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 502 and HF 508 series are specifically designed to be directly connected on the return line of hydraulic circuit to safeguard it from contaminating particles. HF 508 series is available with double inlet port with SAE 3000 threads. l Flow up to 264 US gpm (1000 l/min) l Extension on the oil way out of the pipe union l Fluid-decelerating diffuser OPERATING TEMPERATURE With Buna seals With Viton seals Reinforced nylon Steel Buna - Viton Zinc plated steel Inner tube Zinc plated steel Steel Filter media DEGREE OF FILTRATION Absolute Filtration...

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 502 and HF 508 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 SAE 10 with kinematic viscosity of 120 SSU (30 cSt) and density of 7.29 lb/gal (0,856 kg/dm3). Calculation example Filter HF502-30.239-AS-RP025-B17-GH-B-H-Z-XN-G-YN-K...
