Hydraulic diaphragm metering pump Orlita Evolution E1Sa

Capacity range of single-head pump: 0.8 – 126 l/h, 260 – 28 bar

As an extremely robust hydraulic diaphragm metering pump, the ORLITA Evolution E1Sa meets the most exacting safety requirements. It is characterised by its PTFE multi-layer diaphragm with integral diaphragm rupture warning / signalling system and unique diaphragm position control.

Product description

Safety processes as standard.

The ORLITA Evolution 1S together with the ORLITA Evolution hydraulic diaphragm metering pumps EF1a, EF2a and EF4a form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range from 3 to 7400 l/h at 400 – 10 bar. A wide range of drive versions is available, including some for use in Zone 1 or Zone 2 areas at risk from explosion with ATEX certification. 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 / signalling 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 adjustment range under certain defined conditions and with proper installation
  • Continuous bleeding of the oil chamber ensures reliable operation

Field of application

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

    Technical Details

    • Stroke length: 0 - 16 mm
    • Rod force: 2000 N
    • Stroke length adjustment range: 0 – 100%. Stroke length adjustment: manually using manual adjustment wheel and scaled display (optionally with electric actuator or control drive). A fixed stroke variant in accordance with API 674 is also available as an alternative
    • 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 / signalling system via a contact
    • Integrated hydraulic relief and bleed valve
    • Wetted materials:  Stainless steel 1.4404, special designs available on request Plastics PVC, PVDF, special designs available on request
    • A wide range of drive versions is available: Three-phase AC standard motors also for use in areas at risk from explosion, different flange designs for use of customer-specific motors
    • Degree of protection: IP 55
    • Design in compliance with API 675 / API 674 among others
