Simmons 1350 Rubber Torque Arrestor
The Simmons 1350 rubber torque arrestor is designed to minimize starting torque impacts on small-diameter drop pipes. It supports a range from 1″ to 1-1/4″ and ships with a simple installation configuration. The package dimensions emphasize its compact nature, making it suitable for tight well installations while offering a basic level of torque protection. If you’re working with compact pump assemblies in tighter wells, this unit provides a straightforward, affordable option.
Merrill MFG Submersible Rubber Torque Arrestor
The Merrill MFG model is a versatile rubber torque arrestor designed to clamp to 1″ or 1-1/4″ drop pipes and adjust to fit 4″ through 8″ well casings. It includes two stainless-steel clamps, providing a two-piece molded rubber construction that helps absorb recoil and reduce motor strain during startup. This unit is well-suited for homeowners replacing clamps or upgrading older installations where flexibility and a robust securing solution are needed.
H2O PRO Submersible Torque Arrestor (4″–8″ ID)
This submersible torque arrestor from Star is adjustable to pipe casings with an inside diameter ranging from 4 to 8 inches. It’s designed to protect pumps from high starting torque, a common issue in deeper or larger-well installations. The adjustable feature makes it a flexible choice for a variety of well configurations, especially where standard sizes do not fit perfectly.
H2O PRO Brass Adapter With Rope Loop
The brass adapter offers a practical way to secure a submersible pump within a well using a rope loop eyelet. This connector facilitates attachment to flexible pipes and is compatible with various threaded or pipe-end configurations, supporting safer, more secure pump installation. It’s a useful accessory when pairing a torque arrestor with flexible piping in a well system.
Red Lion RL12G07-2W2V Deep Well Pump
Red Lion’s RL12G07-2W2V is a 4-inch submersible deep well pump with a 3/4 HP motor designed for up to 12 GPM, suitable for deeper wells. It includes a built-in check valve and a suction screen to reduce debris and cycling. While not a torque arrestor itself, it represents a common companion in well systems where torque protection is part of a broader pump protection strategy. It’s a useful option to consider when evaluating overall well pump assemblies alongside torque arrestors.
Red Lion RL12G10-3W2V Deep Well Pump With Control Box
This model from Red Lion includes a control box for added convenience and protection, with a 1 HP motor delivering up to 12 GPM. It is designed for 4-inch wells and deeper, with features such as a built-in check valve and suction screen. While the primary focus is pumping capability, pairing such a pump with a torque arrestor can further reduce the risk of motor strain during starting and cycling in challenging well conditions.
Red Lion RL12G10-2W2V Deep Well Pump
Another Red Lion option offers a 1 HP, 12 GPM configuration ideal for larger residences or properties with demanding water needs. It shares many features with the 3W model, including built-in protection elements to help extend motor life. Consider this pump alongside torque arrestors when planning for efficient, reliable well performance and reduced startup stress in larger systems.
Buying Guide: Key Purchase Considerations
- Well diameter and casing size: Choose a torque arrestor that fits your well’s internal diameter and your pump’s drop pipe or tubing size to ensure a secure fit and proper torque absorption.
- Clamp compatibility: If you’re repurposing or upgrading, verify whether clamps are included and whether they’re stainless steel for corrosion resistance in water environments.
- Material and durability: Rubber arrestors dampen shock and reduce vibration, while metal components provide ruggedness for long-term use. Consider the operating environment and the potential for mineral buildup.
- Ease of installation: Look for arrestors that clamp or thread easily to your existing pipe, with clear instructions. Adjustable models offer flexibility across multiple well sizes.
- System compatibility: If pairing with a deep-well pump, ensure the arrestor works with your pipe size and doesn’t impede water flow or maintenance access.
- Maintenance and longevity: Rubber and stainless-steel components resist wear better under repeated start-stop cycles. Check for warranties or replacement parts where available.
- Overall system protection: A torque arrestor isn’t a substitute for proper pump sizing and electrical protection. Use it as part of an integrated approach to minimize startup torque and motor stress.
- Application scope: For small-diameter wells, prefer compact arrestors; for larger 4″–8″ casings, choose adjustable models that accommodate diameter variations without compromising grip.
In summary, selecting the right torque arrestor involves considering pipe size, well casing, and the typical load your submersible pump experiences at startup. The options highlighted here provide a range of choices from compact, clamp-on models to adjustable designs suitable for larger casings, along with related components that support secure, efficient well performance.
