3. TRANSPORT AND TEMPORARY STORAGE

On principle, the pumps SANIPUMP
top or the handlebar designed for that purpose. Under no circumstances is the pump to be lifted on the
power supply cable !
For temporary storage and conservation, it suffices if the pumps are stored in a cool, dry, frost-protected
and dark place.

4. DESCRIPTION

4.1 Motors

The pumps SANIPUMP
phase asynchronous motor. Temperature sensors, which function as temperature limiters, have been
integrated into each of the three motor windings. If the motor overheats for any reason, the bimetallic
contacts respond to this and the motor is switched off.
The motor is to be restarted solely by hand! However, the motor may only be restarted after an error
analysis has been conducted and the cause of malfunction has been eliminated.
The motors are certified by the BVS - Dortmund and have the following certificates of conformity:
BVS 05 ATEX E 028 X.

4.2 Pumps

The pump housing and the impeller are made of grey cast iron; the cutting device, which is
located in front of the impeller on the suction side, is made of a special alloy. This cutting device
comminutes suspended soils, so that they will not enter the pump and choke it. The pumps are
equipped with a flange DN 50.
4.3 Switching device
The pumps are delivered without switching device.

5. INSTALLATION

- Disconnect the power supply before carrying out any kind of
work on the plant!
- The electrical connections are not to be exposed to humidity!

5.1 Electrical equipment

The AC-powered model of the pump can be operated with an auxiliary switch device which is
equipped with the following elements: main switch, fuses, contactors, thermal motor protection relay,
operating capacitor, restart lockout for the clipping circuit, signal lamps „Betrieb" (operation) and
„Störung" (malfunction), Ex i - relay and a floater for the protection against dry running.
The pump is connected to an earthed wall socket with an earthed type plug by means of the cable which
is con-nected to the switching device.
