Homogenizing, Dispersing, Emulsifying and Dissolving

Our new unit enables you to produce multiphase products of consistently high quality, time after time

The principle is really quite simple. The new, efficient mixing method is based on the proven centrifugal pumps of the Fristam FP range. Instead of the impeller, a rotor/stator system, operating at tip speeds of up to 38 m/s, draws inhomogeneous media through shearing clearances of just 0.3 mm Thanks to the extremely high flow rates in the rotor/stator system and the high shear rate of up to 125,000 1/s, a high-performance blending of multiphase products is achieved. The result: Inseparable emulsions and end products of incomparable homogenity. The smooth operational performance achieved by this system conforms with the unique precision and quality you have come to expect from all Fristam components. The stator: The media are drawn through shear clearances of 3/10 mm. Disintegrated into the smallest particles, these are blended thoroughly until inseparable. Since application vary in type and complexity, we offer customized solutions ranging from the small single unit to largescale inline installations, as well as expect engineering consultation and support. Since application vary in type and complexity, we offer customized solutions ranging from the small single unit to largescale inline installations, as well as expect engineering consultation and support. Concentrated: With the Shearpump, it is easy to achieve highly concentrated solutions and to process stabilizers to highly viscous materials.

The powder mixer: The compact framed unit described here requires very little space to operate fully, even inline, and is easily integrated into existing systems and processes.

Pump ranges
The FSPE 35 range with motors of 3.0 to 30.0 kW and rotor diameters of 145 to 250 mm are particularly suitable for high viscosities and throughput rates


The FPM 7 range with motors of 2.2 to 18.5 kW and rotor daimeters of 130 to 195 mm is the optimum choice for handling medium viscosities and throughput rates

Using it pays



The rotor: With tip speeds of up to 38 m/s even large
throughput rates and high viscosities can be handled in a very short time. The product retention period in the Shearpump is reduced to a minimum.

Right from the development stage we focus on the profitability of your production.

This is where the saving starts Compared with conventional dissolving processes in large tanks or biolers, using the Fristam Shearpump can cut your processing time by up to 90%. The Shearpump disintegrated agglomerates and lumps etc. with its high shear energy, and gives absolutely constant, repeatable results. This pump is also highly suitable for handling varying batch sizes. The forced flow of the products in the Shearpump ensures a continuously high standard of quality. Depending on the application, you can expect to use fewer raw materials because of the more effective breakdown of constitutents: When processing stabilizers, we noted a reduction in the raw materails requirement of 10%. Cleaning - the Shearpump is, like all Fristam pumps, fully CIP - capable. As a rule, you can carry out maintenance yourself since its construction is familiar due to its similarity to the centrifugal pumps. All in all we are talking here of a very short amortization period. We would be pleased to provide a test unit free of charge for trials in your production process.
