High pressure filters up to 6500 psi (450 bar) produce the lowest system contamination levels to assure clean fluid for sensitive high-pressure components and provide protection of downstream components in the event of catastrophic failures. Systems with high pressure flows typically need only be sized to match the output of the pump, where the return line may require a much larger filter for the higher flows. Schroeder's product range of high pressure housings includes top-ported, base-ported, servo protection (sandwich) filter housings, manifold mounted and manifold assembled, cartridge elements for use in manifold applications, hydrostatic (bi-directional) and high pressure water service filters.
Medium pressure filters up to 1500 psi (100 bar) are often considered when initial cost is a major concern. A special concern in applying return line filters is sizing for flow; large rod cylinders and other components can cause return line flows to be much greater than pump output. Return lines can have substantial pressure surges, which need to be taken into consideration when selecting filters and their locations. Schroeder's product range of medium pressure filter housings includes top-ported, base ported and medium pressure water service filters.
Low pressure filters up to 500 psi (35 bar) are primarily used for return line filtration. Our line of low pressure filter housings range from top-ported, tank-mounted, tank-integrated, special feature tank-mounted filters, severe duty tank-mounted, spin-on low pressure filters, and low pressure water service filters.
Our comprehensive range of hydraulic filter housings is continually tested using the latest ISO and NFPA test procedures in our engineering lab. Extensive testing is conducted to verify rated fatigue and burst pressures and to ensure compatibility with various hydraulic fluids, including the newest fire-resistant fluids. Schroeder filter housings are equipped with high-quality filter element materials to ensure high operating safety and long maintenance intervals.
Customers can also privately brand their filter housing for improvement of the product identification, and use protected construction like the Schroeder patented GeoSeal® technologies to ensure retention of spare parts in the aftermarket.
