Article no. 5356080241 Lattec p/n : 60026782
The spare part consists of the tube with a threaded fitting mounted in one end.
The same spare part is used for the VMS and Parlour installations and on both HN1 and HN2 versions of
the sample intake.
3.1.6.1 Removal of the old tube:
Unscrew the 4 screws holding the milk pump housing, and remove the housing from the motor shaft. Take
the two parts of the pump housing apart and remove the tube. Ensure that the fiber washers are in place at
each side of the pump rotor. Note that the rotor shaft is not symmetrical it has to be oriented so that the end
with the groove will engage with the shaft on the motor. Clean the pump housings and the rotor if
necessary.
