MAHLE PI2130SMX3 Replacement Filter

Brief Introduction

Impurities in hydraulic oil will wear pumps, valves and cylinders and cause frequent equipment faults. Maintaining stable oil cleanliness is an 

effective way to cut operation costs. Original Mahle filters have stable performance, but they are expensive, with long delivery cycles and high

inventory costs.We supply interchangeable Mahle replacement filters. The PI2130SMX3 filter element matches OEM size and performance 1:1 for direct installation without modification.

Core Structural Advantages

3.1 Multi-Layer Composite Glass Fiber Media

Different from low-cost single-layer paper filters on market, our PI2130SMX3 adopts imported composite microglass fiber. Coarse inner fiber 

intercepts large metal debris, fine middle fiber captures tiny oxide particles, outer support layer prevents fiber shedding into oil. Deep pleating 

design increases effective filtration area by 30%, larger dirt holding capacity, service life extended by 40% under equal working conditions, less 

downtime from frequent filter change.

3.2 Thickened Integral Steel Support Frame

Thick galvanized steel mesh inside and outside, uniform dense holes with strong rigidity. No deformation or collapse under instantaneous 

system pressure peak, maintains stable filtration accuracy long-term. Cheap inferior filters use thin iron mesh, easy to rust and deform, leading 

to filter damage and secondary oil pollution quickly. Our galvanized steel frame resists medium corrosion over 2000 working hours.

3.3 Stable NBR Sealing Structure

End caps and NBR seals bonded by high-temperature vulcanization, no glue overflow or leakage gap. NBR fits most industrial mineral hydraulic

oil, hardening & cracking resistant under long-term temperature cycles. Full circumferential sealing after installation, stop unfiltered oil mixing 

into system, solve incomplete filtration caused by poor sealing of cheap alternatives.

3.4 Direct OEM Interchange Design

Fully restore original Mahle PI2130SMX3 dimensional tolerance and assembly interface. Customers can directly replace old original filter without

cutting, drilling or modifying filter housing accessories. Compatible with all standard Mahle PI series pressure filter housings, save maintenance 

labor and equipment transformation risks.

Main Application Industries & Matching Equipment

PI2130SMX3 3μm precision hydraulic filter is a general pressure line filter element, widely matched with medium and small hydraulic stations 

and lubrication systems in multiple industries:

1. Construction Machinery: Excavators, loaders, road rollers, concrete pump trucks, hydraulic oil fine filtration for engineering vehicle hydraulic 

stations

2. Mining Industry: Underground hydraulic support system, mineral processing equipment hydraulic station, stone cutting machinelubricationcircuit

3. Metallurgy & Steel: Rolling mill lubrication system, continuous casting machine hydraulic station, hydraulic equipment for heat treatment

furnace

4. Power Industry: Steam turbine lubrication system of thermal power plant, hydraulic control system of wind power equipment

5. Precision Machining: CNC machine hydraulic station, injection molding machine hydraulic system, die-casting equipment oil filtration

6. Petrochemical Industry: Pipeline valve hydraulic control unit, auxiliary hydraulic equipment of chemical reactor

7. Marine Machinery: Small ship deck hydraulic crane, auxiliary machinery lubrication filtration

8. Paper & Textile: Paper machine hydraulic power system, hydraulic circuit of textile printing equipment

Under harsh working conditions with heavy dust and 24-hour continuous operation, PI2130SMX3 replacement filter can maintain stable filtration

performance for a long time, effectively protect precision hydraulic parts and reduce equipment failure rate.

FAQ

Q1: Can PI2130SMX3 filter fully replace original Mahle element?

A: Yes. Overall dimensions, interface structure, sealing standard and pressure resistance are identical to OEM. No modification to filter housing or

pipeline is required, plug and play directly without leakage. It fits all filter housings designed for original PI2130SMX3.

Q2: What media is used for the filter element? How about its service life?

A: Multi-layer composite microglass fiber with Beta value ≥200. Its dirt holding capacity and service cycle are close to original Mahle filters, farbetter than cheap paper filters on market, cutting downtime caused by frequent replacement.

Q3: How to judge when the filter element needs to be replaced? Are there standard criteria?

A: Two core standards can be used: First, the filter pressure differential reaches the limit value specified by equipment manual. Second, oil 

sample test result fails ISO 4406 cleanliness standard. This filter has large dirt holding capacity with slow differential pressure rise. It can work 

withdifferential pressure transmitter to remind replacement timely, preventing hydraulic component abrasion from overdue filter service.

Q4: What hydraulic oil is compatible with this filter? Is it suitable for extreme temperature?

A: Equipped with NBR seal, compatible with general hydraulic oil, phosphate ester hydraulic oil, emulsion, water-glycol. Working temperature 

ranges from -30℃ to 100℃, stable for outdoor low-temperature construction and all-day high-temperature workshop operation.

Q5: Are inspection certificates available? What’s your after-sales policy?

A: Each batch comes with factory test reports including collapse pressure and filtration efficiency data, supporting supplier audit. 12-month

warrnty under normal operation. Free replacement for quality defects caused by production.
