Capacity range of single pump: 260 – 2,100 l/h, 12 – 4 bar
The modular construction of the diaphragm metering pump Makro TZ with adjustable eccentric drive mechanism and mechanically deflected multi-layer safety diaphragm makes it wonderfully adaptable to the capacity requirements of the respective application.
Greater safety in continuous operation through mechanically deflected multi-layer safety diaphragm
The diaphragm metering pump Makro TZ (TZMb) has an adjustable eccentric drive mechanism and, together with the Makro TZ plunger metering pump, forms a range of drive mechanisms with stroke lengths of 10 and/or 20 mm. This covers the capacity range from 8 to 2,100 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.
Excellent process safety and reliability:
- Patented multi-layer safety diaphragm with integral diaphragm rupture warning system
- Metering reproducibility is better than ± 2% within the 30 – 100% stroke length range under defined conditions and with correct installation
- 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
- Metering of reactants and catalysts in the chemical industry
- Level-dependent metering of additives in industrial production engineering

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 94/9/EC 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.
