MP Filter Series LPH 630
The MP Filter Series LPH 630 is a high-capacity solution developed for low and medium pressure filtration in industrial environments. It ensures a maximum working pressure of 10 bar and handles flow rates up to 1600 l/min. Ideal for lubrication systems, it features 2 1/2″ flanged connections with versatile orientation. It includes a large filtration surface, water-removal elements, and an optional magnetic filter designed to capture ferrous particles.
The MP Filter Series LPH 630 range represents a high-capacity solution specifically designed to operate within low and medium pressure systems. Featuring a large filtration surface area, this device is particularly suitable for heavy-duty industrial applications and for off-line reservoir filtration in lubrication systems. Installation for units in this series is strictly vertical, while the flow direction through the filter element proceeds from outside to inside, commonly referred to as OUT to IN.
In terms of performance, the filter operates with a maximum working pressure of 1 MPa (10 bar) and ensures a maximum flow rate of 1600 l/min. Fluid inlet and outlet connections are provided through 2 1/2″ flanged ports, designed to offer versatile orientation according to the specific layout requirements of the hydraulic system. To protect the filter media from excessive pressure drops, the device integrates a bypass valve. This valve can be configured with an opening pressure of 0.175 MPa (1.75 bar) or 0.25 MPa (2.5 bar), both with a tolerance margin of ±10%. Reliability tests confirm high performance: it withstands a test pressure of 1.5 MPa (15 bar), features a minimum burst pressure of 3 MPa (30 bar), and has successfully passed pulsating pressure fatigue tests up to 1,000,000 cycles. The permitted operating temperature range is from -25°C to +110°C.
The materials used for the housing are selected to ensure mechanical strength and long service life. The head and cover are manufactured from anodized aluminum, while the bowl and bypass valve are made of phosphated steel. In terms of sealing, the standard model uses NBR seals (series A), with FPM seals (series V) available as an option. For condition monitoring, the system supports the installation of visual, electrical, or electronic differential clogging indicators. The total weight for the length 7 version is approximately 1.50 kg, occupying an internal volume of 0.60 dm³.
The versatility of the filter is further ensured by the wide range of compatible filter elements, all designed with a collapse pressure (Δp) resistance of 10 bar. Available filter media options include inorganic microfiber (A), water-absorbing microfiber (WA), wire mesh (M), and resin-impregnated paper (P). Filtration ratings range from very fine values such as 3 µm up to 90 µm, enabling the exact cleanliness level required by the hydraulic system. Additionally, the integration of a magnetic filter enables effective retention of ferrous particles, further protecting critical circuit components.
