UNIONS INSTALLATION
Even if the ROTOFLUX unions are rugged and stout, they must be handled with care. For a proper installation we suggest to proceed as follows:
• Make sure that the fluid system, when new, has been properly cleaned and made free from any machining burr or abrasive particle. In existing fluid system make sure that the filter quality and functionality are in accordance with the normal requirements of hydraulic systems.
• Clamp in a bench vice the rear of the union and screw up the flexible hose (sketch 1).
Do not use solid pipes.
• Install the rotary union on to the shaft (sketch 2).
• Connect the flexible hose to the supply line. Make sure that the union is not installed taut (sketch 3).
• When using metallic flexible hoses in short space with sharp curves, use rigid 45° or 90° elbows to avoid undue stresses (sketch 4).
• Check that the union does not rotate eccentric or wobbling. • If the fluid is hot or dangerous for any reason, apply a union guard.
• When required, lubricate periodically the union.
• Inspect periodically the union to service it and detect any leakage.
