The standard delivery capacity ratings are covered by two model series, Hydro/2 in the capacity range from 60 l/h at 25 bar back pressure up to 22 l/h at 64 bar back pressure and Hydro/3 with a delivery rate of 150 l/h at 25 bar back pressure up to 60 l/h at 64 back pressure with application-oriented performance graduation in eight stages.
The main hydraulic pump is driven as standard with a 0.37/0.75 kW; 230/400 V, 50/60 Hz three-phase AC motor suitable for worldwide applications. The stroke length is 15 mm and can be adjusted to an accuracy of 1%. Under defined conditions, the metering reproducibility is better than ± 1% in the stroke length range from 20-100%.
The pumps can be equipped with a second liquid end to increase the pump capacity. The metering rate can be further increased with hydraulic add-on pumps.
The metering capacity can be controlled by means of a stroke length actuator or a stroke length variable-speed drive. The actuator with servo motor is used for automatic stroke length adjustment with an actuating time of 1 second for 1% stroke length. The variable-speed drive consists of an actuator with servo motor and built-in follow-up control for stroke length adjustment via a standard signal.
