Evolution Series

Flow rates from 0.79 to 1,955 gph per head. Operating pressures up to 5,800 psi

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

Product description

Maximum process reliability and flexibility.

The ProMinent Evolution Series pumps are API 675, 3rd Edition compliant and meet the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump design.

Your benefits

  • Flow rates from 0.48 to 1932.48 gph per head
  • Operating Pressures up to 5802 psig
  • Variable eccentric drive for accurate, robust operation and a smaller footprint
  • Four frame sizes to cover a broad range of applications
  • PTFE multi-layer diaphragm with integral diaphragm rupture warning system is standard on all pumps
  • Liquid End Materials in 316ss and Alloy 20, additional materials available on demand
  • Exclusive Diaphragm Position Control protects the pump against operating faults (e.g., no damage in the event of a blockage on either the suction or discharge side). This advance in pump design technology means a more reliable metering pump in every application
  • Metering reproducibility is better than ±1 % within the 10 - 100 % stroke length range under defined conditions and with correct installation
  • Continuous air bleeding of the hydraulic oil chamber ensures reliable operation
  • Integral adjustable internal hydraulic pressure relief valve with features that allow for oil cooling during extended periods of process upset conditions
  • Excellent flexibility
  • The Evolution's modular compact construction allows for a wide range of applications
  • Up to five (5) metering units of identical or varying pump capacities can be multiplexed for the greatest application adaptability
  • A rotatable drive housing allows for installation of motor in a vertical or horizontal position to better meet specific footprint requirements
  • Custom designs are possible to meet a variety of application demands

Field of application

The following list is a general representation of basically suitable applications for this product. Please contact your personal representative to discuss the use of the product in your individual 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

    Metering of Fluids in Chemical Production

    Incredible versatility: metering pumps in production

    There are various types of metering pumps, but what they all have in common is reliability, robustness and thoroughness. That's why all our pumps are in demand in chemical production.

    Inhibitor Metering Offshore

    For smooth oil production

    Our ProMinent metering pumps keep the pipework clear 24 hours a day and protect against corrosion and defects. So the oil can keep flowing.

    Onshore Metering in Gas Pump Stations

    Safety at the borehole

    Flammable methane hydrate at the borehole can be very dangerous. But not with ProMinent metering pumps. By metering fluid into the drilling head, they don't even allow methane hydrate to be produced in the first place.

    Downstream Oil Treatment

    It's all about the oil

    Makro diaphragm metering pumps or even the new Evolution pumps are used for emulsion cracking so that the precious oil is perfectly separated from other substances. The pumps are completely autonomous.

    Feed Water Treatment in Energy Generation

    ProMinent-style desalinated boiler feed water

    Our water treatment know-how delivers desalinated and therefore high-quality, ultra-pure boiler feed water. No energy or water is lost with ProMinent.

    Flue Gas Cleaning in Energy Generation

    Flue gas cleaning for fresh air and a clean environment

    ProMinent understands how to incorporate the complex flue gas cleaning process in power plants. Harmful substances are reliably removed from the air before they enter the atmosphere.

    Metering of Fluids

    Incredibly simple and efficient metering of chemicals

    We transport chemicals with ease in any industrial environment: ProMinent solutions store, transfer and meter substances at rates of 0.1 l/h to 100,000 l/h at a pressure of 2 to 3,000 bar.

    Overview

    Maximum process reliability and flexibility.

    The ProMinent Evolution Series pumps are API 675, 3rd Edition compliant and meet the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump design.

    Your benefits

    • Flow rates from 0.48 to 1932.48 gph per head
    • Operating Pressures up to 5802 psig
    • Variable eccentric drive for accurate, robust operation and a smaller footprint
    • Four frame sizes to cover a broad range of applications
    • PTFE multi-layer diaphragm with integral diaphragm rupture warning system is standard on all pumps
    • Liquid End Materials in 316ss and Alloy 20, additional materials available on demand
    • Exclusive Diaphragm Position Control protects the pump against operating faults (e.g., no damage in the event of a blockage on either the suction or discharge side). This advance in pump design technology means a more reliable metering pump in every application
    • Metering reproducibility is better than ±1 % within the 10 - 100 % stroke length range under defined conditions and with correct installation
    • Continuous air bleeding of the hydraulic oil chamber ensures reliable operation
    • Integral adjustable internal hydraulic pressure relief valve with features that allow for oil cooling during extended periods of process upset conditions
    • Excellent flexibility
    • The Evolution's modular compact construction allows for a wide range of applications
    • Up to five (5) metering units of identical or varying pump capacities can be multiplexed for the greatest application adaptability
    • A rotatable drive housing allows for installation of motor in a vertical or horizontal position to better meet specific footprint requirements
    • Custom designs are possible to meet a variety of application demands
