Hydraulic Diaphragm Metering Pump Makro/ 5

Capacity range of single pump: 450 – 6,108 l/h, 25 – 6 bar

The robust hydraulic diaphragm metering pump Makro/ 5 guarantees outstanding process reliability. Its modular construction offers extremely good flexibility and a large range of drive versions are available.

Excellent Feed Rates in the Low-Pressure Range

The MAKRO hydraulic diaphragm metering pump (M5Ha) together with the MAKRO diaphragm and plunger metering pumps form an integrated product range with stroke lengths of 20 or 50 mm. This covers the capacity range from 38 to 6108 l/h at 320 – 4 bar. A wide range of drive versions is available for use in areas at risk from explosion with ATEX certification. The MAKRO product range is designed to comply with API 675 among others.

Your benefits

Excellent process reliability:

  • PTFE multi-layer diaphragm with integral diaphragm rupture warning / signalling system
  • Integral hydraulic relief valve
  • The dosing precision is better than ± 1 % within the 10-100 % 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

Technical Details

  • Stroke length: 0 – 50 mm, Rod force: 10000 N
  • Stroke length adjustment range: 0 – 100%
  • Stroke length adjustment: manually using manual adjustment wheel and scaled display (optionally with electric actuator or control drive)
  • The dosing precision is better than ± 1 % within the 10 – 100% stroke length range under defined conditions and with correct installation
  • PTFE multi-layer diaphragm with electrical diaphragm rupture warning / signalling system via a contact
  • Integrated hydraulic relief and vent valve
  • Wetted materials: PVDF, PTFE+25% carbon, stainless steel 1.4571, special materials are available on request
  • A wide range of power end/drive versions is available: Three-phase standard AC motors, motors for use in areas at risk from explosion and different flange designs for use in customer-specific motors
  • Degree of protection: IP 55
  • Design in compliance with API 675 among others
