Whirl system (Sys-
téme SAN)
The pump can be completely submerged in the fluid.
The submersible pump housing consists of stainless steel.
The electric motor is protected against the pump chamber by
a rotary shaft seal to seal the motor against the oil chamber
and a mechanical seal to seal the oil chamber against the
fluid. The mechanical seal chamber is filled with medical white
oil so that the mechanical seal is lubricated and cooled during
a dry run. A further rotary shaft seal protects the mechanical
seal facing the fluid.
The motor is cooled by the surrounding fluid.
The pump is installed on the floor of a shaft. For a stationary
installation, it is bolted to a fixed pressure pipe or for a transport-
able installation, it is connected to a hose connection.
The pumps are commissioned by plugging in the protective
contact plug.
They operate automatically, when the float switch switches
the pump on from a certain water level "h" (FIG. 2) and
switches it off at a minimum water level ''h1".
The motors are equipped with thermal motor protection, which
switches off the motor automatically if it overheats and
switches it on again when it has cooled down. The condenser
is integrated in the single-phase motor.
Version with whirl system (Systéme SAN)
For waste water with precipitating and floating particles, the
submersible pump has been equipped with a whirl system at
the suction strainer. Precipitating particles are continuously
whirled up in the suction area of the pump and pumped off
with the water. Therefore, mud accumulation in the pump
shaft, with problematic consequences such as clogging of the
pump and odour formation, is largely prevented.
If the removal of the waste water does not allow any interrup-
tion, a second pump (automatic standby pump), together
with the necessary switchgear (accessory), increases the oper-
ating reliability if the 1st pump develops a fault.
7. INSTALLATION AND ELECTRICAL CONNECTION
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connec-
tions can result in a risk of fatal injury.
•The installation and electrical connections should only
be done by properly skilled staff and in compliance
with the applicable regulations!
•Follow all accident prevention regulations!

7.1 Installation
The pump is designed for stationary or transportable installa-
tion.
CAUTION! Danger of property damage!
Danger of damage due to incorrect handling.
Only suspend the pump by the strap with the aid or a
chain or rope, never by the electrical or float switch
cable or the pipe/hose connection.
The installation site or shaft for the pump must be free of frost.
The shaft must be cleared of coarse material such as rubble
before setting up and starting the pump.
The quality of the shaft must guarantee the unhindered mobil-
ity of the float switch.

The diameter of the pressure pipe (pipe/hose connection)
should not be smaller than the pressure connection of the pipe
because of the increased risk of clogging and greater pressure
losses. To avoid pressure losses, it is recommended that the
pipe connection one number higher is selected.
Stationary wet sump installation
In the case of a stationary wet sump installation of the pump
with a permanent pressure pipe, the pump must be positioned
and secured so that:
•The pressure pipe connection does not support the weight of
the pump.
•The load of the pressure pipe does not act on the connecting
socket.
•The pump is installed stress-free.
To protect against any backflow from the public drainage
pipe, the pressure pipe must be taken in an arc over the locally
established backflow level (usually street level). A non-return
valve does not represent a guaranteed backflow seal.
•The attached non-return valve should be installed if the pump
is installed permanently.
•Seal the pipe connections to the pressure port with Teflon
tape.
NOTE: Permanent leakage in this area can lead to
destruction of the non-return valve and of the screwed
connection.
Transportable wet sump installation
In the case of a transportable wet sump installation with hose
connection, the pump must be secured in the shaft to prevent
it from falling over and wandering (e.g. secure chain / rope
with slight pre-tension).
NOTE: When used in a sump without a firm base, the
pump must be put on a sufficiently large plate or hung
from a rope or a chain in a suitable position.
