Mobile Hydraulic Filtration for Hydraulic Systems

Clean hydraulic oil is essential for the reliable operation of hydraulic pumps, valves, motors, cylinders, and other precision components.

Even very small particles can contribute to component wear and hydraulic system failures. For this reason, hydraulic oil filtration and contamination control are important parts of preventive maintenance and hydraulic system commissioning.

The Seide RK91 Pro allows hydraulic and lubrication systems to be filled, cleaned, and filtered using a compact mobile filtration unit. Its mobile construction makes it easy to move between machines, service areas, and hydraulic systems.

The compact design is particularly useful where available working space is limited.

Multi-Stage Hydraulic Oil Filtration

The RK91 Pro can be configured with different filter stages according to the required filtration level.

3-Stage Filtration

60 micron → 25 micron → 10 micron

This configuration provides progressive filtration by removing larger particles first and then continuing with finer filtration stages.

2-Stage Filtration

25 micron → 10 micron

The two-stage configuration provides a compact solution for applications where an initial coarse filtration stage is not required.

1-Stage Filtration

10 micron

The single-filter configuration is suitable for applications requiring a simple filtration solution.

Optional 5 Micron Filtration

A 5 micron filter element can be selected as the final filtration stage when finer hydraulic oil filtration is required.

The appropriate filtration level should be selected according to the hydraulic system, oil condition, installed components, and required cleanliness level.

Hydraulic Oil Filtration and Contamination Control

Hydraulic fluid contamination can have a significant effect on the performance and service life of hydraulic components.

Contaminated hydraulic oil may contribute to:

Hydraulic valve malfunction
Pump and motor wear
Increased component wear
Reduced hydraulic system reliability
Unexpected machine downtime
Increased maintenance requirements
Premature replacement of hydraulic components

The RK91 Pro provides a practical method for circulating hydraulic oil through dedicated filtration elements and returning the cleaned fluid to the system or reservoir.

Regular offline filtration can complement the machine's existing hydraulic filtration system and support a preventive maintenance program.

Hydraulic System Flushing

In addition to hydraulic oil filtration, the Seide RK91 Pro can be used for hydraulic system flushing applications.

Hydraulic flushing is particularly important when commissioning a new hydraulic system or after maintenance, repair, hose replacement, or hydraulic piping installation.

During installation and maintenance, contaminants such as:

Welding residues
Pipe debris
Assembly particles
Dust
Seal particles
Manufacturing residues

may enter hydraulic circuits.

The flushing process circulates hydraulic oil through the hydraulic lines to remove particulate contamination before the system is returned to normal operation.

The required flushing procedure and target cleanliness level should be determined according to the hydraulic circuit design and the requirements of the hydraulic components.

Hydraulic Oil Cleanliness Monitoring

For applications where oil cleanliness needs to be measured, the RK91 Pro can be equipped with an electronic particle counting and contamination monitoring system.

The particle monitor allows contamination levels in hydraulic oil to be evaluated by measuring particles within different size ranges.

Measurements can be used to determine the cleanliness condition of the hydraulic fluid according to recognized cleanliness classifications, including ISO and NAS standards.

Particle measurement provides objective data before and after filtration, making it possible to monitor the effectiveness of the cleaning process.

This is especially useful for:

Hydraulic system commissioning
Preventive maintenance
Hydraulic service operations
Critical hydraulic systems
Servo and proportional valve applications
Industrial hydraulic equipment

Minimes Connection for Direct Measurement

The RK91 Pro supports direct connection to hydraulic lines through Minimes test points.

This allows the particle monitoring equipment to be connected directly to the hydraulic circuit for contamination measurements.

The measurement system can provide a written report showing particle quantities across different particle-size ranges, from approximately 2 to 100 microns, together with the corresponding ISO and NAS cleanliness classifications.

Compact and Ergonomic Design

The Seide RK91 Pro was designed with mobility and operator ergonomics in mind.

Its compact construction makes it easier to transport and operate in hydraulic service environments where working space can be limited.

The suction and return hoses are secured to the frame using dedicated supports, while the electrical cable and additional service equipment can be conveniently arranged on the unit.

The optimized weight distribution also makes the machine easier to tilt and move during transportation.

The foldable handle and compact overall dimensions make the unit practical for transportation and storage.

Hydraulic Filtration Machine Configurations

The RK91 series is available with different filtration configurations:

RK 91 – 3 Filter Configuration

60 micron + 25 micron + 10 micron

Designed for progressive multi-stage hydraulic oil filtration.

RK 91.2 – 2 Filter Configuration

25 micron + 10 micron

A compact two-stage filtration configuration.

RK 91.1 – 1 Filter Configuration

10 micron

A simple single-stage hydraulic oil filtration solution.

The filtration rating of the filter elements can also be changed according to application requirements.

Economic Hydraulic Oil Filtration

Effective hydraulic oil filtration can help reduce contamination-related maintenance costs and protect valuable hydraulic components.

By removing particulate contamination from hydraulic oil, the RK91 Pro can support:

Longer hydraulic component service life
Reduced wear
Reduced maintenance requirements
Reduced filter replacement frequency
Improved hydraulic system reliability
Lower risk of contamination-related downtime

The actual service life of hydraulic oil and components depends on operating conditions, contamination levels, oil condition, filtration performance, and the recommendations of the equipment manufacturer.

Filter Element Replacement

Regular inspection and timely replacement of filter elements are important for maintaining the performance of a hydraulic filtration machine.

Filter element replacement frequency depends on factors such as:

Hydraulic oil contamination level
Oil viscosity
Operating conditions
Filtration frequency
System cleanliness
Filter element capacity

A highly contaminated hydraulic system may require more frequent filter element replacement during the initial cleaning process.

Once the desired cleanliness level has been achieved, filter replacement intervals can be established based on operating conditions and maintenance data.

Hydraulic Filtration vs. Hydraulic Oil Replacement

Replacing hydraulic oil is not always necessary when the primary problem is particulate contamination.

A mobile hydraulic filtration machine allows contaminated hydraulic oil to be circulated through filtration elements and returned to the reservoir or hydraulic system.

This can be an efficient solution for maintaining hydraulic oil cleanliness and reducing unnecessary oil replacement.

However, particulate filtration does not correct every type of fluid degradation. If the oil has experienced oxidation, chemical degradation, incorrect viscosity, severe water contamination, or other fluid-quality problems, appropriate oil analysis should be performed before selecting a filtration or oil replacement strategy.

A mobile hydraulic filtration system provides flexibility because the same machine can be transported between different hydraulic systems.

The Seide RK91 Pro combines:

Mobility
Compact construction
Multi-stage filtration
Hydraulic flushing capability
Optional particle monitoring
