Hydraulic Diaphragm Metering Pump Orlita® Evolution 3

Capacity range of single pump: 21 – 1,330 l/h, 400 – 18 bar

The Orlita® Evolution 3 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 layer control protects against impermissible operating statuses (e.g. no damage in the event of a blockage on the suction or discharge side)
  • Continuous bleeding of the oil chamber ensures reliable operation

Excellent flexibility:

  • The modular construction with single and multiple pump versions permits a wide range of applications. In multiple pump systems up to 5 metering units can be combined, including units with different pump capacities
  • 7 different gear ratios are available; in single pumps the drive arrangement can be either vertical or horizontal
  • Trailer: The new Orlita® Evolution - Takes a forward leap

  • Process Metering Pump Orlita® Evolution: Maximum process reliability

  • Process Metering Pump Orlita® Evolution: Excellent flexibility

  • Process Metering Pump Orlita® Evolution: Design and Technology

Field of application

  • Oil and gas industry
  • Volume-proportional metering of chemicals/additives in the treatment of boiler feed water
  • Metering of reactants and catalysts in the chemical industry
  • Level-dependent metering of auxiliary agents in industrial production engineering, for instance hot wax metering in the production of adhesive strips
