It is possible to increase the suction valve ball
stroke placing the stop ball pin (O6) on the upper
holes of the suction valve. This modification is
suggested in case of very viscous products. The
same operation can be performed on the piston rod.
•
Extract the piston rod from the bottom.
•
Disassemble the piston rod and replace the gaskets worn.
•
Remove the upper gaskets, if necessary, to be replaced.
•
For the correct reassembling see illustration and the exploded
