High Viscosity In-Line Mixers
High Viscosity In-Line Mixers
Silverson’s High Viscosity (HV) In-Line Mixers offer exceptional flow rates and the ability to process higher viscosity products.
This is achieved by a unique and innovative “pumping rotor” design which substantially increases the mixer’s capacity when compared to standard In-Line mixers, eliminating the need for an additional feed pump when processing higher viscosity products in the food, pharmaceutical, cosmetic and chemical industries.
Features:
- Ultra sanitary construction - based on the 3A Certified and EHEDG Certifiable UHS mixer range.
- Self-pumping
- Aeration free
- No bypassing
- Interchangeable workheads
- Vertical or self-draining tangential outlet
- Designed for Cleaning-In-Place
How It Works
Silverson UHS-HV In-Line mixers feature a special rotor design which provides increased capacity, and allows processing of higher viscosities. Operation is as follows:
The high-speed rotation of the specially designed pumping rotor within the precision-machined mixing workhead forces liquid and solid materials into the rotor/stator assembly.
Centrifugal force then drives the materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator.
This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator, then through the machine outlet and along the pipework. At the same time, fresh materials are continually drawn into the workhead, maintaining the mixing and pumping cycle.

Mixer Options
Verso-UHS-HV High Viscosity Mixer
As well as a full range of production machines, Silverson offers a laboratory scale model. The Silverson Verso-UHS-HV is designed for processing higher viscosity mixes than the standard Verso model. This model incorporates the same unique and innovative ‘pumping rotor’ design as the production scale UHS-HV In-Line mixer which substantially increases its self-pumping capacity and facilitates easy scale up to Silverson’s production scale UHS-HV Series In-Line mixers.
UHS-HV Small-Scale High Viscosity In-Line Mixer
The UHS-HV is the go-to solution for small-scale in-line manufacturing of higher viscosity products, matching the capabilities of production-scale Silverson HV In-Line mixers. It features a unique “pumping rotor” design that significantly increases self-pumping capacity, maintaining high flow rates of around 6,500 liters/hour even as viscosity rises. This innovative design often eliminates the need for an additional feed pump when processing higher viscosity products like creams, ointments, sauces, and slurries. With multiple motor options available, including high-speed variants up to 9,000 rpm for continuous recirculation of viscous products, as well as stainless steel and Flameproof models, this mixer offers exceptional versatility for a wide range of applications.
Workheads
A comprehensive range of workheads and screens is available for all Silverson high shear mixers. These easily interchangeable workheads offer great versatility by allowing any machine to be adapted to perform a wide range of mixing operations including emulsifying, homogenizing, disintegrating, dissolving, dispersing, blending, particle size reduction and de-agglomerating. Changing from one head or screen to another is quick and simple.
General Purpose Disintegrating Head
Used for a wide range of applications, this head will give the greatest throughput. Suitable for the blending of liquids of similar or greatly varying viscosities, its uses include the disintegration of solid and semi-solid materials.
Square Hole High Shear ScreenTM
The configuration and fine internal tolerances of this stator provide exceptionally high shear rates which are ideal for the rapid size reduction of soluble and insoluble granular solids. It is also suitable for the preparation of emulsions, gels and thickeners and fine collodial suspensions.
Slotted Disintegrating Head
For the disintegration of fibrous materials such as animal and vegetable tissue, as well as the disintegration and solubilization of “elastic” materials such as rubbers and polymers.
Emulsor Screens
These screens are suitable for liquid/liquid preparations and are especially useful for all emulsions. Emulsor screens are available in fine or medium perforations.
