Plunger Metering Pump Makro/ 5

Capacity range of single head 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 M5Ka together with the MAKRO hydraulic diaphragm and diaphragm metering pumps form a range of drive mechanisms with stroke lengths of 20 or 50 mm. A wide range of drive versions is available for use in areas at risk from explosion 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

    Control of MAKRO M5Ka metering pumps

    Stroke length controller MAKRO M5Ka

    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, equipped with 2 limit switches for min./max. position, degree of protection: IP 54. Electrical connection 230 V (±10%), 50/60 Hz, approx. 40 W mechanical stroke length display fitted on the Makro/ 5 drive.

    Special voltage/higher degrees of protection/explosion protection available on request.

    Design with:

    0/4-20 mA standard current input (corresponds to stroke length 0-100%); internal switch-over for manual/automatic operation, key switch for stroke adjustment in manual mode. 0/4-20 mA actual value output for remote display.

    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.

    Approved for explosion protection operation with degree of protection EEx ia II C T6.
