Design The pump is designed with an axial fluid inlet and a radial fluid outlet. The hydraulic
system runs in its own bearings (3, 4) and is connected to the motor by a shaft
coupling (2). Thanks to the graded lengths of support column (13) and shaft (7) the
pump set can be matched to various immersion depths. The pump set is mounted on
a cover plate (6). The discharge nozzle of the volute casing (17) is connected with the
discharge nozzle (12) of the cover plate via a riser (14). If on request the pump set is
supplied without cover plate and riser, it is supplied with a bracket.
Function The fluid enters the pump via the suction nozzle (11) and is accelerated outward by
the rotating impeller (10). 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 (17), where it leaves the pump. The controlled gap seal (16) prevents any fluid

4 Description of the Pump (Set)
18 of 52 Etanorm V
from flowing back from the casing to the suction nozzle. At the rear side of the
impeller, the shaft (7) enters the hydraulic system through the casing cover (9). The
shaft runs in rolling element bearings (3 and 4), which are supported by a bearing
lantern (5) linked with the pump casing and/or casing cover (9) via the support
column (13).
Sealing The pump is seal-less with little leakage flowing into the support column (8) at the
shaft passage (9) and then through the overflow opening (7) back to the tank.

5.1 Safety regulations
DANGER
Installing electric equipment (motors) in potentially explosive atmospheres
Risk of explosion!
▷Comply with the applicable local explosion protection regulations.
▷Verify the test certificate of the motor.
▷Keep the test certificate close to the location of operation (e.g. in the foreman's
office).
5.2 Checks to be carried out prior to installation
Check the structural work.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.
5.3 Installing the pump set
Foundation The sturdy cover plate 68-3.01 serves as a foundation on which the pump set is
fastened. This cover plate covers the tank opening completely. If the pump set is
supplied with cover plate and riser, the cover plate is supported by a sectional steel
frame provided on the tank.
If ordered without cover plate and riser, the pump set is supplied with a bolted-on
bracket 732. This bracket serves to mount the pump set on the tank.
Installing the pump
1. Carefully align the support for the cover plate or the base of the bracket.
2. Align the upper flange of the bearing/intermediate lantern with a spirit level.
3. Make adjustments between cover plate and tank edge, if required.
If the pump is installed without a suction strainer, observe a minimum distance
B to the tank floor.
