HOSES CATALOGUE

Introduction This catalogue has been designed to provide a complete guide to our hydraulic hoses and offer useful technical data for the product range. The hydraulic hoses shown in this catalogue are designed to meet or exceed DIN, SAE, and EN specifications, providing reliability in demanding service conditions of applications such as: ♦ Earth moving equipment. ♦ Tractors. ♦ Hydraulic cranes. ♦ Injection moulding presses. ♦ Fork lifts. ♦ Drilling equipment. ♦ Agricultural machines, etc. Hydraulic hoses suitability Hydraulic hoses suitable for hydraulic fluids on mineral oil and synthetic...

Hose Selection SELECTION CRITERIA TEMPERATURE a) Fluid Temperature b) Ambient Temperature PRESSURE APPLICATION a) Equipment Type b) Working Pressure c) Pressure Surges d) Environmental Condition e) Mechanical Loads f) Hose construction g) Abrasion a) Flow area change b) Friction c) Temperature of fluid d) Length of assembly e) ID of hose f) Pressure drop

Selection Criteria SIZE The Inside Diameter of the hose must be adequate to keep pressure loss to a minimum and avoid damage to the hose arising as a result of heat generation or excessive turbulence. Hose Outside Diameter can be a critical factor when hose routing clamps are used or hoses are routed through bulkheads. Check individual hose, specification tables for O.D.s TEMPERATURE Both fluid and ambient temperature must be considered while selecting a replacement assembly. The hose selected must be capable to withstand minimum and maximum temperature of the system. While selecting a hose...

Determination of Nominal Diameter Nomogram for determination of nominal diameter The nomogram can be used as an aid to select the nominal diameters of hose and pipe assemblies. Example Rate of flow Q=50 I/min (left-hand scale), chosen speed V=approx. 4m/sec. (right-hand scale). The point of intersection on the middle scale gives a nominal diameter of 19.1 mm. Other parameters of the installation, such as length of hose assemblies, number of valves, viscosity of the oil and maximum permissible pressure loss, must be taken into account when determining final nominal diameters. The nominal...

Calculation the Length of Hose Assemblies Calculating the Hose Length The Service life of hose assemblies can be increased by proper measurement and installation. Please follow the following instructions: Calculation of flexible hose assemblies Overall length L = 2B + 3.14.R + C R > minimum bend radius Overall length Additional length C should be allowed for if vertical movement takes place The following table gives, depending on the hose diameter, the minimum length B that should be left behind of the end of the fittings of a hose assembly. DN Ø 6 8 10 12 16 20 25 32 40 B (mm) 90 100 110...
