Ultramix Mixers
Ultramix Mixers
The Silverson Ultramix is a versatile industrial mixer designed to excel in applications that push the limits of conventional agitators and stirrers, without the intense high shear of a rotor/stator mixer. Here’s how the Ultramix tackles your toughest mixing tasks:
Effortless Powder Incorporation
- Effective for Challenging Powders: The Ultramix’s vigorous action effectively handles fine, cohesive powders like gums and thickeners, preventing clumps and agglomerates from forming to ensure even distribution throughout your mix. It also excels at incorporating difficult powders that tend to float or “raft,” including light-density powders that traditional agitators struggle to overcome due to buoyancy.
Narrow Profile, Robust Mixing Performance
- Small Diameter Mixing Head: The narrow profile of the Ultramix is particularly well-suited for use in containers with small openings, such as IBCs (tote bins).
- Durable, Low-Maintenance Design: The simple yet robust design of the single-piece mixing head means there are no wearing parts or bushings, making it a more durable, low-maintenance solution compared to folding impeller mixers which utilise hinges, pivot points or other folding mechanisms that are more prone to wear and failure over time.
Vigorous In-Tank Movement
- The Ultramix creates a powerful axial flow pattern throughout the vessel, ensuring all materials are constantly engaged in the mixing process. Agitators and impellers might not achieve the same level of movement, especially in high viscosity mixes, leaving you with pockets of unmixed material.
Additional Benefits:
- Ultra-Hygienic Design: Single-shaft, single-piece mixing head simplifies cleaning and sanitisation, meeting 3A TPV (Third Party Verification), USDA, and cGMP requirements.
- Designed for Clean-in-Place (CIP), Sterilise-in-Place (SIP) Optional: Ensures a hygienic mixing environment for pharmaceutical and food applications, minimising downtime and simplifying maintenance.
- Versatile Performance: Suitable for a wide range of applications, from aggressive chemical mixing to the most demanding sanitary needs.
How It Works
As the mixer rotates at high speed, the grooves on the outside of the dynamic mixing head project the surrounding product outwards with great force, creating an area of low pressure around the trailing edge of each groove.
This draws product from within the mixing head, through the radial slots to the outside, subjecting the material to a shearing action. The grooves in the head drive the product outwards into the body of the mix at high velocity.
As material is drawn out of the slots, fresh material is sucked in through the holes in the top and bottom of the mixing head; this material is then drawn out through the slots and projected back into the mix. The pumping effect of the grooves and the shear action of the radial slots ensures rapid mixing, and develops a vigorous axial flow pattern throughout the vessel.

Mixer Options
Ultramix
Ideal for rapidly wetting out powders including gums and thickeners, the Ultramix is also ideal for use in vessels with narrow openings. The vigorous mixing action is capable of moving the entire contents of vessels even in difficult shaped containers. For this reason the Ultramix offers considerable advantages for customers using IBCs (tote bins).
Laboratory Scale Unit
The Ultramix laboratory assembly is designed for use with the Silverson L5 Series Laboratory mixers, allowing the user to replicate the mixing characteristics of production scale Ultramix units in the laboratory.
The Ultramix is ideal for use in narrow necked containers, and provides excellent product circulation, allowing the laboratory model to mix volumes of up to 12 litres (depending on product viscosity).
IBC Mixing
The Ultramix is ideal for mixing in problematic containers such as IBCs and Tote Bins - the highly efficient in-tank movement provided by the small diameter workhead overcomes the problems often encountered with difficult vessel geometry.
Ultramix Bottom Entry
The Ultramix can be supplied as a Bottom Entry unit, ideal for ultra-hygienic applications in the pharmaceutical and food industries.
