Microfluidics produces patented Microfluidizer ® Processor equipment with high-pressure, fixed-geometry interaction chambers that impart high shear rates to product formulations. The M-700 generates up to 40,000 psi operating pressure for premium results at an affordable cost.

Key benefits:

• Repeatable, uniform particle size results to submicron distributions with guaranteed scaleup from R&D to full production
• Continuous or batch mode; the model M-700 Series can process at a wide range of pressures and flows

Key features:

• Proven to be highly reliable at operating pressures up to 40,000 psi in pilot and production environments.
• Generates the highest shear rates of any fluid processor on the market today. This results most often, in achieving desired product quality in a single pass.
  
• Patented interaction chamber — wear-resistant construction; geometrically fixed design ensures that entire product stream will encounter equal energy per unit fluid volume.
  
• Model 7250 units are standard with two syncronized intensifier pumps for increased flow rates.
  
• In-line cleaning with no disassembly required
  
• All stainless steel construction.

M-700 Series Applications

The M-700 series offers pilot and production performance levels with specific features amenable to industrial chemical processing of such materials as coatings, waxes, inks, pigments, sealants, etc. The M-700 utilizes our patented Microfluidizer® process to deliver the finest and most uniform distribution of submicron particle size at the highest shear rates available of any processor technology. Emulsions and suspensions are more stable, and the performance of your final products are superior.

The three M-700 models have the same enclosure size. The 7115 incorporates a 15 HP motor and a single intensifier pump. Pressure, flow, and resultant shear rates are selectable, and your choice of available interaction chambers help you achieve optimum results.

Models 7125 and 7250 house 25-HP and 50-HP motors respectively. The 7250 can be fitted with one or two intensifier pumps that can be operated with independent product streams, pressures and flow rates. This independent operation enables double-volume processing of the same product, simultaneous processing of two different products, or the same product run in series through one pump and then the other. One pump can run alone while the other is being cleaned or serviced.

Operating Principle

Each M-700 series machine contains an electric-hydraulic system providing power to one or two single-acting intensifier pumps, depending on the model selected. The pump amplifies the hydraulic pressure to the selected level which, in turn, imparts that pressure to the product stream. Process pressures range from 2,500 to 40,000 psi, resulting in high velocity, high shear process streams.

The intensifier pump is designed to supply the desired pressure at a constant rate to the product stream. As the pump travels through its pressure stroke, it drives the product through precisely defined fixed-geometry microchannels within the interaction chamber. As a result, the product stream accelerates to high velocities, creating shear rates within the product stream that are orders of magnitude greater than any other conventional means. All of the product experiences identical processing conditions, producing the desired results, including: uniform particle and droplet size reduction (often submicron), deagglomeration and high yield cell disruption.

At the end of the power stroke, the intensifier pump reverses direction and the new volume of product is drawn in. The intensifier pump again reverses direction and pressurizes the new volume of product, repeating the process.
Upon exiting the interaction chamber, the product may be directed through an optional heat exchanger, recirculated through the system for further processing or directed externally to the next step in the process.
