14. FORCES AND MOMENTS AT THE PUMP FLANGES
All of the applied loads if 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 limited 1.4 times of the maximum allowablevalue,
 The actual forces and moments acting on each flange, should provide the following formula:

Forces at the pump flanges were calculated according to TS 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.
