Pump connections to an installation
Alcatel Vacuum Technology France - ATP User’s Manual

GB 00410 - Edition 01 - March 97
The pump can operate in
any position
The connection of the pump
to the installation must be
sufficiently rigid.
For this, reduce the
following as much as
possible:
- dimensions
a
and
b
and
the flexibility of the
connection plate;
- the overhang
c
between
the pump and its anchor
point.
The equipment attachment devices should be sufficiently rigid to prevent
potential risks in the event of failure of a rotary component or a violent shock
on the pump (exceptional phenomena).
For this, use the rotary flange attachment holes.
If the intake flange is attached with grips, use:
- at least 3 grips for secondary pump
≤
150 l/s;
- at least 6 grips for secondary pump > 150 l/s.
The dimensions of the connection parts should be studied
carefully:
