The above-mentioned max. working pressure is
NOT valid for pumps approved by a classification
society. Pumps approved by classification societies have been pressure tested according to the
requirements of these societies, i.e. a test pressure of 1.5 x the permissible working pressure. The
test pressure is stated in the test certificate and stamped into the discharge flange of the pump.
