Diaphragm metering pump Makro TZ

The modular construction of the diaphragm metering pump Makro TZMb with adjustable eccentric drive mechanism and mechanically deflected multi-layer safety diaphragm enables it to be outstandingly adapted to the performance requirements of the respective application.

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.

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

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: 0-10 mm, Rod force: 8,000 N
• Stroke length adjustment range: 0 – 100%
• Stroke length adjustment: manually by means of scaled rotary dial 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
• Patented multi-layer safety diaphragm with optical diaphragm rupture display (optionally with electrical diaphragm rupture warning system / warning via a contact)
• Wetted materials: polypropylene, PVC, PTFE+25% carbon, stainless steel 1.4571. Special materials are available on request
• A wide range of drive versions is available: three-phase standard or 1-phase AC motor, motors for use in areas at risk from explosion, different flange designs for use of customer-specific motors
• Degree of protection: IP 55
• Salt water-resistant, acrylic resin-coated cast aluminium housing
• For reasons of safety, provide suitable overload protection mechanisms during the installation of all mechanically actuated diaphragm metering pumps.
