View of used machines for sludge dewatering and industrial production
Used filter presses
Used Filter Presses are ideal for liquid purification and solid separation – perfect for dewatering municipal and industrial sludge. Efficient, reliable, and in good condition.
Used Decanter Centrifuge
With a used decanter centrifuge, a used decanter solids are separated from liquids, or liquids with different densities are separated.
Used Industrial Mixers
Mixing with Used Industrial Mixers is a basic operation in the mechanical process engineering, where at least two substances are united to form a homogeneous mixture.
Used Pumps
If you are looking for used pumps, here you will find equipment designed to transport or pump liquids, including dense mixtures and pastes with high solid content and high viscosity.
Used Polymer Mixing Systems
Used polymer mixing systems are used for the production, processing and dosing of organic flocculants.
Used Screw Conveyor
A used screw conveyor transports bulk materials such as powder, granules, as well as pastes and also slurries. These are conveyed quickly and safely from point A to B in a trough or pipe channel by means of a rotating, helical screw conveyor.
Used generators and cogeneration plants (CHP)
A cogeneration (CHP) plant is a compact system that generates electricity and heat simultaneously from natural gas, biogas, and liquefied petroleum gas. A power generators are a system that produces electrical energy independently of the power grid.
Used Mills
With a Disintegrating Machine or Mill, bulky material is crushed to a fine or very fine-grained final product.
Diverse used Machines
Here you will find various second-hand machinery or used machines for different applications.
What Is a Used Machine
A used machine is a unit previously owned by at least one party. It may be in like-new condition with low operating hours or show signs of heavy use.
Many of these machines come from: Insolvency auctions, Plant closures, Production changes.
Even if they are partially dismantled, they can usually be made operational again with minimal effort – provided they were professionally disassembled.
Advantages of Buying Used Machinery
- Cost savings: Much more affordable than new equipment
- Immediate availability: No long waiting times
- Proven technology: Reliable and field-tested machines
- Ready to use: Operational immediately after proper installation
- Sustainability: Reusing machinery helps protect the environment
- Good value retention: Well-maintained machines often retain a better value than new goods
