About MP Filtri
MP Filtri Hydraulic Filtration & Fluid Management
MP Filtri, a worldwide leader in hydraulic filtration equipment, specializes in designing and manufacturing advanced filtration systems for hydraulic fluid conditioning, contamination control, and system maintenance across industrial, mobile, agricultural, construction, mining, and material-handling applications. With headquarters in Italy and distribution across 100+ countries, MP Filtri delivers mission-critical filtration where fluid cleanliness directly impacts machinery uptime and component longevity.
MP Filtri's comprehensive product portfolio includes high-pressure filters (rated 20-560 bar), low and medium-pressure return-line systems, spin-on and stainless-steel cartridge filters, suction strainers, tank-top accessories, mobile filtration carts for pre-filtering and fluid conditioning, and advanced contamination monitoring systems. Filter elements are engineered for flow rates spanning 30 L/min (compact systems) to 3,000 L/min (high-volume industrial circuits and hydraulic power stations).
The MPS spin-on filter series offers quick-change cartridge replacement without system depressurization, rated up to 250 bar for suction, return, and pilot-pressure applications. The MPH spin-on line extends pressure rating to 560 bar for high-pressure main-line filtration in injection molding, press equipment, and closed-loop industrial systems. Mobile filtration units employ two-stage cascade design with 10µm and 3µm elements, user-portable construction, and internal bypass valves protecting downstream components during cold-start fluid transfer and conditioning cycles.
All MP Filtri elements meet ISO 4572 and SAE J1858 cleanliness standards, with element integrity verified by collapse-resistance testing (20+ differential pressure margin) and multi-pass efficiency ratings. Contamination monitoring sensors (portable particle counters, inline monitors) integrate with condition-based maintenance programs, enabling predictive fluid replacement and reducing unplanned downtime in critical hydraulic systems.
ChatMRO's AI instantly matches your hydraulic system's flow demand, operating pressure, installation location (main-line/return/suction), fluid type, and cleanliness target to the right MP Filtri filter element or mobile unit. No pressure-drop calculation needed—describe your system and get instant filtration recommendations with element specifications and cross-reference data.

Frequently asked questions
What's the difference between MP Filtri MPS and MPH spin-on filters and which should I specify?
MPS spin-on filters are rated up to 250 bar and suitable for return-line, suction, and pilot-pressure applications in mobile equipment (loaders, excavators) and mid-range industrial systems. MPH spin-on filters handle main-line pressures up to 560 bar and are required for high-pressure injection molding machines, press systems, and closed-loop servo-hydraulic circuits where fluid cleanliness is critical to valve/pump longevity. MPH elements are premium-priced but prevent catastrophic component failure in high-pressure systems.
How do I calculate the correct filter flow rating for my hydraulic system to prevent pressure drops?
Flow rating should accommodate peak system demand with a safety margin: multiply your maximum pump output (gpm or L/min) by 1.15-1.25 to account for cooler bypass and measurement uncertainty. A system with 50 gpm peak flow requires a filter rated minimum 60-65 gpm. Undersizing causes excessive differential pressure (pressure drop), heating fluid, damaging pump seals, and triggering bypass valves; oversizing increases initial cost but ensures stable system pressure and element longevity.
When should I use a mobile MP Filtri filtration unit instead of just replacing fluid in-place?
Mobile units (typically 10µm then 3µm cascade elements) are essential for systems contaminated above target cleanliness targets (ISO 19/17/14 or worse) due to internal leakage, seal wear, water ingress, or oxidized fluid. On-site circulation through the mobile unit brings fluid back to ISO 17/15/12 in 4-8 hours without system shutdown, extending component life and avoiding expensive emergency repairs. Cost is justified on systems valued over $50,000 or when downtime cost exceeds the mobile unit rental/purchase.
What pressure drop should I expect across a clean versus loaded MP Filtri filter element?
Across a clean, properly-sized filter element, differential pressure is typically 0.5-1.5 bar (light pressure systems) to 2-4 bar (high-pressure systems). As contamination accumulates, pressure drop rises linearly; bypass valve opening is typically set at 3.5-4.5 bar differential to signal element replacement need. Exceeding bypass setpoint indicates element saturation; continuing operation risks contamination bypass and rapid component wear, so element replacement cannot be delayed when bypass pressure is reached.
Are MP Filtri elements compatible with biodegradable and synthetic hydraulic fluids used in environmentally-sensitive applications?
Yes, MP Filtri manufactures elements specifically certified for ester-based, bio-hydraulic (rapeseed oil), and PAO synthetic fluids used in agricultural, mining, and water-table-sensitive operations. Element material (glass microfiber, synthetic media) and separator design differ from mineral-oil-optimized elements to prevent swelling, delamination, and flow bypass. Always confirm element compatibility rating with the fluid type before installation; using mineral-optimized elements with synthetics risks premature failure and system contamination.
