Plunger Metering Pump Makro/ 5

Capacity range of single pump: 38 – 6,014 l/h, 320 – 6 bar

The plunger metering pump Makro/ 5 can virtually be used throughout the low-pressure range and its modular construction enables it to be outstandingly adapted to the performance requirements of the respective application.

Product description

Powerful, built to last with a plunger

The plunger metering pump Makro/ 5 (M5ka) together with the Makro/ 5 hydraulic diaphragm and plunger metering pumps form a range of drive mechanisms with stroke lengths of 20 and/or 50 mm. This covers the capacity range from 38 to 6,108 l/h at 320 – 4 bar. A wide range of drive versions is available, including some for use in Exe and Exde areas with ATEX certification.

Your benefits

Process reliability:

  • Metering reproducibility is better than ± 0.5 % within the 10 – 100% stroke length range under defined conditions and with correct installation

Excellent flexibility:

  • The modular construction with single and double head versions permits a wide range of applications, with the double head designs being operated in push-pull mode
  • It is possible to combine up to 4 metering units, even with different pump capacities, in multiple pump systems
  • 5 different gear ratios are available
  • Customised designs are available on request

Field of application

  • Volume-proportional metering of chemicals/additives in water treatment

    Makro/ 5 Pump Control

    Stroke length variable speed drive Makro/ 5

    Variable speed drive consisting of actuator with motor actuator and integrated microprocessor controller for stroke length adjustment via a standard signal. Actuating time approx. 100 sec. for 100% stroke length, equipped with 2 limit switches for min./max. position, IP rating: IP 52. Electrical connection 230 V (±10%), 50/60 Hz, approx. 40 W, mech. stroke position indicator present at drive Makro/ 5.

    Special voltage/higher IP ratings/Ex protection on request.

    Includes:

    Standard 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 operation mode. Actual value output 0/4-20 mA for remote display.

    Frequency converter for speed control in metal housing, IP rating 54

    Frequency converter installed in protective housing IP 54 with integrated control unit and main switch suitable for the motor output stated in the following.

    Externally controllable with 0/4-20 mA or 0-10V corresponding to 0-50 (60) Hz output frequency.

    Integrated control unit with numerous functions, such as toggling external/internal control. With internal control, frequency setting is via arrow keys, error message on multi lingual display etc.

    Including evaluator for temperature monitoring of the motor (thermistor protection).

    Stroke sensor with namur signal

    Mounted on the crank drive of the Makro/5 gearbox. For precise detection of each metering stroke, consisting of actuating cams and inductive proximity switch, switching signal according to Namur. Combined with electronic preselection counters suitable for batch metering or proportional metering in connection with the proportional control.

    Retrofitting is only possible on factory premises.

    Approved for ex-proof operation with IP rating EEx ia II C T6.
