The pumps of this range allow to the removal of the
pump rotor whilst leaving the pump casing
connected to the suction and discharge pipework.

The pump must be stored in a non-explosive,

ventilated location, sheltered from bad weather, dust
and vibrations.

The reliability of the delivered machine can only be
ensured if it is used according to the conditions
given in this manual.

The maximum values specified in this manual must
never be exceeded.
