Hydraulic Diaphragm Metering Pump Orlita® Evolution 3

Hydraulic Diaphragm Metering Pump Orlita® Evolution 3

Maximum process reliability and flexibility
Capacity range of single pump: 21 - 1,330 l/h, 400 - 18 bar

The Orlita® Evolution 3 meets the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump. It stands out, among other things, thanks to its PTFE multi-layer diaphragm with integral diaphragm rupture warning system. Its modular construction offers extremely good flexibility in terms of applications.

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 impermissible operating statuses (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 oil chamber ensures reliable operation

Excellent flexibility:

  • The modular construction with single and multiple pump versions permits a wide range of applications, with up to 5 metering units, even with different pump capacities, which can be combined with multiple pump systems
  • 7 different gear ratios are available
  • Power end configuration ideal for installation in any position (vertical or horizontal)
  • Customised designs are available on request

 

Technical details

  • Stroke length: 0 - 25 mm, Rod force:  8,000 N
  • Stroke length adjustment: 0 – 100 %
  • Stroke length adjustment: manually by means of a manual adjustment wheel and scaled display (optionally with electric actuator or control drive)
  • Metering reproducibility is better than ± 1 % within the 10 – 100 % stroke length range under defined conditions and with correct installation
  • PTFE multi-layer diaphragm with electrical diaphragm rupture warning system via a contact
  • Integrated hydraulic relief and bleed valve
  • Wetted materials: Stainless steel 1.4404, special designs are available on request
  • A wide range of power end versions is available: Three-phase standard motors also for use in Exe and Exde areas and different flange designs for use in customer-specific motors
  • Degree of protection: IP 55
  • Design in compliance with API 675 among others

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
