EMS A1650 pitless adapter 1", brass, DN25

E.M.S. A1650 1" Brass Borehole Adapter, DN25

E.M.S. A1650 is a brass borehole adapter designed to provide a simple and sealed water connection through the well casing. It allows the discharge pipe from a submersible pump to pass through the side of the casing while helping prevent dirty surface water from entering the well.

The adapter consists of two sections that slide into each other and are sealed by an O-ring. This construction allows the submersible pump to be lifted without unscrewing pipe couplings. A lifting pipe can be attached to the upper section to simplify installation and removal.

For article A1650, E.M.S. officially specifies a 1" brass adapter.
