Pitless Unit

What is the difference between a “Normal” vs. a “Flowing" Well spool used in industrial pitless adapter units?

What is the difference between a “Normal” vs. a “Flowing" Well spool used in industrial pitless adapter units?

Since 2018, Boshart has offered two spool types designed to meet the specific needs for each well installation type thus providing greater flexibility and ease of installation!

Normal Well Spools

Normal Well spool designs allows for the LARGEST possible MOON shaped through passages.

The benefits of Normal Well spools are:

❶ Allows for the installation of heavy PVC jacketed pump cable to be inserted through the spool WITHOUT the need to remove the protective jacket.

❷ Provides more room for larger diameter equipment, such as depth probes, etc., to be inserted through the spool.

❸ Allows for multiple PVC probe tubes to be inserted right through the spool. This eliminates the need to thread through the top and bottom of the spool.

Flowing Well Spools

Flowing Well spools provide MORE & LARGER through passage tappings on 8”, 10”, and 12” spools.

The benefits of flowing well spools are:

❶ Ability to seal level monitoring or other accessory cables which allows for more installation capabilities and options.

❷ Ability to insert an inspection camera.

❸ Allows for multiple PVC probe tubes to be inserted into the bottom of the spool without the need to have custom threading on the bottom plate.

Cable Seals

Cable seals are threaded into the top plate of the spool. The submersible pump cable is then inserted through the cable seals as a single conductor.

Cable seals are used in over flowing well applications and provide a water tight seal on the through passages to prevent water from entering the upper barrel chamber. They can also be used as cable restraints. 8" x 10" units require five 3/4" MPT cable seals. 10" x 12" units require five 1” MPT cable seals. 12" x 14" units require five 1" MPT cable seals. The cable diameters will be required in order to supply the proper seal. Pitless spools are tapped to accommodate cable seals as standard equipment – it is not a costly, special order feature.
