Torque Arrestor for Pumps

Reduce Pump Stress with the Campbell Torque Stop Arrestor

The Campbell Torque Stop is a crucial component for maintaining the stability and integrity of submersible pump installations. Positioned directly above the pump, this torque arrestor absorbs start-up torque and minimizes pipe rotation inside the well casing—helping prevent wear on electrical leads, threaded connections, and pump components.

Core Features & Advantages

• Minimizes Pipe Rotation: Effectively dampens torsional forces during pump start-up to protect system integrity.
• Reliable PVC Construction: Manufactured from FDA-approved flexible PVC designed for demanding well environments.
• Fits Common Configurations: Compatible with 4" to 8" I.D. well casings and 1" to 2" drop pipe sizes.
• Secures with Stainless Clamps: Includes two corrosion-resistant stainless steel bands for reliable attachment to the drop pipe.
• Adjustable to Fit: PVC fins can be trimmed on-site for a tight fit in varying casing diameters.

Product Specifications

Installation Guidance

Installation requires only basic tools. For best performance, center the torque stop within the casing and trim fins as necessary to ensure it firmly anchors the pump assembly. For deeper installations or high-load applications, licensed pump professionals are encouraged to handle the install to maintain proper system alignment and avoid premature equipment wear.

Where It’s Used

• Submersible pump installations in 4"–8" well casings
• Systems using long drop pipe lengths or heavy-duty pumps
• Applications with significant motor start-up torque

Contractor Insight

Torque arrestors are standard in professional well installations for a reason. Start-up torque can lead to pipe loosening, wire fatigue, or even pump misalignment—issues that result in expensive callbacks. The Campbell Torque Stop offers a cost-effective way to enhance system reliability and reduce stress on the pump, pipe, and wiring over time.
