Know-how
Why a used NETZSCH Vakumix or Vakumix plant from SEEFRIED?
Our company history is linked to homogenizing technology from Weyhe: Erwin Seefried, father of our founder André Seefried, has been named as inventor or co-inventor in numerous patents on agitators, scrapers and homogenizers since 1978 – from 1995 as founder and board member of Vakumix Rühr- und Homogenisiertechnik AG in Weyhe (our history). There is no connection to the trademark owners today; we use our knowledge of design and process engineering for inspection, overhaul, service and spare parts.
Design known
Homogenizer, agitator, scrapers and vacuum system: we know what matters with these plants – and only buy plants in very good condition.
Overhaul in our own workshop
New seals and wear parts, overhaul of the homogenizer and, on request, a new control system – in our workshop in Weyhe.
Compatible mechanical seals
For homogenizers from Vakumix and NETZSCH Vakumix, we supply compatible mechanical seals – not an original part, but an exact fit.
One point of contact
From selection through logistics and installation to commissioning, SAT and IQ/OQ support.

Checklist
What to look for when buying a used NETZSCH Vakumix or Vakumix plant?
What matters is the condition of the main components – rather than the year of construction. We check these points on every plant:
Homogenizer
- Rotor and stator, gap dimension
- Mechanical seal and bearings
- Speed range and drive
Agitator and scrapers
- Condition of the scraper blades
- Bearings and shaft sealing
- Concentricity and gap dimensions
Vessel
- Jacket: pressure and leak test
- Vacuum tightness
- Surfaces of product-contact parts
Controls and documentation
- Spare parts situation of the control system
- Wiring diagrams and drawings
- Declaration of conformity, material certificates
We check all of these points before purchase and again during the FAT in our workshop – with a report.
Compatible mechanical seals for Vakumix homogenizers
For homogenizers from Vakumix and NETZSCH Vakumix, we supply compatible mechanical seals – not an original part of the manufacturer. Plus maintenance, repair and modernisation of existing plants.
FAQ
Frequently asked questions about used NETZSCH Vakumix and Vakumix plants
Are you an authorised dealer or service partner of Vakumix or NETZSCH?
No. SEEFRIED Verfahrenstechnik GmbH is an independent company and neither a sales partner nor an authorised service partner of the manufacturer or trademark owner. We sell genuine used plants of this brand and provide overhaul, installation and service as our own services.
Is there a warranty on used Vakumix plants?
We sell the plants serviced and with a 12-month warranty provided by SEEFRIED, excluding wear parts. There is no manufacturer’s warranty on used plants.
How quickly can a used Vakumix plant be delivered?
Without modifications, 4 to 6 weeks are often possible; with overhaul and a new control system, usually under 6 months. New plants typically have a delivery time of 9 to 15 months until FAT.
How much does a used Vakumix homogenizing mixer cost?
We deliver most projects for less than 50 % of the cost of a comparable new plant – including installation, logistics, overhaul, FAT and SAT. The price depends on size, equipment, condition and scope of services; you will receive a specific quotation on request.
Can recipes be transferred from an existing plant?
As a rule, yes. With comparable agitator and homogenizer geometry, recipes can be transferred and scaled well. We check this case by case based on product, viscosity and process control.
Do you supply spare parts for Vakumix homogenizers?
For homogenizers from Vakumix and NETZSCH Vakumix, we supply compatible mechanical seals. These are not original parts of the manufacturer. We will be happy to clarify other spare and wear parts case by case.
I am looking for a specific NETZSCH Vakumix or Vakumix model – what can I do?
Create a search request. Our stock changes quickly; we will get in touch as soon as a suitable plant is available – including plants that have never gone into production.
Can I sell my Vakumix plant to you?
Please get in touch. We assess the condition with the eye of a plant engineer and, thanks to our market knowledge, often know suitable buyers.
