The rotary vacuum drum filter (RVDF) is one of the oldest filters applied to industrial liquid filtration. A rotary drum filter resembles a large drum on its side. Half of the drum is submerged in the slurry, with the other half above it. The filter cloth winds around the drum and as the drum rotates, the slurry is sucked into the cloth. As the drum rotates out of the slurry, the cake is dried. This drying is caused by the vacuum continuously being drawn through the cake in the exposed section of the drum. At the end of the rotation cycle, at approximately a three o'clock position, the filter cake will be discharged and the process repeats itself. The filters may incorporate a drum cloth that is caulked onto the drum itself, or they may utilize an endless belt which tracks off and discharges away from the drum.
Typical Applications:
- Kaolin clay
- Titanium dioxide
- Alumina (red mud)
- Pharmaceuticals
- Chemical Processing
- Food processing (starches)

The Spring is a self-cleaning drum filter complete with a fixed filtering net, for the elimination of magnetic and amagnetic particles from both neat and soluble coolant liquids.
The Spring Range comprises of 6 models capable of purifying from 20 – 300 l/min of neat oil and from 50 – 90 l/min of emulsions.
The filtration efficiency of the drum can be customised according to the customers requirements.
The self-cleaning filters in the Spring Range can be used together with a wide variety of machine tools such as machining centres, deep hole drilling, transfer, grinding and milling machines, machining with special tools requiring high-pressure coolant. The Spring range is particularly ideal for work that involves the removal of metal fines produced using machine tools, abrasives and washing. It is therefore flexible and meets a wide variety of the demands posed by both the engineering and the automotive industries.

Considerable quantities of metal chips are produced in the automated factories of transformation of
metals. The productivity of the factory can be improved in an important way thanks to a continuous system of removal and
of treatment of the chips, because the operator does not waste any more his time to get rid of the chips but it produces.
An economic system of removal of the chips and treatment of cutting fluids requires however
solutions to measure.
The chips are collected and convoyed out of the production zone thanks to especially studied conveyers.
The long chips or in ball are reduced by crushing in a regular flow of short pieces. Wet chips
are dried and cutting fluids are recycled and cleaned. The process must be continuous and asks only one work
minimum handbook.
The effective and economic solution for the treatment of the chips varies according to the company, according to the provision
workshop, volume and characteristics of the chips.
Sermeto & Arboga-Darenth have the experiment and know-how to bring the most economic solution,
adapted to your Company, either thanks to our standard equipment, or thanks to our integrated systems of treatment of the chips.

Polytech magnetic separators have been designed to remove ferrous and non-ferrous solid contaminants from coolants and oils. Magnetic separators can substantially reduce filter cartridge consumption and element changes when used in grinding, honing and lapping operations where filter cartridges are used. They can reduce the concentration of small fines left in the coolant by chip conveyors in broaching, milling and drilling operations that can settle in tanks and reduce tool life.
The magnetic drum is made up of alternating permanent magnets and steel discs. The magnetic field is extended by the magnetized steel discs to maximize effectiveness without resorting to more costly high strength or rare earth magnets. A comb type scraper and adjustable discharge chute optimizes sludge removal.

Degreasing liquid, filter concentrate, coolants, minerals
The wet drum separator NTS is used to remove very fine magnetisable components from low concentration, low-viscosity liquids. The NTS is intended for use in the metal processing industry and for the treatment of preconcentrates extracted from the STEINERT high gradient magnetic filter HGF.
Around 90 % of the grain sizes ranging from 1 µm to 1000 µm can be separated as sludge. Features such as stainless steel housing and powerful neodymium iron bore magnets are standard.
General Principe
The liquid flows through a semicircular separating chamber beneath a stainless steel drum to which the magnetisable particles are attracted. The strong, high-gradient magnetic field is created by a cylinder consisting of permanent magnetic discs positioned within the drum. These special permanent magnets generate particularly high field gradients which are necessary for successful separation, as is the need with all magnetic separators.
