Liquid Filtration and Separation Products

Pressure Filters

Designed for use as a full or partial flow filter and for low pressure up to 25/60 bar, medium pressure up to 210 bar and high pressure up to 450 bar, Filtration Group pressure filters are precisely tailored to the requirements of the application as line filters, flange filters and filters in sandwich plate design. Robust housings, flow optimized design and a comprehensive accessory program always offer the right solution for all market requirements.

Duplex Filters

Duplex filters allow a filter change during live operation and are thus suitable for use in motors and drives that have to reliably run continuously. Thanks to the compact design, duplex filters require little space and have a low flow resistance. Flow rate from 40 lpm to 8000 lpm with nominal pressure from 10 bar to 63 bar

Suction Filters

Whether installed in front of the pump or, for greater maintenance-friendliness, installed with maintenance indicator in the suction line for easy access from outside, they protect the pump from course impurities. With a wide range of system-compatible elements, the protection of systems and pumps in the fine range of 10 – 25 μm can be guaranteed with our MIC medias or in the coarse range with cleanable wire mesh. Flow rate range from 10 LPM to 630 LPM.

Return Filters

The combination of a suction filter and a return filter improves the energy balance compared to a separate system. With the integrated preloaded valve, the pressure in the return line is not reduced, but rather is directly used for suction.

Return Line Filters

The combination of a suction filter and a return line filter improves the energy balance compared to a separate system. With the integrated preloaded valve, the pressure in the return line is not reduced, but rather is directly used for suction.

Breathers

Corrosion and impact-resistance breather filters are used for impurity-free air supply of tanks. A large selection of system-compatible, changeable filter elements secures the required compatibility with the filter fineness of the hydraulic filters.

Filter Modules

For gear oil filtration (primary and bypass flow) and for lubrication systems in wind turbines, Filtration Group has developed an innovative, compact oil filter module that increases and sustains the efficiency and service life of the hydraulic and transmission units. The system consists of a filter block with electric motor, gear pump, filter housing with highly efficient 2-stage filter element, pressure relief valve, non-return valve and maintenance indicator. It is available in two versions with 110 l/min and 220 l/min volumetric flow. As a complete system in conjunction with an oil cooler, the oil filter module Pi 8300 ensures optimal filtration and cooling of wind power gearboxes and enables low-wear and maintenance-friendly operation.

Indicators

Indicators help optimize the monitoring and maintenance of filtration process.

Filter Carts

The high-performance devices for mobile and stationary bypass filtration in hydraulic and lubrication systems guarantee compliance with pre-defined purity classes when using suitable filter elements and can also be used with high-viscosity media. A robust, dirt-sensitive pump ensures a long service life and a wide application spectrum. When pumping into systems and containers, transferring tank contents or unloading system filters during commissioning or after repairs, mobile Filtration Group filter units are an attractive option because of their service-friendly handling and very high dirt collection capacity. Flow rate from 15 LPM to 100 LPM

Coalescers

These are specially designed for removing water from hydraulic systems. They run cost-effectively and easily without absorbents: Specially configured filter media collect the small water droplets suspended in the fluid and separate them.

Spin-on Cartridges

Spin-on cartridge filters help optimize the efficiency of the oil filtration process.

Filter Elements

The filter element performs the actual filtration and/or dewatering function in the housing. They consist of several pleated filtration and support layers. Their placement is a cylinder around or inside the stabilizing support tube.

Fuel Water Separators

The efficient fuel treatment system prevents concentrations of free water from rising above 70 ppm. It thus acts as an effective protection against the “diesel oil pest”. The single-stage system is used primarily in shipping, preventing engine damage and system failure. Because of its compact design, it takes up little space in the engine room of a ship. In the version as OFWA, the system is also used e.g. for dewatering hydraulic oils. Range for Fuel 670 LPH to 8000 LPH and Oil 5 LPH to 16 LPH

PTS/OTS

PTS/OTS is equipped with additional separator membranes in addition to the coalescer elements. These membranes prevent even the finest water droplets from escaping, which means that the fuel or oil is perfectly clean when it comes out. The system is well suited for protection of gas turbines in power plants and for fuel treatment on emergency power units. The PTS is individually configured for the particular requirements. Filtration Group delivers OTS standard sizes with a flow capacity from 300 to 2000 l/h. Other sizes are available upon request.

Crude Oil Dewatering

The system is the last word in raw oil deoiling. The system combines multi-phase separation, mechanical emulsion and foam breaker (MESB) and membrane filtration in one system and reduces the residual water content to less than 0.1%. The CWD / OTS is primarily used in the oil and gas industry and is individually adapted to the medium and the required purity level. The flow capacity reaches from 10 m3 to 100 m3 per hour. The system can optionally be run in fully automatic mode. Available from 10 m3/hr to 100 m3/hr

Metal Industry

In metal industries there is a need to clean metals parts from emulsified oils, lubricants and other impurities by passing them through metal elements washing machines. By using a Grundfos DynaFilter’s advanced membrane filtration technology to continuously treat the wash water, metal productions can achieve uniform washing quality while saving water, chemicals and energy because they avoid having to dump wash water often, raise temperature and add more soap

Uniform Wash Process Prevents Quality Issues and Reduces Operating Costs

Uniform wash process prevents quality issues. When consistency is key, the DynaFilter achieves uniform washing quality as it continuously treats water from the parts washer. You canfine-tune the DynaFilter for each application, ensuring you get the right results every time.

Reduced operating costs. As an in-line process that treats and reuses water and chemicals, theDynaFilter eliminates the need for batch tanks. You can expect reduced maintenance and cleaning costs as it reduces water dump frequency by up to 90%.
