THE IMPORTANCE OF AN EFFICIENT FILTRATION

Tank mounted return line filters HF 57 / HF 575 / HF 578 series

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 system for generating and regulating the fluid power, which are also more sensitive to the presence of contaminants in the fluid. Starting from these requirements, we understand how important and fundamental it is to prevent the presence of air and water from mixing in the fluid tank by using dedicated solutions. It is also crucial to limit the presence of solid particles in the hydraulic circuit through a suitable filtering system, which is indispensable to maintain the project requirements of the system over time and to keep running costs low. The correct choice of a filter and its optimum position in the hydraulic system requires the same care and experience needed to choose all the other components. The use of filters with larger filtering surfaces reduces, at equal flow rates, the superficial contaminant load and therefore the filter's life is extended proportionally. To maintain the maximum efficiency of the system, the filters must have a clogging indicator showing the differential pressure on the filtering cartridge and to immediately point out when the cartridge needs replacing in order to prevent the bypass valve from opening. The following factors should be analysed when choosing the ideal filter: The filtration degree required to protect the most sensitive component from contamination The points of the circuit in which the filters have to be installed The working pressure of the system The maximum flow rate and the type of fluid to be filtered The duty cycle The retention efficiency of the filtering cartridge The contaminant accumulation capacity of the filtering cartridge The working ambient temperature Each filter used generates a pressure drop that increases continuously as time goes by. This pressure drop represents an efficiency index of the filter itself. When the hydraulic system is about to be assembled, all the components must be perfectly clean and the fluid has to be added through a device complete with a filter. During the test phase, it is advisable to run some work cycles at low pressure in order to create the best possible conditions for all the components.

TECHNICAL CHARACTERISTICS Tank mounted return line filters HF 57 and HF 578 series along with in tank filters HF575 series are specifically designed to be directly connected on the return line of hydraulic circuit to safeguard it 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 p p in housing + p in element In filters of HF 57 and HF 578 series in normal working conditions, the total p must not be more than 5.8 psi (,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 1 with kinematic viscosity of 12 SSU (3 cst) and density of 7.29 lb/gal (,856 kg/dm 3 ). Calculation example Filter HF573.26ASFG25B17GHBHRXNGYNGD Flow rate= 63 US gpm (24 l/min) Kinematic viscosity: 12 SSU (3 cst) Oil density : 7.29 lb/gal (,856 kg/dm 3 ) Filtering degree: 25 m Data obtained from the diagrams: p in housing = 3.2 psi (,22 bar) (page 4) p in element = 2. psi (,14 bar) (page 8) Total p = 3.2 + 2. = 5.2 psi (,36 bar) ( p is lower than maximum value admitted therefore sizing is correct). If oil with different kinematic viscosity and different density is used, the values obtained from the diagrams will be recalculated considering the following indications: 1) The pressure drop of the housing is proportional with the oil density, therefore for oil with density different to 7.29 lb/gal (,856 kg/dm 3 ) the value of the p in the headbowl will be: p in housing = Or p in housing = p of diagram (psi) Oil density ( lb/gal) 7.29 (lb/gal) p of diagram (bar) Oil density ( kg/dm 3 ),856 (kg/dm 3 ) [psi] [bar] 2) The pressure drop of the element is proportional with the oil density and kinematic viscosity, therefore for oil with density different to 7.29 lb/gal (,856 kg/dm 3 ) and kinematic viscosity different to 12 SSU (3 cst) the value of p in the element will be: p element = p of diagram (psi) Or p element = p of diagram (bar) Oil density (lb/gal) Oil viscosity (SSU) 7.29 (lb/gal) 12 (SSU) Oil density (kg/dm 3 ) Oil viscosity (cst),856 (kg/dm 3 ) 3 (cst) [psi] [bar] Now you sum the values of the pressure drop of the housing to the value of the pressure drop of the filtering element, always making sure the total p does not exceed the pressure limit of 5.8 psi (,4 bar). 2 2 ICAT12

HF 575 ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONS MOUNTING Once you have checked the integrity of the filter inside its package, proceed as fallows: A B C D E F G H Take off the filter packaging. Oil the perch gasket (pos.1). Remove the tank's cover. Insert the filter in the dedicated seat of the tank. Insert the placement spring between the tank's perch and cover, as indicated on page 19. Close the tank's cover. Start the circuit for a few minutes. Make sure there are no leaks. REPLACING ELEMENT 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 prepare suitable containers to collect it. Proceed as follows: A Stop the system in "machine stopped" status. B Secure any shutoff valves on the Hydraulic circuit. C Remove the tank's cover and the placement spring (pos.14), so extract the filter. D Unscrew the stopdiskette nut (pos.1), extract the pushdiskette (pos.2) and the bypass spring (pos.3).

HF 57 AND HF 578 ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONS MOUNTING Once you have checked the integrity of the filter inside its package, proceed as follow: A B C D E F G Take off the protection cap from the inlet port. Secure the filter in the tank through the holes in the body's flange (pos.3) tightening them as follows: HF 572 = 44 lbf in (5 Nm) HF 573 e HF5783 = 62 lbf in (7 Nm) HF 574 e HF5784 = 88 lbf in (1 Nm) Connect the piping of the return line to the inlet port using the tightening torque indicated on pages 22, 23 and 24. In the presence of secondary inlet ports, prepare the required connections. If the filter has a clogging indicator (pos.23 24 25 26), take the protection cap off and screw the indicator in the dedicated seat, then tighten to a tightening torque of 266 lbf in (3 Nm). If the indicator is electric, complete the required connections. Start the circuit for a few minutes. Make sure there are no leaks. REPLACING ELEMENT 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 prepare suitable containers to collect it. Proceed as follows: A Stop the system in "machine stopped" status. B Secure any shutoff valves on the hydraulic circuit. C Unscrew the cover's screw (pos.22) (except HF572), take off the closing cap (pos.2) and extract the perch part with the "HF 575" element (pos.4). D Unscrew the stopdiskette nut (pos.5), extract the pushspring diskette (pos.6) and the bypass spring (pos.7). E Remove the clogged element (pos.8) from the perch (pos.15); if there is a megnetic set (pos.11 pos.12) remove the accumulated brassy contaminant. F Check out that the Oring (pos.13 pos.14) are not damaged, otherwise replace them and consequently position the new ones correctly. G Insert the new filtering element (pos.8) on the perch (pos.15) preemptively lubricating the ORing placed in the element inner cap. H Position the bypass spring (pos.7), the pushspring diskette (pos.6) and the stopdiskette nut (pos.5). For a correct bypass calibration, make sure that pushspring diskette gets in contact with the beat in the central bar (pos. 9). I Put the perch part with the "HF 575" element (pos.4) inside the filter's body (pos.3). L Check out that the Oring (pos.19) is not damaged, otherwise replace it and consequently position the new one correctly. M Insert the placement spring (pos.18) in the dedicated seat of the filter's cover (pos.2), reassemble it screwing the fixing screws (pos.22) with a tightening torque of 44 lbf in (5 Nm). N Reopen the eventual valves closed before. O Start the machine for a few minutes. P Make sure there are no leaks. Pos. Description Pos.
