Chesterton 14K Restrictor Bushings
Reduce Flush Requirements and Increase Reliability

  

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton 14K Restrictor Bushings are designed for use in rotary equipment to form a barrier between the sealing device in the stuffing box or the pump impeller housing and the fluid in the mixing tank. The restriction produced reduces flush requirements and helps to prevent suspended abrasive particles from entering the stuffing box area.​

Split design simplifies installation
Prevents particles from entering the stuffing box, extending packing and seal life
Tapered lip design controls fluid bypass
Designed for pumps and other rotating equipment such as agitators, mixers, and refiners
