NOV / Chemineer / Greerco in-line mixers


NOV / Chemineer / Greerco in-line mixers

NOV (National Oilwell Varco) / Greerco in-line or dynamic mixers provide an extraordinary mixing flow rate and are able to handle high viscosity products. The versatile design enables different combinations resulting in a wide range of configurations (e.g. single or multiple rotors / stators, different bore dimensions, etc.).

PRO-DO-MIX® is the official distributor in Italy for NOV / Chemineer / Greerco and can offer assistance and expertise in supplying dynamic mixers, colloid mills and high shear mixers, as well as spare parts for the maintenance of existing units.

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.

3PM-1084 EXCELLENT

Industrial Mixing Impellers

Three-blade impeller with high hydrodynamic profile. Within our industrial impeller models, it has the lowest torque for the same flow rate. Moreover, it can create the highest flow rate with the lowest peripheral speed.

It is perfect as flow-maker, for high head values in recirculation.

It can be manufactured with different diameters, 200 to 3500 mm.

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

3PM-1084 EXCELLENT

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.

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-0030 EVOLUTION

3PM-0242 MASTER

Impellers for nitrification and denitrification in wastewater treatment

Three-blade impeller with high hydrodynamic profile. Due to its special design, it can produce a centrifugal effect for which the impeller can be defined self-cleaning, thanks to this anti-clogging effect.

It is specific for nitrification/denitrification, anaerobic digestion, mixing in anoxic systems and other applications with presence of fibres.

It can be manufactured with different diameters, 1600 to 3500 mm.

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

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.

MARINE PROPELLER

Helical Blade Mixer

This helical type impeller is very versatile, generally installed in fast direct mixers. Very common in small preparations of chemicals.

It is manufactured from casting in proprietary moulds.

It can be manufactured with different diameters, 90 to 160 mm diameter.

Available in 2 material options, polypropylene (PP) and stainless steel (SS 316L).

COWLES

High Shear Impellers

Perfect when dealing with high viscosities, cowles agitators are typically used in paints or detergents industry. Their design, combined with the high shear, allow the product dispersion and foster a quick dissolution.

They can be manufactured with different diameters, 75 to 750 mm.

Different joint options are available.

ANCHOR

Impeller for high viscosity fluids

Generally used within food & beverage and cosmetics industry to manage high viscosity products or to foster heat exchange.

It is common within the pharmaceutical industry as well, in processes such as crystallization.

Moreover, it is often used as universal rotor in small tanks for multi-stage applications.

The engineering and the manufacturing of this anchor type impeller are directly related to the tank features.
