HEALTH & SAFETY The Rotary Unions shown in this leaflet should not present any hazard when correctly fitted To ensure satisfactory performance, every Rotary Union is run-in and leakage tested before despatch. It is essential to use the correct hand of rotary connection thread to ensure the Rotary Union will not unscrew (see the Installation Instructions). If a shaft reverses rotation then a flanged connection rather than a screw thread is strongly recommended. At some time the seals in the Rotary Union will leak, so inspect regularly, also ensure that leakages are not hazardous to personnel and that the Rotary Union is removed for repair immediately. If leakages are not attended to promptly, bearing seizure may occur causing flexible hose failure and massive leakage. Fit protective guards if leakages are likely to be hazardous to personnel or equipment. With oil systems minor leakages occur due to the natural characteristics of oil preventing seal faces from contacting fully. WE MANUFACTURE MANY SPECIALS.
