About Hydac Filtration, Accumulators and Fluid Sensors

The filter element is the item most often ordered and the one most often got wrong. An element is defined by its length and diameter, by its filtration rating and the medium it is made from, by its collapse pressure rating, and by the seal material. Filtration rating is not a single number to be matched loosely: a glass fibre element and a paper element of the same nominal micron rating have very different beta ratios and dirt holding capacity, and substituting one for the other changes the cleanliness the system achieves. Collapse rating matters on return line filters where cold start pressure is high. Accumulators store energy in a gas volume separated from the fluid by a bladder, diaphragm or piston, and are specified by volume, maximum working pressure, port size and gas pre-charge, with the pre-charge being a commissioning value rather than a fixed part attribute. Pressure switches and transmitters in the EDS family convert system pressure to a switched or analogue output, and are ordered by pressure range, output type and connection.

Hydac Filtration, Accumulators and Fluid Sensors in Saudi Arabia

Hydraulic and fluid conditioning equipment of this type is used wherever oil systems have to stay clean in a hot, dusty environment. Steel and aluminium plants, cement works and mining operations run filtration on press, crusher and mill hydraulics. Petrochemical and refinery units at Jubail and Yanbu filter lubrication and control oil on turbines, compressors and control valve actuators. Power generation uses accumulators on governor and control systems, and water utilities filter hydraulic oil on gate and valve actuation. Local conditions load these products hard. Ambient temperatures raise reservoir and oil temperatures, which reduces viscosity, increases internal wear and shortens element life; airborne dust ingested through breathers is the main source of contamination in Saudi plants, so breather and element replacement intervals are shorter here than a European maintenance schedule assumes. Accumulator gas pre-charge also drifts with temperature and should be checked as part of routine inspection.

Ordering and lead time

Quote the Hydac type code as printed on the element end cap or the housing plate, for example a numeric reference such as 909622, or the full element designation if it is legible. Element codes carry length, diameter, filtration rating, medium and seal, and none of these can be reconstructed from "a 10 micron element". If the marking is gone, send the housing type and a photograph of the old element with its overall length and outside diameter measured. For accumulators, state volume, maximum working pressure, port connection, bladder or piston type and the fluid in use, and note that gas pre-charge is set on commissioning. For pressure switches and transmitters, give the pressure range, output type, electrical connection and process port thread. Items are sourced to order with a typical lead time of three weeks and delivered duty-paid to site.
