Diaphragm Metering Pump Makro/ 5

Capacity range of single head pump: 1,540 – 4,000 l/h; 4 bar

The diaphragm metering pump Makro/ 5 is used to meter reactants and catalysts in the chemical industry. Thanks to its modular construction, it can adapt outstandingly to the actual requirements of each application.

Product description

It is not possible to do more with a mechanically deflected diaphragm

The diaphragm metering pump Makro/ 5 (M5Ma), 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 6,000 l/h at 320 – 4 bar. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification.

Your benefits

Process reliability:

  • Metering reproducibility is better than ± 2% within the 30-100% 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

Technical Details

  • Stroke length: 0-20 mm, Rod force: 10,000 N
  • Stroke length adjustment range: 0 – 100%
  • Stroke length adjustment: manually by means of a manual adjustment wheel and scaled display in 0.5% increments (optionally with electric actuator or control drive)
  • Metering reproducibility is better than ± 2% within the 30 – 100% stroke length range under defined conditions and with correct installation. Observe the information in the operating instructions
  • Wetted materials: Polypropylene, PVC, PTFE+25% carbon, stainless steel 1.4571, special materials are available on request

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.
