LMP 400 - 430

Product catalog summary

Specifications:
The document outlines the specifications for the LMP 400 and 401 filter series. The maximum flow rate is 740 l/min, and the maximum pressure is 60 bar. The filter housing is made of anodised aluminium, with a steel bypass valve. The working pressure varies depending on the length of the filter, with lengths 2-4 having a working pressure of 60 bar and lengths 5-6 having a working pressure of 50 bar. The temperature range for operation is from -25°C to +110°C.

Procedures:
The document details the pressure testing procedures, including a test pressure of 90 bar for lengths 2-4 and 75 bar for lengths 5-6. Burst pressure tests are conducted at 180 bar and 150 bar, respectively. A pulsed pressure fatigue test is conducted for 1,000,000 cycles.

Norms and Compatibility:
The filters are compatible with mineral oils, synthetic fluids, aqueous emulsions, and water and glycol. The seals are available in NBR and FPM, with specific compatibility for different fluid types.

Recommendations:
The document recommends maximum flow rates based on oil velocity, with a maximum of 2.5 m/sec for pressurised lubrication and 5 m/sec for return or in-line filters. For off-line filters, the pressure drop should be between 0.2 and 0.3 bar. Option P02 is suggested for reduced flow rates below 100/150 l/min.

Technical Data:
The document includes detailed technical data on filter dimensions, connections, and spare parts. It provides information on the differential pressure indicators and ordering information for the LMP 400-431 series.

Option P02 “Internal tube for reduced flow rate” is recommended for flow rate values below 100/150 I/min. The use of option P02 makes it easier to fill the housing with the operating fluid. Recommended maximum flow rate Recommended maximum flow rate for filters installed on lubrication lines, return or in-line filters is defined by the maximum oil velocity in the connections. For filters mounted on Off-Line lines the maximum recommended flow rate is defined by the pressure drop of the filter element. Filter for pressurised lubrication, max. oil velocity 2.5 m/sec. Return or in-line filter, max...
