5.2.2.2 Slow suction SS1
The Slow Suction 1 (SS) mode reduces the speed during the suction cycle while increasing the pressure
cycle to compensate for the loss of flow. In this way, the accuracy of the dosing of viscous liquids is
improved, since the risk of cavitation and incomplete filling of the head is reduced. Suction is carried out
at 50% of the speed of Standard mode, but the final flow is reduced to only 75%.
5.2.2.3 Slow suction SS2
The Slow Suction 2 (SS) mode reduces the speed during the suction and discharge cycle.The suction
operation is as described for Slow Suction 1, and the discharge cycle speed is also reduced to 50% to
avoid overpressure in long deliveries. In this mode the flow is reduced to 50%
5.2.2.1 Low pulsation standard
The Standard ST mode is the normal operating mode where the doser has symmetrical behaviour during
suction and discharge of the product while working at maximum capacity. As the flow rate is reduced, the
discharge cycle is extended, keeping the suction duration constant.
