MP Filter FHB Series
The MP Filter FHB Series is the ideal technical solution for protecting sensitive components in high-pressure hydraulic systems, specifically designed for mobile machinery and industrial equipment. It ensures excellent performance with a maximum working pressure of 320 bar (32 MPa) and flow rates up to 485 l/min. Equipped with manifold connection and designed for vertical mounting, it guarantees optimal fluid cleanliness within the hydraulic circuit.
The high-pressure filters of the FHB series, developed by MP Filtri, are designed to ensure rigorous protection of sensitive components in high-pressure hydraulic systems. Their main application is found in delivery lines of mobile machinery and various types of industrial equipment. These filters are connected directly to the manifold block side through a dedicated flanged interface, supporting connections up to 30 mm in diameter. The design provides exclusively for vertical mounting.
The entire range is capable of operating with a maximum working pressure of up to 32 MPa (320 bar) and handling maximum flow rates up to 485 l/min. The materials used in construction reflect the need to operate in critical environments: the head is made of phosphated cast iron, while the housing is made of phosphated steel.
The level of safety and reliability is certified by rigorous tests:
The system offers maximum versatility thanks to several internal valve configuration options. The bypass and check valves are made of steel. The bypass valve has a standard opening pressure of 0.6 MPa (6 bar) with a tolerance of ±10%. The check valve is intended to protect the system from possible reverse flows.
The filter elements are designed to adapt to the presence or absence of the valves, with flow direction from outside to inside (From OUT to IN):
Available filter media include inorganic microfiberglass (filtration grades 3 µm, 6 µm, 10 µm, 16 µm, 25 µm) and wire mesh (25 µm).
The family is available in four main sizes: FHB 050, FHB 065, FHB 135, and FHB 320, each available in different lengths (from 1 to 5, depending on the model). The sealing system provides for the use of standard NBR seals (series A) or, on request, FPM seals (series V). To monitor operating efficiency, visual (e.g. DVA, DVM), electrical (e.g. DEA, DEM, DEU), or electronic (DTA) differential clogging indicators can be installed.
