Page 17: Functional Description
The adjustment of the stroke length takes place via a finely adjustable change to the eccentricity of the shift ring (TZ) (5) which influences the oscillating stroke movement. This drive principle ensures a harmonic, purely sinusoidal stroke movement for each stroke length adjustment. - Page 18 Functional description P_MA_0029_SW Fig. 7: Cross-section through the liquid end Discharge valve Metering diaphragm Dosing head Suction valve Diaphragm rupture signaller Diaphragm rupture warning system func‐ The diaphragm rupture warning system monitors the leak-tightness of the tional description multi-layer diaphragm.
