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.
Features and 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
- Customised designs are available on request
