Tank mounted return line filters

THE IMPORTANCE OF AN EFFICIENT FILTRATION The main cause of anomalies in hydraulic systems has to be attributed to the presence of contaminants in the fluid. The nature of the contaminant may be: gaseous, namely air mixed with the fluid; fluid, it depends on water penetrating the fluid; solid, therefore particles of various origins and dimensions. Customers who operate equipments are always focused on obtaining the best possible performance, lower energy consumptions and greater respect for the environment. These characteristics can be attained by using top quality components in the hydraulic...

TECHNICAL CHARACTERISTICS The tank mounted filters HF 547 series are specifically designed to be directly connected on the return line of hydraulic circuits and provide versatility to safeguard the circuit components from contaminating particles.

SIZING – PRESSURE DROP The total pressure drop of the filter is calculated by summing the pressure drop value in the housing to the one in the filtering element. Total Dp = Dp in housing + Dp in element In filters of HF 547 series in normal working conditions, the total Dp must not be more than 5.8 psi (0,4 bar). To establish the values of pressure drop involved, the following pages provide some diagrams with curves referred to the use of mineral oils ISO VG46 with kinematic viscosity of 120 SSU (30 cSt) and density of 7.29 lb/gal (0,856 kg/dm3). Calculation example Filter HF547-20.201-AS-FG025-B17-GG-B-S-Z-XN-G-YN-A-K...

PRESSURE DROP CURVES THROUGH THE BY-PASS VALVES The pressure drop values are directly proportional with the specific weight of the fluid and do not affect the establishment of the total pressure drop of the complete filter. The curves are obtained in the following conditions: Mineral oil type ISO VG46 Kinematic viscosity 120 SSU (30 cSt) Density 7.29 lb/gal (0,856 kg/dm3).

ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONS ASSEMBLY REPLACING ELEMENT Once you have checked the integrity of the filter inside its package, proceed as follows: A Take off the protection cap from the inlet port. Ensure the filter to the tank through the flange's holes (pos.3) with a tightening torque of 44 lbf in (5 Nm). Once the working hour limit indicated in the manteinance instructions of the system is reached or when the clogging indicators point out the limit pressure drop created inside the filter, the element must be replaced. Pay attention to the drainage of hydraulic oil, therefore...
