14. FORCES AND MOMENTS AT THE PUMP FLANGES
All of the applied load sif not reached the maximum allowable value, to
provide that the following additional conditions, one of these loads may
exceed the normal limit:
Any component of a force or a moment, must be limited1.4times of
the maximum allowable value,
The actual force sand moments acting on each flange, should provide
the following formula:

Table 6 - Forces and Moments at The Pump Flanges
Forces at the pump flanges were calculated according toTS EN ISO 5199 standard. The calculations are valid for the materials of cast iron and
bronze. Forces and moments at the flanges that made of stainless material will be approximately twice as moments in the table.
