Suction filters up to 18.5 gpm, Tank top mounting, ES 074/ES 094
Application
To be installed in the suction line of the pumps of hydraulic systems resp. upstream of the charge pumps of hydrostatic drives.
Performance features
Protection against wear: By means of filter elements that, in full-flow
filtration, meet even the highest demands regarding cleanliness classes.
Protection against malfunction:
By means of full-flow filtration in the system return, the pumps, above all, are protected from dirt particles remaining in the system after assembly and repairs, which are generated by wear or enter the system from outside.
Special features
Filter element locking valve:
Foot valve:
Ensures that dirt accumulated in the filter element is removed along with the element and cannot return to the tank. When the screw-on cap is removed for maintenance, the foot valve closes automatically. This makes it possible to service the filter even if it is submerged below the oil level in a full tank.
Filter elements
Flow direction from center to outside.The star-shaped pleating of the filter
material results in:
- large filter surfaces
- low pressure drop
- high dirt-holding capacities
- long service life
In filters with a magnetic system, the ferromagnetic particles in the fluid first pass through a strong magnetic field and are separated.
Filter maintenance
By using a clogging indicator the correct moment for maintenance is stated and guarantees the optimum utilization of the filter life.
Materials
Screw-on cap: Filter head: Filter bowl: Seals: Filter media:
Polyester, GF reinforced
Aluminium alloy
Steel
NBR (Viton on request)
EXAPOR®-inorganic microfibre web
Paper-cellulose web, impregnated with resin
Accessories
Electrical and optical clogging indicators are available. Dimensions and technical data see catalog sheet 60.20.

Installed upstream of the pump or accessible from the outside in a particularly service-friendly configuration with a contamination indicator integrated in the suction line, suction filters protect the pump from large-particle contamination. A selection of elements adapted for use with the system protect installations and pumps in the range from 10 - 25 µm with our micro-quality products, or in the coarse particle range using easy-to-clean wire gauze.

Polytech's conventional vacuum filters provide reliable automatic filtration of water based machine tool coolants and are suitable for coarse or fine solid contaminants and coolant flow rates from 20 to over 600 gallons per minute. Conventional vacuum filters utilize the difference in pressure between the dirty coolant tank at atmospheric pressure and the lower pressure created by the centrifugal pump's suction characteristics to force coolant through a non-woven filter fabric. The filter pump supplies clean, filtered coolant to service. These systems use a robust sludge conveyor to transport spent filter media and solid contaminants from the filter while a clean coolant reservoir provides a means of supplying coolant while the filter media indexes so that there is no interruption in coolant supply to the machine tool(s).
Conventional vacuum filters can typically provide 5 PSI differential pressure across the filter media so that coolant flow rates and contaminant loading per square foot far exceeds the capability of gravity type filters. The non-pressurized design is more reliable than pressure filters that require complex media handling and sealing arrangements. The automatic, unattended operation is much easier and less labor intensive than cartridge or bag filters that require manual filter changes.

Vacuum Filtration
Vacuum suction is used to remove small contaminants from the spent coolant. A vacuum pump draws contaminated coolant through the filter screen. As the filter continues to run, it builds up a thick residue on its surface, known as filter cake, which traps even smaller contaminants and keeps them from migrating thorugh the filter screen.

High performance solid/liquid filter separation technology.
Drum filters are the most frequently used continuous rotary filters and are found in many different applications due to their simplicity and ease of operation.
Applications include solid/liquid separation processes in the chemical industry, plastics production, mineral refining, food processing industry and in the field of environmental protection.
Whether you require a vacuum, gas-tight or pressure filter, we have the right design to suit your specific requirements.
Our rotary drum filter offers a number of separation process advantages:
- Increased filtration capacity through improved hydraulic efficiency.
- Low operating costs through maintenance friendly design.
- Enhanced performance with gas-tight, pressurized configuration.
Main Applications:
Plastic intermediates, BPA, carbonates, cellulose, pigments, iron oxide, indigo, TiO2, red mud.

We manufacture vacuum filters which use consumable filter paper for filtration. These vacuum filters can effectively handle viscous fluids up to 40 Cst. They require lesser space as dirty fluid tank and filter are together. They can easily be designed to handle much larger flows & dirt quantities. They use pump suction vacuum for filtration in addition to gravity head available. Pressure drop used is about 4 m of fluid column. Hence gathers more dirt layer to perform much better than all types of gravity filters.

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)

Return Filters - lightline up to 18.5 gpm, Tank top mounting/In-line mounting, FR 043/FR 072
Application
In the return line circuits of hydraulic systems.
Performance features
Protection
against wear: By means of filter elements that, in full-flow filtration, meet even the highest demands regarding cleanliness classes.
Protection against
malfunction: By means of full-flow filtration in the system return,
the pumps are protected from dirt particles remaining in the system after assembly and repairs which are generated by wear or enter the system from outside.
Special features
Connection: Hose nipple
By-pass valve: The location close to the inlet port prevents dirt particles
retained by the filter element from entering into the clean
oil side. Removable bowl: In case of maintenance the filter bowl is removed
along with the filter element - so that dirt particles
are not flushed back into the tank. Oil separator: Prevents oil splashing through the breather on mobile
applications. Extension pipe: Easy and fast adaption to various lengths due to the
"do-it-yourself"-system.
Filter elements
Flow direction from outside to center. The star-shaped pleating of the filter
material results in:
- large filter surfaces
