3. Description:
The pressure filters of the series EHP are suitable for a working pressure up to 11600 respectively 20300 PSI.
The pressure peaks are absorbed by a sufficient margin of safety. The EHP-filter is in-line mounted
The filter element consists of star-shaped, pleated filter material which is supported on the inside by a perforated core tube and is
bonded to the end caps with a high-quality adhesive. The flow direction is from outside to inside. Filter elements are available down
to a filter fineness of 1µm.
Internormen Product Line filter elements are known as elements with a high intrinsic stability and an excellent filtration
capability, a high dirt-retaining capacity and a long service life.
Internormen Product Line filter are suitable for all petroleum based fluids, HW-emulsions, most synthetic hydraulic fluids and
lubrication oils.
Internormen Product Line filter elements are available up to a pressure difference resistance of p 2320 PSI and a rupture strength
of p 3625 PSI.
The internal valves are integrated into the centering pivot for the filter element.
After reaching the opening pressure the by-pass valve causes that an unfiltered partial flow passes the filter.
