HF 502 / HF 508 series

Product catalog summary
Introduction
The document highlights the critical role of efficient filtration in hydraulic systems, noting that contaminants like air, water, and solid particles can lead to system anomalies. Effective filtration is essential for maintaining system performance, reducing energy consumption, and ensuring compliance with environmental standards.
Specifications
The HF 502 and HF 508 series are tank-mounted return line filters designed to protect hydraulic circuits from contaminants. Key specifications include a flow capacity of up to 264 US gpm (1000 l/min), materials such as aluminum and reinforced nylon or steel, compatibility with various fluids, a working pressure of 116 psi (8 bar), and a burst pressure of 232 psi (16 bar). Operating temperature ranges vary based on seal type (Buna or Viton).
Filtration and Pressure Drop
The document emphasizes the importance of selecting the correct filter based on filtration degree, installation points, system pressure, flow rate, and ambient temperature. It explains that each filter generates a pressure drop, which serves as an efficiency index, and the total pressure drop should not exceed 5.8 psi (0.4 bar) under normal conditions.
Pressure Drop Calculations
Pressure drop is calculated by summing the values in the housing and the filtering element. Formulas are provided for recalculating pressure drops when using oils with different densities and viscosities.
Graphs and Diagrams
Pressure drop curves for various filter configurations and conditions are included, using mineral oil type SAE 10 with specific viscosity and density parameters. These curves assist in determining the pressure drop across different filter elements and housings.
Conclusion
Proper filter selection and maintenance are crucial for the longevity and efficiency of hydraulic systems. The HF 502 and HF 508 series provide robust solutions for managing contaminants and maintaining optimal system performance.
Additional Specifications
Detailed specifications for various filter models, including thread sizes, dimensions, and torque requirements for mounting and assembly, are provided.
Mounting Instructions
Instructions include removing the protection cap, securing the filter in the tank, connecting return line piping, installing clogging indicators, and checking for leaks after starting the circuit.
Replacing Element Instructions
Steps include stopping the system, removing the cover and clogged element, cleaning the bowl, checking O-rings, inserting a new element, and checking for leaks after reassembly.
Ordering Information
Codes for ordering complete filters and replacement elements are detailed, including options for filtering surfaces, degrees of filtration, by-pass valves, inlet ports, seals, and accessories.
Product Range
A full range of filters suitable for various hydraulic circuits is listed, including suction filters, tank-mounted return line filters, in-line filters, and accessories like filler breathers and pressure gauges.

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...

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).
