Table B
• The OBL's unique (patented) mechanical diaphragm
design ensures controlled volumetric displacement, giving
plunger-like performances.
Thus the flow rate is virtually unaffected by the working
pressure variations.
DIAPHRAGM STRUCTURE
• In table B are described motors installed on MB/MC pumps.
Endless screw is directly keyed on extended motor shaft.
MOTOR CHARACTERISTICS ACCORDING TO THE PUMP SIZE
• The adjustment of the diaphragm stroke is stepless and regular, and can be
carried out any time, i.e. when the pump stands still or is running (fig.5).
