Greater safety in continuous operation through mechanically deflected multi-layer safety diaphragm.
The diaphragm metering pump MAKRO 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 or 20 mm. A wide range of drive versions is available for use in areas at risk from explosion with ATEX certification.
Your benefits
Excellent process reliability:
- Patented multi-layer safety diaphragm with integral diaphragm rupture warning / signalling system
- The dosing precision 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 (boxer principle) 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
The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.
- 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
- Metering of Fluids in Chemical Production
- Incredible versatility: metering pumps in production
- There are various types of metering pumps, but what they all have in common is reliability, robustness and thoroughness. That’s why all our pumps are in demand in chemical production.
- Feed Water Treatment in Energy Generation
- ProMinent-style desalinated boiler feed water
- Our water treatment know-how delivers desalinated and therefore high-quality, ultra-pure boiler feed water. No energy or water is lost with ProMinent.
- Flue Gas Cleaning in Energy Generation
- Flue gas cleaning for fresh air and a clean environment
- ProMinent understands how to incorporate the complex flue gas cleaning process in power plants. Harmful substances are reliably removed from the air before they enter the atmosphere.
- Heap Leaching in Mining
- You can’t go wrong with perfectly metered leaching agents
- ProMinent metering pumps reliably meter aggressive substances such as hydrochloric acid or sulfuric acid without being destroyed in the process. Only the hidden gold, silver, copper etc. is dissolved out of the ore.
- Metering of Fluids
- Incredibly simple and efficient metering of chemicals
- We transport chemicals with ease in any industrial environment: ProMinent solutions store, transfer and meter substances at rates of 0.1 l/h to 100,000 l/h at a pressure of 2 to 3,000 bar.
