The HF4P1SD6UHB3C03 accessory belongs to the Vickers Hydraulic Accessories series and is manufactured by Vickers for fluid conditioning in automated hydraulic systems. It handles a rated flow of 189 L/min (50 US gpm) so circuits with moderate to high demand remain supplied, and it operates safely at 345 bar (5000 psi) while resisting cyclic loads up to a fatigue pressure of 240 bar (3500 psi). A Beta ratio of 1000 specifies high filtration efficiency for contaminant control, and a bypass valve set to open at 6 bar (90 psi) prevents excessive differential pressure across the element. The clogging indicator is calibrated to signal at 4.9 bar (70 psi), giving maintenance staff time to replace the element before bypass occurs. Acceptable service temperatures range from –26 °C to 121 °C, allowing use in both cold starts and elevated-temperature industrial environments.
The assembly uses a ductile iron head to support hydraulic connections, a matching ductile iron lid to secure internal components, and a carbon steel bowl that withstands line pressure while containing the filter media. Buna-N seals isolate the working fluid and are compatible with common petroleum-based oils. The element collapse rating of 10 bar (150 psi) guards against media failure during cold-oil conditions or downstream blockage events. A Hirschmann electrical indicator transmits the clog signal for remote status monitoring. Connection to the circuit is made through a 1.875-12 UN SAE-24 threaded port, ensuring compatibility with standard high-pressure fittings. The unit’s dry weight is 28.8 kg (63.4 lb), which should be considered when selecting mounting hardware and support brackets.
