Appendix AND... 1. Always position a shield between you and any pressurised hydraulic lines when working next to them... or shut the pressure off. 2. Wear safety glasses. 3. Do not use your hands to check for leaks. Do not touch a pressurised hydraulic hose assembly with any part of your body, if fluid punctures the skin, even if no pain is felt, a serious emergency exists. Obtain medical assistance immediately. Failure to do so can result in loss of the injured body part or death. 4. Stay out of hazardous areas while testing hose assemblies under pressure. Use proper safety protection. 5....

Hose Guidelines SAFETY GUIDE AND BASIC FACTORS FOR THE SELECTION, INSTALLATION AND MAINTENANCE OF HOSE AND HOSE ASSEMBLIES Hydraulic hose (and hose assemblies) has a limited life dependent on service conditions to which is applied. Subjecting hose (and hose assemblies) to conditions more severe than the recommended limits significantly reduce service life. Exposure to combinations of recommended limits (i.e., continuous use at maximum rated working pressure, maximum recommended operating temperature and minimum bend radius) will also reduce service life. Laminar flow - In laminar flow, the...

User Guide TECHNICAL INFORMATION – NORMOGRAM OF THE FLOW The normogram herewith is pivotal to help you find the hose diameter by knowing the liquid flow and speed. In order to find the correct diameter you should trace a line between the flow value (l/min) and the suggested speed (m/sec) according to the kind of delivery (pressure or return). The value touched by the line in the central column will indicate the hose ID (mm/inches) that must be used. dash sizes Recommended maximum velocity for suction lines Recommended maximum velocity for return lines Recommended maximum velocity for...

Hose Guidelines It is therefore important to calculate correctly the required flow line sizes. Undersized pressure lines results in high fluid velocity causing an excessive pressure drop, and heat built up, which impair overall system performance. Undersized suction lines can cause cavitation at the hydraulic pump inlet, affecting performance, shortening pump life, and creating excessive noise levels. The flow capacity normogram on page (12) is an aid to determine the correct hose internal diameter size, desired flow rate and recommended velocity. By the use of any two known factors, the...

Hose Guidelines Do not use any ALFAGOMMA hose or fitting for any application requiring non-conductive hose, including but not limited to applications near high voltage electric lines, unless the application is expressly approved in the ALFAGOMMA technical publication for the product, the SAFETY GUIDE hose is both orange in colour and marked “non-conductive”, and the manufacturer of the equipment on which the hose is to be used specifically approves the particular ALFAGOMMA hose and fitting for such use. ALFAGOMMA does not supply any hose or fittings for conveying paint in airless paint...

Hose Guidelines CORRECT ASSEMBLY INSTALLATION Satisfactory performance and appearance depend upon proper hose installation. Excessive length destroys the trim appearance of an installation and adds unnecessarily to the cost of the equipment. Hose assemblies of insufficient length to permit adequate flexing, expansion or contraction will cause poor power transmission and shorten the life of the hose. The diagrams below offer suggestions for proper hose installations to obtain the maximum in performance and economy. Adequate hose length is most important to distribute movement on flexing...
