“Extreme care must be taken in the correct selection, installation and maintenance of matched components in any hydraulic system, because hose assemblies can be highly dangerous if misapplied or inadequate attention is given to maintenance,” says Joanne Tarr, BMG’s national product manager.
“When selecting a hose, it is important that the working pressure is higher than the maximum operating pressure of the system. Fluid temperature, either in motion or with the equipment at a halt, should never exceed the maximum working temperature recommended for each hose. It is also critical to consider the surrounding temperature, especially from heat sources in the proximity of the hose assembly.
“BMG recommends that hydraulic hose assemblies are always inspected and pressure tested against leakage and malfunction before installation. Installations that do not comply with the adequate geometry of the hose assembly, or where the application of the system exceeds hose specifications, can lead to premature failures.”
Fluid compatibility with the hose and coupling should also be verified to avoid degradation through chemical attack. BMG’s comprehensive catalogue of hydraulics hoses and fittings includes an easy to follow reference fluid compatibility and resistance chart, technical information on BMG’s extensive range of hoses, fittings and adaptors, as well as critical information on correct product selection, installation and safety guidelines.
Eaton Winner braided hydraulic hose and fittings
New to BMG’s portfolio of components for fluid power systems and general industrial applications are Eaton Winner braided hydraulic hoses and fittings. These perfectly matched hoses and fittings ensure safe and reliable conveyance of petroleum and water-based hydraulic fluids at high pressure, even in the most demanding environments.
Currently, Eaton Winner hose EN853 1SN (EC110) and 2SN (EC210) and a wide selection of two piece, non-skive fittings are available nationally from BMG’s distribution network. This range, which is complemented by adaptors, steel tube fittings and high pressure hoses, will be extended to include other hoses in the Eaton range, according to market demand.
Winner hose EN853 1SN (EC110), with a synthetic rubber tube and cover, as well as single wire braid reinforcement and a white ink transfer lay-line, is designed for petroleum and water-based fluids at operating temperatures between -40 and 100°C. This range has a maximum working pressure of 225 bar and a minimum bend radius of 100 mm.
Winner hose EN853 1SN (EC210) has a double wire braid reinforcement, with a synthetic rubber tube and cover and a green ink transfer lay-line. This hose has a maximum working pressure of 400 bar and a bend radius up to 630 mm.
Other products available from BMG’s fluid technology division include valves, accumulators, cylinders, heat exchangers, hydraulic motors and hydraulic plumbing, pumps and reservoir accessories.
The company’s fluid technology services encompass project engineering and consulting, cylinder design and manufacture, hydraulic training, repair and testing, and onsite container services.
