Diaphragm Metering Pump Makro TZ

Capacity range of single head pump: 260 – 2,100 l/h, 12 – 4 bar

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.

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

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
