casing. The impellers are connected by a common shaft and are usually enclosed in a diffuser.
