NOTICE!
Risk of severe material damage due to cavitation!
Cavitation can cause permanent damage to the Börger machine.
— In order to avoid cavitation, the Börger machine should only
have to negotiate a minimal priming height or no priming
height at all.
— The NPSH value on the system (NPSH
avail.
/ NPSH
A
) must
always be sufficiently larger than the required NPSH value on
the pump (NPSH
req.
/ NPSH
R
). The following applies here:
NPSH
avail.
> NPSH
req.
+ 0.5 m (1.64 ft)
and/or NPSH
A
>
NPSH
R
+ 0.5 m (1.64 ft).
— Depending on the application (e.g. when used with gas-emit-
ting media) and pipe construction, it may be advisable to
equip the pipe system with vents at high points.
— Ensure that no pockets of air can build up upstream or
downstream of the pump.
Suitable seals are required for installing the inlet and outlet pipe
connectors to the pipes / hoses, i.e. gaskets are required on flange
connections. These must be resistant against the medium.
The type, design, nominal diameter and nominal pressure of the
connection flanges (or any special connections) are specified in
the order confirmation / data sheet. Only suitable counter flanges /
connectors may be attached in combination with the appropriate
seals.
The pipes to be connected must correspond to the specifications in
the order (material, DN, PN, NPSH
A
value etc.).
