Control of Makro/5 Hydraulic Diaphragm Metering Pumps
Makro/ 5 stroke length controller
Control drive consisting of an actuator with servomotor and integral microprocessor controller for stroke length adjustment via a standard signal. Actuating period approx. 100 sec for 100% stroke length, including 2 limit switches for min./max. position, IP 54 degree of protection. Electrical connection 230 V (±10%), 50/60 Hz, 40 W mechanical stroke length display fitted on the Makro/ 5 power end.
Special voltage/higher degrees of protection/explosion protection on request.
Version with:
Standard signal current input 0/4-20 mA, corresponds to stroke length 0 - -100%; internal switch for manual /automatic operation, key switch for stroke adjustment in manual mode. Actual value output 0/4-20 mA for remote display.
Speed controllers with frequency converter (identity code specification Z)
The speed controller (complete) comprises a frequency converter and a variable speed motor (see also identity code specification R). The frequency converter is accommodated in an IP 55 rated protective housing with integral control unit and main switch, suitable for max. motor power 0.37/0.75/1.1 kW.
Externally controllable with 0/4-20 mA or 0-10 V corresponding to 0-50 (60) Hz output frequency.
Stroke sensor with Namur signal
Mounting on the crank drive mechanism of the Makro/ 5 gearbox. For precise measurement of each metering stroke, comprising electronic cams and inductive proximity switches, switching signal according to Namur. In combination with electronic pre-selection meters suitable for batch metering or proportional metering in conjunction with proportional control.
Retrospective fitting only possible in the factory.

Motor data sheets can be requested for more information. Motors for Sigma basic pumps, special motors or special motor flanges are available on request.
The motors are designed in compliance with the Ecodesign Directive 2009/125/EC.
Information for use in areas at risk from explosion
Only use pumps with the appropriate labelling in line with the ATEX Directive 2014/34/EU in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label corresponds to or is better than the conditions prevalent in the intended field of application.
