4 Description of the Pump (Set)
16 of 60 Amarex N S 32-160
Design The pump is designed with an axial fluid inlet and a radial outlet. The hydraulic
system sits on the extended motor shaft. The shaft runs in common bearings.
Function The fluid enters the pump axially via the suction nozzle (5) and is accelerated
outward in a cylindrical flow by the rotating impeller (6). 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 (3), where it leaves the pump. At the rear
side of the impeller, the shaft (1) enters the hydraulic system via a discharge cover.
The shaft passage through the cover is sealed towards the atmosphere with a shaft
seal (7). The shaft runs in rolling element bearings (8 and 9), which are supported by
a bearing bracket (2) connected to the pump casing and/or discharge cover.
Sealing The pump is sealed by a bi-directional mechanical seal at the pump end and a shaft
seal ring at the motor end.
A lubricant reservoir between the shaft seal ring and the mechanical seal provides
cooling and lubrication.
