MP Filtri LDP LDD Low & Medium Pressure Filters

MP Filtri LDP (in-line single) and LDD (duplex) filters have working pressures of up to 60 bar (870 psi), flow rates up to 330 litres/minute and threaded connections from 1 1/4” to 1 1/2” BSP/NPT/SAE. The LDD duplex filter has 1 1/2” SAE 3000 psi flanged connections.

Both LDP and LDD filters are available in sizes: 016 | 025 |040.

MP Filtri LDP filters have female threaded connections up to 1 1/2”, for a maximum return flow rate of 330 litres/minute.

Features of MP Filtri LDD filters:

• Integrated changeover function to allow the filter element to be replaced without system shut-down
• Female threaded connections up to 1 1/2” and flanged connections up to 1 1/2”, for a maximum flow rate of 330 litres/minute
• Balancing valve integrated in the changeover lever, to equalise the housing pressure before the switch
• Vent ports, to avoid air trapped into the filter going into the system
• Drain ports, to remove the uid from the housing prior the maintenance work
• Optional sampling ports, to get samples of uid or to connect additional instrument to the system

Features common to both MP Filtri LDP and LDD filters are:

• Filter element designed in accordance with DIN 24550 regulation
• Fine filtration rating
• Seals: standard NBR, series A | optional FPM, series V
• Water removal elements, to remove free water from the hydraulic fluid
• Bypass valve, to relieve excessive pressure drop across the filter media; opening pressure 350 kPa (3.5 bar) ±10%
• Temperature: from -25° C to +110° C
• Connections: inlet/outlet in-line
• Vertical mounting
• Visual, electrical and electronic differential clogging indicators

Filter housing materials:

• Head: aluminium
• Bowl: cataphoretic painted steel
• Bypass valve: AISI 304 – nylon

Pressures:

• Test pressure: 9 MPa (90 bar)
• Burst pressure: 21 MPa (210 bar)
• Pulse pressure fatigue test: 1,000,000 cycles with pressure from 0 to 6 MPa (60 bar)
