A sealing device for a pump has a sleeve, a rotary collar, a first O-ring, a stationary collar, a mounting bracket, a second O-ring, a mounting collar and a locking pin. The rotary collar, stationary collar, mounting bracket and mounting collar are mounted around the sleeve. The first O-ring is mounted between the sleeve and the rotary collar. The second O-ring is mounted between the mounting bracket and the stationary collar. The locking pin is mounted securely between the mounting bracket and the stationary collar. The O-rings provide multi-sealing functions. The locking pin prevents relative rotation between the mounting bracket and stationary collar. |
