Hydraulic Diaphragm Metering Pump HYDRO Classic

  • Anasayfa >
  • Hydraulic Diaphragm Metering Pump HYDRO Classic

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.

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 20-100 % stroke volume 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 5 metering units, even with different pump capacities, in multiple pump systems
  • 5 different gear ratios are available

Technical Details

  • Stroke length: 15 mm (HP2a, HP3a), 20 mm (HP4a)
  • Rod force: 2000 N (HP2a), 4200 N (HP3a), 5800 N (HP4a)
  • Stroke volume adjustment range: 0 – 100%
  • Stroke volume adjustment: manually using scaled rotary dial (optionally with electric actuator or control drive)
  • The dosing precision is better than ± 1 % within the 20 to 100% stroke volume 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, Hastelloy C.
  • A wide range of power end/drive versions is available: Three-phase 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
