Filters

Suction line

MP Filtri suction filters are used as safety filters to protect pumps from gross contamination which can cause them to stick.

They are available in 3 styles:

• Suction Strainer
• FAS external filters, for mounting above the oil level
• SF2 external filters, for mounting semi-immersed under the oil level

SF2 semi-immersed filters, which shut off oil flow while the filter element is being replaced, replace the butterfly valves usually used for servicing hydraulic pumps.

Return line

MP Filtri return filters are used as process and safety filters to protect pumps and hydraulic circuits from contamination as per ISO 4406.

They are available in 4 styles:

• MPF semi-immersed filters for mounting to the oil tank with external/internal filter element.
• MPT semi-immersed filters for mounting to the oil tank with external/internal filter element.
• MPH/MPI semi-immersed filters for mounting to the oil tank with external/internal filter element.
• FRI semi-immersed filters for mounting to the oil tank or in-line, available in the single or duplex versions with external/internal filter element.

Pressure Line

MP Filtri high pressure filters are used as process filters to protect individual valves or the entire hydraulic circuit from contamination as per ISO 4406.  

11 versions are available with operating pressures ranging from 110 bar to 560 bar.  A range of products are available to resolve all filter mounting problems, in the following configurations:

• In-line, with threaded and flange mounts.
• Manifold top mounting.
• Manifold side mounting.
• Manifold mounting, to DIN 24340 CETOP R 35 H.
• Manifold threaded/flange mounting in the top extraction filter cartridge version.
• Duplex versions for continuous operation requirements.

The range includes a complete set of valves:

• Bypass valve.
• Check valve.
• Bypass + check valve.
• Reverse-flow valve.
• Reverse-flow + bypass valve.

Spin-On filters

Spin-On filters are used as process and safety filters to protect individual pumps, valves or the entire hydraulic circuit from contamination as per ISO 4406.

Operating pressure 12 bar.

In-line Spin-On filters can be used for the following purposes:

• Suction filters
• On the return circuit, for mounting on the line or on the tank cover
• In-line for low pressure

Spin-On filters are available in 4 configurations:

• Single cartridge in-line
• In-line with two parallel cartridges on the same axis
• In-line with two parallel cartridges mounted side by side
• With single cartridge flange for installation to the tank cover

All versions may be equipped with visual and/or electrical blockage indicators

Fillers & breathers

MP Filtri tank filler and breather filters are used for the filtration of the incoming air to the tanks of hydraulic systems and for filling the oil on the hydraulic tank.  Available in versions with: threaded connection, welded and flange mounting with screws.

Visual Level gauges

MP Filtri visual level indicators of fluid for hydraulic tank.

Low level switches

MP Filtri electrical level switches/indicators of fluid for hydraulic tank. 

Particle Counters

It is estimated that 70-90% of all component failures, and 45% of bearing failures in a hydraulic system, are due to contamination of the hydraulic fluid.

If left unchecked, it could cause damage to expensive components, leading to costly downtime for your system.  MP Filtri oil-sampling, particle analysis, and in line contamination monitoring are some of the many ways you can check the health of the fluid in your system, and catch potential contamination issues before they cause damage.  Please review the MP Filtri Fluid Condition Handbook for more information on how to keep your system in top condition.

Flushing Rigs

Particle contamination is the biggest risk to your hydraulic system.  Flushing is used to clean pipes and hoses in a system by pumping oil through them at flow rates high enough to cause turbulent flow.  The turbulence helps dislodge any dirt particles that may be present in the lines. 

MP Filtri rigs can also be used as off-line filtration systems, whereby the system is completely filtered when not in use or at periodic intervals as part of a standard maintenance schedule.  These rigs can be supplied with in line contamination monitors, allowing the operator to achieve and maintain a desired cleanliness level for the system.
