2 Bearing bracket 8 Impeller
3 Rolling element bearing 9 Foot opening
4 Shaft 10 Suction strainer
Design The pump is designed with a fluid inlet axial to the centreline of the pump set and a
fluid outlet parallel to the centreline, leading upwards. For size 354 the fluid outlet is
horizontal to the centreline, arranged at the impeller level.
The hydraulic system is closed off by the casing wall on the discharge side of the
impeller and runs in rolling element bearings (3, 5). The rolling element bearings (3,
5) are supported by bearing brackets (2) arranged at the pump casing and casing
cover.
The shaft (4) enters through the casing wall and casing cover; it links the hydraulic
system with the drive.
It is sealed to atmosphere by a shaft seal (6) consisting of two shaft seal rings in
tandem arrangement with a grease reservoir fitted in between. The shaft seal is
grease-packed for life and maintenance-free.
Function The fluid handled enters the pump via the suction strainer (10)/ foot opening (9).
The rotating impeller (8) accelerates the fluid handled outward. In the flow passage
of the pump casing the kinetic energy of the fluid handled is converted into pressure
energy. The fluid handled is pumped to the discharge nozzle (1), where it leaves the
pump.

▷Make sure the electrical installation meets the VDE100 installation rules
(sockets with earthing terminals).
▷Make sure the electric mains is equipped with a residual current device of
max.30mA.
▷Always have the electrical connections installed by a trained electrician.
▷Only use the plug and power cable supplied.
DANGER
Use in an outdoor area
Danger of death from electric shock!
▷Any extension cables must match the quality of the supplied power cable.
▷Never expose electrical connections to any moisture.
DANGER
Continuous pump operation in swimming pools, garden ponds or similar
Danger of death from electric shock!
▷Make sure that nobody is in the water while the pump is in operation.
▷Only use the pump for draining swimming pools, garden ponds, etc. (It is
impermissible to use this pump as a recirculation pump, for example.)
5.2 Checks to be carried out prior to installation
Before beginning with the installation check the following:
▪All structural work required has been checked and prepared in accordance with
the dimensions in the outline drawing.
▪The data on the name plate has been checked to make sure the pump set is
suitable for operation on the available power supply network.
(ðSection4.4,Page13)
▪The fluid to be handled matches the description of permissible fluids.

5.3 Preparations for low water level intake (optional for sizes 301, 303)
NOTE
Low water level intake can only be used when the pump is in manual mode or
controlled by an external control unit.
NOTE
When the residual water level of 2mm is reached there is a risk of dry running. If
dry running occurs, switch off the pump set.
NOTE
The suction strainer is fastened to the pump set with clamps. In addition, bolts/
screws (size 4 × 12mm) can be used.
In preparation for low water level intake carry out the following steps:

5.4 Preparations for cleaning the pump sump (optional for size 322)
NOTE
AmaDrainer 322 pumps are delivered with the cleaning openings in the pump foot
closed. If the pump set is to be used for cleaning the pump sump, the cleaning
openings have to be opened by the customer.
NOTE
The pump sump is cleaned by an intended leakage flow from the hydraulic system.
The operating data of the pump set will only be slightly influenced by this process.
