Filtra N

Function The fluid enters the pump via a suction nozzle (2) and is accelerated outwards 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 (1), where it leaves the pump. At the rear side of the impeller, the shaft (3)

enters the casing via the casing wall. The shaft passage through the cover is sealed

towards the atmosphere with a shaft seal (4). The shaft runs in a rolling element

bearing.

Sealing The pump is sealed by a mechanical seal with rotating torque-transmitting elements.
