Excellent feed rates in the low pressure range
The Makro/ 5 hydraulic diaphragm metering pump (M5Ha) together with the Makro/ 5 diaphragm and plunger metering pumps form an integrated product range with stroke lengths of 20 and/or 50 mm. This covers the capacity range from 38 to 6,108 l/h at 320 – 4 bar. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification. The Makro/ 5 product range is designed to comply with API 675 among others.
Your benefits
Excellent process safety and reliability:
- PTFE multi-layer diaphragm with integral diaphragm rupture warning system
- Integral hydraulic relief valve
- Metering reproducibility 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 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
