Oil & Gas

Mixers for the petrochemical industry


Within the scope of the highly demanding petrochemical industry, the large range of PRO-DO-MIX® products, all ATEX certifiable, ensures efficiency and precision in the various Oil & Gas industry processes.

All PRO-DO-MIX® solutions can be modified to suit the specific needs of each process to be managed: this ensures a virtually unlimited product range, capable of responding to even the most demanding requirements.

The close collaboration with NOV/Chemineer has resulted in additions of the highest technical value to the product portfolio, such as the ATEX Chemineer top-entry and side-entry agitators, Kenics static mixers, Kenics heat exchangers and Greerco colloid mills.

    Impellers

    The very heart of every vertical agitator

    Thanks to our technical expertise as well as an in-depth knowledge of mechanics and fluid-dynamics, we have developed a complete range of impellers – made with stainless steel or other high-quality materials – in order to fulfil every mixing process.

    4PBT45°

    Pitched Blade Agitator

    It is widely used in a broad range of applications due to its efficiency and cost-effectiveness. Within Water Treatment, pitched blade impellers are perfect for polyelectrolyte preparation and maturation, primary neutralization and pH adjustment.

    It can be manufactured with different diameters, 200 to 2000 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.

    3PM-0030 EVOLUTION

    Impellers with high hydrodynamic profile

    Three-blade impeller with high hydrodynamic profile. It is the “evolution” of Hurricane. Its internal velocity gradient, constant from the centre to the edge of the blade, allows the positioning of an impeller with large diameter very close to the bottom of the tank. That makes Evolution perfect for applications that require the mixer’s continuous operation during the total draw-off of the tank.

    It can be manufactured with different diameters, 1650 to 3500 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.

    3PM-0134 HURRICANE

    Flash Mixing Impellers

    High-efficiency three-blade impeller with high hydrodynamic profile. Thanks to its high flow rate, it is particularly suitable for flash mixing, sludge and solid suspension, equalization, etc.

    It can be manufactured with different diameters, 900 to 1500 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.

    2PM-0650 PREMIUM

    Flocculation Mixer

    Flocculant mixing system with two-blade impeller. Thanks to its high hydrodynamic profile with wide blade surface, has the highest flow rate at the lowest peripheral speed. This design is aimed to prevent the fluid coming out from one blade to immediately meet the second blade.

    Therefore, it is perfect when managing very delicate applications, where the fluid needs to be handled very gently and carefully. That is why Premium is specific for flocculation.

    It can be manufactured with different diameters, 800 to 3000 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.
