CAMPBELL Torque Arrestor & Pitless Adapter

These torque arrestors hold submersible deep-well pumps in place inside the well casing and prevent damage from the torque produced by the pump motor and the impellers. Torque arrestors connect around the drop pipe and above the submersible-well pump, then they are clamped down on both ends with the expandable section opened slightly wider than the diameter of the well casing. They keep pumps from twisting and keep them centered in the well casing so the pumps will not slam against the side of the casing and damage it.
