Torque-arresters for Sub-Pumps....

[Andre ROUSSEAU]

Hi, I have read some interesting discussions from back in 2010 on the subject of anti-torque stops. These mainly describe the waisted expanding bladder type. Another type I've seen a photo of resembles a curved-spoked wheel reminiscent of the circular support disc on the end of a ski-pole. Does anyone know who makes this type (brand-names, model-numbers, web-links, etc.). Also, same query but for centring supports, as well.
Cheers folks.

Those end of the ski pole things are probably stand offs or wire protectors, not torque arrestors. Torque arrestors and standoffs are only needed when the pump is cycling a lot. I never use either as they are just extra stuff that can either fall in the well or stick and keep you from getting the pump out of the well. Use double jacketed wired taped to the pipe every 10-20 feet, and keep the pump from cycling with a Cycle Stop Valve. Not only does the CSV keep cycling from wearing out the wire or unscrewing the pump, but solves all the other problems caused by too much cycling.

My rule of thumb is one TA 48 style torque arrestor per 100' of pump setting.

The only time I use a torque arrestor is on poly pipe. And since I never install poly pipe.......

why do you never install poly?

Poly isn't really designed for downhole applications. It's too flexible, it's extruded and rolled into coils and will always retain the coil even with the weight of a pump on it. Because of the flexibility and coil, the wire gets beat up quicker. When you pull out poly it gets laid on the grass, dirt, animal waste and all that stuff ends up in your well. On a new installation it's not really any quicker than running in sch80 PVC and it's tougher to work with.

The one good thing about poly is that it goes back in the hole fast after a pump change.

when using schedule 80 pvc, how are you coupling the lengths together? I have to admit I was very happy to find out that there was Polly down my well because pulling it out and putting it back in made it that much easier. 320 feet, I couldn't imagine pulling that out and dismantling section-by-section or length by length I should say

On stick pipe I can have that out with my hoist truck in under 30 minutes. With no sore arms or back. The pipe simply screws together every 20'.
