3.2 Resistance
The compatibility of the pump tube for the medium in question
must be checked with the aid of a resistance table (e.g. Lutz
resistance table) and the
table 1 (see page 24)
of materials.
When cleaning the pump, ensure that all parts in contact with
the cleaning agent are also compatible with it!
3.3 Operating temperature
The temperature of the medium must not exceed the values
specified in
table 2 (see page 24)
.
4. Starting up
4.1 Installation of the B70V
The three-phase drives are connected with the pump by means
of a quick fastener.
Inside of the fastening screw threads of the motors are pre-
mounted for this purpose two positioning pins
(see Fig. 1
- Item 1)
and two locking screws
(see Fig. 1 – Item 2)
.
Before assembly the jaw-type coupling must be adjusted at the
motor- and pump-side
(see Fig. 1 - Item 3)
.
Attach the motor onto the pump . The both locking screws here
must be in accordance with the large bores at the flange of the
pump
(see Fig. 1 - Item 4)
.
After a clockwise turning of the motor at block position
(see
Fig. 1.1 - Item 1)
the both locking screws can be tightened
(see Fig. 1.1 - Item 2)
.
4.2 Installation of the B70V-SR
The motor is mounted on the pump tube. The motor must be
turned slightly to ensure that the driver engages correctly in
the coupling of the pump tube. The motor and pump tube are
then firmly connected by means of the handwheel (right-hand
thread)
(see Fig. 2)
.

Ensure that the pump is fitted correctly and securely.
4.3 Electrical connection of three-phase motors
The electrical connection may only be carried out by
trained qualified personnel. Following regulations must
be observed:
- All works must only be carried out in voltage-free condition
of the motor.
If available, set the protection switch mounted to OFF.
- Mains voltage and frequency are as specified on the rating
plate
(see Fig. 3)
.
- Dimension of the connecting cable must be adjusted to the
nominal current.
- The insulation of the connecting cable must be adjusted to
the environmental conditions.
4.4 Direction of rotation
The motor must rotate in the direction indicated by the arrow
on the adapter. Reverse the motor connections if necessary
(see Fig. 4)
.
