Hydraulic Diaphragm Metering Pump Orlita® Evolution 2

Capacity range of single pump: 6 – 900 l/h; 400 – 11 bar

The Orlita® Evolution 2 meets the highest safety requirements as an extremely robust hydraulic diaphragm metering pump. It stands out, thanks to its PTFE multi-layer diaphragm with integral diaphragm rupture warning system and unique diaphragm position control.

Product description

Maximum process reliability and flexibility.

The Orlita® Evolution hydraulic diaphragm metering pump range of EF1a, EF2a, EF3a and EF4a form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range of 3 to 7,400 l/h at 400 – 10 bar. A wide range of drive versions is available, including some with ATEX certification for use in Zone 1 or Zone 2 areas at risk from explosion. The Orlita® Evolution product range is designed to comply with API 675.

Your benefits

Maximum process reliability:

  • PTFE multi-layer diaphragm with integral diaphragm rupture warning system
  • Integral hydraulic relief valve
  • The new diaphragm position control protects against operating faults (e. g. no damage in the event of a blockage on the suction or discharge side)
  • Metering reproducibility is better than ± 1% within the 10 – 100% stroke length range under defined conditions and with correct installation
  • Continuous bleeding of the hydraulic oil chamber ensures reliable operation

Excellent flexibility:

  • The modular compact construction with single and multiple pump versions allows for a wide range of applications, also for multiple pump systems, whereas up to 5 metering units, even with different pump capacities, can be combined.
