ProMinent - Model HYDRO Classic -Hydraulic Diaphragm Metering Pump
Capacity range of single-head pump: 3 – 1450 l/h, 100 – 7 bar. As an extremely robust hydraulic diaphragm metering pump, the HYDRO range meets the most exacting safety requirements. Its modular construction, with either one or two dosing heads, 4 gear ratios, 2 dosing head sizes and 3 dosing head materials, offers a very high degree of flexibility in terms of areas of application.
For flexible metering with excellent process reliability in the medium pressure range.
The hydraulic diaphragm metering pump HYDRO with its HP2a, HP3a and HP4a product ranges forms an integrated product range with stroke lengths of 15 or 20 mm. This covers the capacity range from 3 to 1450 l/h at 100 – 7 bar. A wide range of power end versions is available, including some for use in areas at risk from explosion with ATEX certification.
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 20-100% stroke volume range under defined conditions and with proper 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 5 metering units, even with different pump capacities, in multiple pump systems
- 5 different gear ratios are available
