outward in a cylindrical flow by the rotating impeller (7). In the flow passage of the
pump casing the kinetic energy of the fluid is converted into pressure energy. The
fluid is pumped to the discharge nozzle (4), where it leaves the pump. At the rear
side of the impeller, the shaft (1) enters the hydraulic system via the discharge cover
(3). The shaft passage through the cover is sealed to atmosphere with a shaft seal (8).
The shaft runs in rolling element bearings (9 and 10), which are supported by a
bearing bracket (2) joined to the pump casing and/or discharge cover.
A lubricant reservoir in-between the seals ensures cooling and lubrication of the
mechanical seals.
