MP Filter Series LMP 112-123
The MP Filter Series LMP 112-123 is a versatile solution for low and medium pressure hydraulic systems, capable of handling flow rates up to 175 l/min and a maximum working pressure of 80 bar. Built with an aluminum head and a cataphoresis-coated steel housing, it offers high structural resistance. It is ideal for protecting sensitive components, use on mobile machinery, and coolant filtration in machine tools, ensuring maximum technical flexibility thanks to specific multiport configurations.
The MULTIPORT filter range, including the MP Filter Series LMP 112-123, represents versatile and high-performance solutions specifically developed for power transmission and the protection of particularly sensitive components within hydraulic systems operating at low and medium pressure. Among the main applications is also intensive filtration of coolant fluid directly inside machine tools. The filtration circuit is designed so that the flow passes through the filter element strictly from the outside toward the inside (OUT to IN direction). From an installation standpoint, these devices are directly connected to hydraulic system lines using specific standard fittings, featuring female threaded connections with diameters up to 1 inch, allowing management of a maximum return flow rate of 175 l/min.
The available configurations are commonly used along pressure lines, making them compatible with any low-pressure industrial equipment and a wide variety of mobile machinery. The inherently multiport nature and the numerous multifunction schemes available allow engineers to configure the system according to the specific application type. Filter clogging status can be continuously monitored through differential pressure indicators available in visual, electrical, or electronic versions (such as DLE, DTA, DVA, DVM models).
The completeness of the series is expressed through models structured for specific flow rates and connection schemes:
The mechanical strength of the component is ensured by the use of a head manufactured entirely in aluminum and an external housing made of reinforced steel with protective cataphoresis coating to maximize durability. Internal components related to the bypass valve are made of corrosion-resistant materials such as brass and aluminum. The allowable operating temperature range extends from -25°C to +110°C, supported by standard NBR seals (series A) and optional FPM versions (series V). Filters of the MULTIPORT series are designed exclusively for vertical installation.
Maximum operating performance allows continuous operation at pressures up to 8 MPa (80 bar). Strict testing confirms the exceptional reliability of the unit: test pressure performed at 12 MPa (120 bar), minimum burst pressure guaranteed at 24 MPa (240 bar), and outstanding fatigue resistance validated through pulsating pressure tests of 1,000,000 cycles. The bypass valve, where installed, features an opening pressure of 0.35 MPa (3.5 bar) with a tight tolerance of 10%. The filter element, sized to safely withstand a differential pressure of 20 bar, is available in inorganic microfibre versions (3 to 25 micron), wire mesh (25 to 90 micron), and resin-impregnated paper (10 or 25 micron).
