This assembly is composed of a gear pump, an electric motor, a manometer and a valve block.
Thanks to a by-pass it is possible to regulate the working pressure in accordance with the requirements of the system to which
the pump is connected.
Also included in the valve block is a non-return valve or alternatively a release valve so that it can be adapted for use with the
different DROPSA systems (line 01, line 26, 33V System) or on other systems of a similar nature.
It is also possible to order separately an intake filter with a dip tube (400 mesh/cm2 filtering grade 260) of an overall length
variable between 100 and 455 mm depending on the differing requirements of the installation).
THE MOTOR VOLTAGE MUST ALWAYS BE STATED AT THE TIME OF ORDERING.
