The slurry pump labyrinth locknut features imperial thread standard. It is mounted on the front end of pump shaft to fasten the impeller. Cooperated with lock washer, it prevents loosening and fixes all wet-end parts on the shaft. It bears slurry impact load and alternating vibration during operation, ensuring synchronous rotation of impeller and pump shaft and avoiding axial shifting of the impeller. It is normally made of high-strength carbon steel or stainless steel. Suitable for imported and domestic AH, ZJ series slurry pumps with imperial threads, it is an indispensable fastening part for shaft end assembly.
