1 High Pressure Filters Worldline HD HD 7 In-line mounting Operating pressure up to bar Nominal flow rate up to 9 l/min Description Application In the high pressure circuits of hydraulic systems. Performance features Protection against wear: By means of filter elements that, in full-flow filtration, meet even the highest demands regarding cleanliness classes. Protection against malfunction: Through installation near to the control valves or other expensive components. The specific determined flow rate guarantees a closed by-pass valve even at ν mm /s (cold start condition). Filter elements Flow direction from outside to centre. The star-shaped pleating of the filter material results in: large filter surfaces low pressure drop high dirt-holding capacities long service life High Pressure Filter HD 7 Filter maintenance By using a clogging indicator the correct moment for maintenance is stated and guarantees the optimum utilization of the filter life. Materials Filter head: Filter bowl: Coating: Seals: Filter media: Spheroidal graphite cast iron (SGI) Cold extruded steel Powder paint NBR (FPM on request) EXAPOR MAX - inorganic multi-layer microfibre web Paper - cellulose web, impregnated with resin Accessories If an electrical indicator is used a transparent socket with LED for optical indication is also available with Part No. DG..

2 Characteristics Operating pressure... bar, min. x pressure cycles Nominal pressure according DIN... bar, min. pressure cycles Quasi-static operating pressure Permissible pressures for other numbers of cycles Operating pressure p [bar] Nominal flow rate Up to 9 l/min (see Selection Chart, column ) The nominal flow rates indicated by ARGO-HYTOS are based on the following features: closed by-pass valve at ν mm /s element service life > operating hours at an average fluid contamination of,7 g per l/min flow volume flow velocity in the connection lines: up to bar 8 m/s > bar m/s Number of cycles n Filter fineness µm(c)... µm(c) β-values according to ISO 889 (see Selection Chart, column and diagram Dx) Dirt-holding capacity Values in g test dust ISO MTD according to ISO 889 (see Selection Chart, column ) Hydraulic fluids Mineral oil and biodegradable fluids (HEES and HETG, see info-sheet.) Temperature range - C... + C (temporary - C... + C ) Viscosity at nominal flow rate at operating temperature: ν < mm /s as starting viscosity: ν max = mm /s 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 7 % 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. Mounting position Preferably vertical, filter head on top Connection Threaded ports according to ISO 8 or DIN. Sizes see Selection Chart, column (other port threads on request).
