High-Pressure Safety Filters
Description
Application
In the high-pressure circuits of hydraulic systems.
Performance features
Functional protection:
The high-pressure safety filter retains residues remaining in the
system due to installation or after repairs, and intake chops from
pumps (especially gear pumps). This prevents functional failures
or faults on downstream components, particularly control/
regulation or throttle valves.
Protection against wear:
For wear protection, a fine filter should be installed elsewhere in
the system.
Filter elements
Flow direction from outside to centre. The star-shaped pleating
of the filter material provides:
› large filter surfaces
› low pressure drop
› high dirt-holding capacities
› long service life
Materials
Housing: steel, zinc plated
Seals: NBR (FPM on request)
Filter media: stainless steel wire mesh (1.4301)

› at initial operation:
The recommended starting viscosity can be read from the
diagram D (pressure drop as a function of the kinematic
viscosity) as follows: find the 70 % ∆p of the cracking pressure
of the by-pass valve on the vertical axis. Draw a horizontal line
so that it intersects the ∆p curve at a point. Read this point on
the horizontal axis for the viscosity.

Quality Assurance
Quality management according to DIN EN ISO 9001
To ensure constant quality in production and operation, ARGO-HYTOS filter elements undergo strict controls and tests according to
the following ISO standards:
ISO 2941 Verification of collapse/burst pressure rating
ISO 2942 Verification of fabrication integrity (Bubble Point Test)
ISO 2943 Verification of material compatibility with fluids
ISO 3968 Evaluation of pressure drop versus flow characteristics
ISO 16889 Multi-Pass-Test (evaluation of filter fineness and dirt-holding capacity)
ISO 23181 Determination of resistance to flow fatigue using high viscosity fluid
Before release into the series production the filter casing is tested for fatigue strength in our pressure pulse test rig.
Various quality controls during the production process guarantee the leakfree function and solidity of our filters.
Illustrations may sometimes differ from the original. ARGO-HYTOS is not responsible for any unintentional mistake in this specification sheet.
