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


  • 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)
