5 Pressure Filter SF Valves Valves The optional valves are fitted as an insert in the filter head and incorporate the spigot on which the element seals. The valve is selected to suit the filter application. HV-O HV-B HV-R Non-by-pass standard insert without any valve function. Element collapse rating should be higher than system pressure By-pass valve which allows oil to bypass the element when the differential pressure across the element reaches +,5 bar (87 +7,25 PSI). (Other pressure settings available on request). The opening pressure should be higher than the p setting of an optional clogging indicator. Low collapse ( bar / 45 PSI p) elements are normally used with this valve. Reverse flow valve is used in systems where there is flow in reverse through the filter. It allows reverse flow without back-flushing the element but does not filter in the reverse direction. Element collapse rating should be higher than the system pressure. HV-N HV-M Non-return valve This valve prevents the oil in the delivery line from draining out while the filter is being serviced. Because there is no by-pass, the element collapse rating should be higher than system pressure. Multi-function valve This valve combines the by-pass, the reverse flow and the non-return functions in one unit. The by-pass opening pressure is +,5 bar (87 +7,25 PSI) p with other opening pressures available on request. The opening pressure should be higher than the p setting of an optional clogging indicator. Low collapse ( bar / 45 PSI p) elements are normally used with this valve.

6 Pressure Filter SF Clogging Indicators Clogging Indicators STAUFF pressure filters have a wide range of clogging indicators available. If no indicator is specified, the port is sealed by a plug (HI-O). The clogging indicators are actuated by the differential pressure ( p) across the element. The special piston design minimizes the effects of peak pressures in the system. An optional thermal lockout (thermo-stop) is available to prevent false indication under cold start conditions. Fluid temperature must be at least 2 C (8 F) for the indicator to function.

94 Off-Line &By-Pass Filters OLS / BPS Technical Data Description Stauff Off-line and By-pass Filter Systems, OLS / BPS, are designed to keep hydraulic and lubrication systems free of particle and water contamination. Stauff OLS and BPS units utilize the Radial Micro Filtration Systems concept for the removal of contamination from hydraulic and lubrication systems. Desiccant Air Breathers, which clean and dry the air entering the reservoir, are also part of this contamination removal system. Stauff RMF Filtration Systems will provide optimal system cleanliness for today s sophisticated hydraulic and lubrication systems. Technical Specification Construction Housing OLS (off-line filter system with integrated motor / pump unit), BPS (by-pass filter system) Anodized aluminium Seals NBR (Buna-N ) Connection 1/4" and 1/2" BSP (for BPS) /8", 1/2", /4" BSP and 18L (for OLS) Differential pressure max.2 bar (9 PSI) across element Max system volume Bypass valve (integrated in filter head) Clogging indicator Media up to 1.8 liter (285 gal).2 bar (9 PSI) for all types Pressure gauge, filled with glycerin Mineral- or lubrication oil, others on request Nominal flow Temperature range between 2.1 l/min (.55 US GPM) and 17 l/min (4.5 US GPM) max 8 C (17 F) media temperature (at a viscosity between 2 and 1 cst) Motor types (for OLS) Several motor types available, for more information please see page F12 (Ordering Codes) F94

95 Off-Line &By-Pass Filters OLS / BPS System Contamination In today's hydraulic market it is an accepted fact that contamination causes 8% of all mechanical failures. This contamination results from the presence of solid particles such as metal, sand and rubber. Changes in temperature cause water vapour to condense, resulting in unwanted water in the oil, the presence of this water accelerates the deterioration of the oil. Mainstream filters are incapable of removing particles, smaller than 2 micron (better known as silt). Fluctuations in pressure and flow result in changing conditions preventing these filters from carrying out fine filtration; most of the silt remains in the system affecting the chemical compostition of the oil. All these problems lead to reduced oil life and increased component wear, maintenance costs and machine down time. Removing silt and preventing the formation of free water will combat these problems. Micro Filtration and Air Conditioning At the heart of the RMF Off-line and By-pass filter unit is the unique microfilter element. This filter is designed with a radial flow path. The element is constructed with.5 micron media, and is therefore able to remove the smallest particles (silt), from the oil. The filter material is composed primarily of cellulose, which is applied by a special wrapping method. This material is capable of retaining solid particles and absorbing water. This helps to prevent chemical deterioraton of the oil and the formation of various acids and sludge. Hydraulic cylinder extension for example, can draw air, solid contamination particles and water vapour into the oil reservoir. OLS / BPS Filter element The water vapour condenses due to temperature changes and causes not only oxidation of the oil, but can also lead to serious mechanical wear in the system. Standard air filters remove a certain amount of solid particle contamination from the air but allow water vapour, to pass through. The Stauff RMF Air conditioners type SDB and SVDB ensure that incoming air is first dried and then filtered. The SDB and SVDB units should be used in conjunction with the OLS / BPS systems in order to provide a more complete filtering system. See Hydraulic Accessories section of this catalog, pages A21 and A22 for more details. SDB Air conditioner F95

96 Off-Line &By-Pass Filters OLS / BPS Technical Data Stauff Radial Micro Filtration Systems distinguish themselves by their high efficiency filter elements which are capable of filtering silt particles down to.5 microns. Two types of Radial Micro Filtration Systems are available. The OLS Series uses an integral pump/motor combination to draw the hydraulic or lubrication fluid from the reservoir, filters it, and returns it to the reservoir. The other type of Radial Micro Filtration System is the BPS Series which uses system pressure to draw a small oil flow from the system which is then filtered and returned to the reservoir. The success of the Stauff RMF Off-line filtration System is due to the design of the element & housing. The element is constructed of.5 micron cellulose media applied with a special wrapping method, providing several hundred layers of filter media. The cellulose fibers also absorb and retain water, which slows down the oxidation process of the fluid. The construction of the housing allows only radial flow through the filter element. This design feature prevents channel forming and subsequent shortcircuiting of the media. The Off-line design maintains a constant flow and pressure through the filter, which does not allow any particle unloading. These design characteristics enable the Stauff RMF Filtration System to maintain a rated filtration efficiency of Beta 2 > 2. This allows the user to maintain fluid cleanliness levels which cannot be reached with conventional full flow filtration methods. Filter Element Design Stauff RMF Filtration Systems also provides a range of SDB/SVDB Desiccant Air Breathers with air flows to 15 l/min (95 US GPM) and water holding capacity of up to 48 g (1. lb). OLS Off-Line Filter System RMF Off-line filter units can be applied to every imaginable industrial application where hydraulic or lubrication systems are present. An integrated motor/pump unit draws out of the tank, filters it and pumps clean oil back into the system. Offline filter units can continue to work even when the main system is not in use. The standard range offers filter units for reservoirs with a capacity of up to 1.8 liter (285 gal). Over the years, RMF Systems have developed considerable experience in the hydraulic and lubrication market cleaning systems to levels not previously possible with conventional methods. The following are a few of the industries that have benefitted. With its integrated motor/pump unit STAUFF OLS filter systems are specially designed for off-line filtration of a hydraulic main system. This allows continuous filtration of the fluid even when the main system has been shut down. The OLS is available with one, two or four filter housings and in two different lengths. The maximum flow for the offline unit goes from 2.1 l/min (.55 US GPM) up to 17 l/min (4.5 US GPM) at a viscosity between 2 and 1 cst. For the OLS you can choose several different motor/pump units, for more information please see page F12 (Ordering Code). steel plastic injection moulding marine petrochemical pulp & paper flight simulator F9

103 Water Absorbing Off-Line Filters OLSW RMF Systems RMF Systems radial micro filter units are characterised by their extremely efficient filter elements which are rated to.5 micron. Specially designed for industrial hydraulic installations the RMF Off-line filters are available in single or multiple housing configurations. The Off-line filter units can easily be mounted to new and existing hydraulic installations. By means of an integrated motor/pump unit and an Off-line filter, the oil is pumped from the reservoir through the filter unit and after filtering the oil is then returned to the tank. Economical The hydraulic market accepts that 8% of mechanical failures are caused by contamination in the system. The RMF Water Absorbing Off-line filters attack this contamination at source and in addition to solid particles, these filters are also capable of removing large quantities of water from the oil. This prevents the catalytic reaction of water and solid particle contamination, resulting in extended useable oil life. In recent years RMF Systems have developed a great deal of experience in cleaning and drying hydraulic and lubrication systems in the following markets: - steel industry - maritime industry - petrochemical industry - paper industry The application of RMF filters results in lower component failure rates, less down time and less system maintenance. Water Absorbing RMF Water absorbing filters are Off-line units that use special water absorbing spin-on filter elements as a prefilter. The fluid is pumped through the pre-filter which removes most water and larger solid contamination, in the second stage the fluid passes through the RMF micro filter where final water removal takes place as well as solid removal down to.5 micron. Advantages Extremely clean oil due to the high filtration efficiency ß2 > 2, Prevention of channel forming by radial filtration direction Increased flow capacity Increased dirt holding capacity Large water holding capacity Compact and easy-maintenance design Longer usage life for oil and components F1

107 By-Pass Filters BPS Technical Data By-pass Filter BPS STAUFF BPS by-pass filter can be used for OEM first fit applications as well as for retro-fitting.the filtration is done in a by-pass configuration from the main hydraulic system. The STAUFF BPS Filter systems are available with one filter housing (BPS-1A, maximum flow 2,1 l/min /. US GPM) or with two filter housings (BPS-2A, maximum flow 4,2 l/min / 1.1 US GPM) at a viscosity between 2 and 1 cst (1-75 SUS). The RMF By-pass filter units are especially designed for mobile applications in hydraulic and/or transmission systems. In the absence of a pumped system, the oil is drawn from the main system by means of a specially designed and integrated flow valve. The amount of oil extracted at any one time is insignificant therefore ensuring that it will not affect the working of the main system. Most commonly used biodegradable oils in the mobile sector are suitable for filtration with RMF filter elements. RMF Systems have been applied on a wide range of mobile hydraulic machinery, cleaning fluids to levels not previously possible with conventional filtration methods, resulting in dramatic increases in component life.

112 Off-Line &By-Pass Filters OLS / BPS Advantages The advantages of RMF Systems Less malfunctions The tolerances between moving parts in servo valves and proportional valves are constantly reducing. The result is that even the smallest amounts of silt can cause damage to the system. RMF filters remove this silt. Protection of expensive main stream filters RMF Systems filters are applied in By-pass or Off-line configurations and constantly clean oil from the reservoir. The oil which reaches the main stream filter is therefore cleaner, and allows longer usage life of this expensive filter. The main stream filter then acts primarily as an emergency filter. Extended usable life of the oil Frequent oil changes are generally the result of chemical deterioration of the oil caused by the oil oxidation process. This process is brought into action by the presence of silt. If water is also present, this acts as a catalyst and the oxidation process is accelerated. RMF filters remove silt AND water from the oil. Less machine down time Reduction of defects caused by worn components and less frequent oil changes mean an increase in production time. Less frequent oil changes Increasingly strict environmental laws in the area of oil changes, oil storage and the disposal of used oil leads to corresponding cost increases. RMF filters lengthen fluid life, therefore cutting fluid costs. RMF Characteristics in short The oil filters have: - a filter fineness of.5 micron (ß.5 2, ß 2 2,) - large particle collection capacity - high filtration capacity due to depth effect - large water adsorption capacity RMF Systems filters: - do not adversely affect viscosity or additives - do not remove additives - reduce the oxidation process - reduce the forming of acids - SAVE COSTS Measuring points To facilitate quality control of the oil, every RMF Systems oil filter is equipped with two quick connect measuring points to which a particle counter can be attached. This offers a convenient point in the circuit to measure the oil cleanliness level on-site and under working conditions. The measuring points also allow oil samples to be drawn for external analysis. The solution RMF Systems offer the most complete and efficient filter series available today. RMF Systems is THE solution to your contamination problems: simple to fit, equipped with extremely efficient filters and offering the opportunity for simple control of oil cleanliness. Stauff RMF has a wide range of applications on which we have a substantial database with case studies and application knowledge. Please contact your nearest Stauff RMF distributor for specific information on your desired application. Stauff RMF offers solutions for installations/equipment in the following segments: Mobile Equipment: Mining Harvesting Forestry Agricultural Off-road Fishing Road construction Cranes Airport equipment Industrial Equipment: Flight simulators Pulp and paper Food processing Presses Automotive industry Timber plants Plastic & rubber Metal industry Cement & concrete Material handling Bridges/Hydraulic locks/water works Petrochemical industry Power stations F112

113 Off-Line &By-Pass Filters OLS / BPS Replacement Elements The unique RMF Filter The principle of the RMF System is based on the unique original filter elements. With a filter fineness of.5 micron they have the capacity to remove even the smallest of dirt particles from the oil. The micro filter works as a fine filter through which oil passes radially, from the outside to the inside. The filter elements are made entirely of cellulose and are specially designed for hydraulic and lubrication systems. The use of cellulose as the filtration material has the added benefit that water can be absorbed. Water in oil creates a chemical reaction, which seriously deteriorates the oil. Original elements The use of original RMF Systems filter elements will result in extreme fluid cleanliness and low water contamination levels in the fluid. Through a carefully monitored quality control process excellent pressure drop curves, filter efficiency and dirt holding capacity are ensured. Applications The original filter elements are used in combination with RMF Systems filter housings in an endless range of industries. Some Examples are: plastic industry steel industry concrete and cement industry petrochemical industry maritime industry paper industry forestry industry.

115 By-Pass Lube-Oil Filter BPLS zmaintenance is essential for the efficient functioning of engine equipment. However, it is always a critical decision between the quality of the maintenance and the costs involved. Optimal maintenance efficiency combines maximum achievement of the maintenance goal (protection and prolonged usage life of the object) with minimal use of means (costs). The Stauff RMF by-pass filter is unique in that it not only achieves the goal, but saves on costs. The Stauff RMF by-pass filter keeps the oil clean, resulting in significant technical, environmental and financial benefits thanks to reduced wear and tear on equipment and machines and prolonged oil life time. Stauff RMF systems BPLS by-pass filters are used as an additional micro filter connected in by-pass to the conventional main stream filters on engines (and automatic transmissions.) Most contamination is much smaller than 15 micron in size, but full flow filters generally do not filter below this level. This results in a lot of harmful contamination passing through these filters and remaining in the system. Stauff RMF Systems bypass filters are capable of filtering down as low as,5 micron without detriment to the lubrication circuit. (see schematic) Full flow filter 15µ Whatever the application, the benefits of the Stauff RMF Systems by-pass filters are all based on maintaining a higher quality and cleanliness level of the oil and thereby avoiding the multiple problems that can be caused by fluid contamination.
