Torque arrestors shield submersible well pumps from damaging starting torque and fluctuations, helping extend equipment life and reduce maintenance. This guide highlights five reliable options, summarizing their fit ranges, durability, and installation notes to help you choose the right model for your well size and setup.
| Product | Fits Pipe Size | Notes |
|---|---|---|
| Rubber Torque Arrestor — Simmons | 1″ to 1-1/4″ | Lightweight, basic protection |
| Innconee 1 Pcs 1350 Rubber Torque Arrestor | 1″ to 1-1/4″ pipe; 4″ to 8″ casings | Two-piece, stainless clamps |
| Merrill MFG Submersible Rubber Torque Arrestor | 1″ or 1-1/4″ drop pipe; 4″ to 8″ casings | Two-piece with stainless clamps |
| H2O PRO Submersible Torque Arrestor | 4″ to 8″ pipe casings | Submersible design, torque protection |
When selecting a torque arrestor, consider compatibility with your well dimensions, installation ease, and durability. The following sections detail five products chosen for common residential and light commercial wells, outlining key features and practical usage insights.
Rubber Torque Arrestor By Simmons
The Simmons Rubber Torque Arrestor is designed to provide a simple protective layer above the pump. It is described with dimensions that help ensure fit within typical compact setups. The product emphasizes basic protection against starting torque and potential pump damage, suitable for smaller systems or where budget is a consideration.
Innconee 1 Pcs 1350 Rubber Torque Arrestor
This adjustable arrestor is designed to fit 1″ and 1-1/4″ pipes while expanding to accommodate 4″ to 8″ well casings. It includes a two-piece molded rubber design secured with stainless steel clamps, providing a durable and versatile option that adapts to varying well sizes and helps stabilize the pump during operation.
Merrill MFG Submersible Rubber Torque Arrestor
The Merrill model protects pumps from starting torque damage and clamps to 1″ or 1-1/4″ drop pipes while adjusting to 4″ through 8″ well casings. It uses a two-piece molded rubber construction with stainless clamps, offering a robust solution for mid-sized wells and varying installation requirements.
H2O PRO Submersible Torque Arrestor
The H2O PRO torque arrestor is explicitly designed for submersible well pumps and offers adjustability to pipe casings from 4″ to 8″ inside diameter. It emphasizes reducing damage due to high starting torque, making it a practical pick for deeper, larger-diameter wells or where higher torque events are a concern.
Buying Guide
- Fit and sizing: Confirm pipe diameter (commonly 1″ or 1-1/4″) and the well casing ID (4″–8″). Choose an arrestor that securely fits both the drop pipe and the casing to maximize protection.
- Construction and durability: Look for a two-piece molded rubber design with stainless steel clamps for corrosion resistance and long-term stability in damp well environments.
- Mounting position: Most arrestors are placed directly above the pump. Ensure the chosen model is compatible with your well setup and easy to install without specialized tools.
- Submersible vs above-ground usage: Submersible torque arrestors are designed for enclosed wells and can reduce stress on the motor during startup. Above-ground units are often simpler but may be less protection in certain setups.
- Maintenance considerations: Rubber components can wear over time; check for signs of cracking or loosening clamps. Replace with a model that ships with secure clamps and clear installation guidance.
- Compatibility with pump models: Some manufacturers specify compatible torque arrestors or fittings. Cross-check with your pump’s documentation to prevent fit issues.
- Cost vs value: While basic arrestors are affordable, investing in a two-piece stainless-clamp design may offer longer service life and easier maintenance in challenging wells.
