EMS A1645 sealed well cap 110–140 mm

E.M.S. A1645 Well Hat with Electrical Box, 110–140 mm

E.M.S. A1645 is a deep-well protective hat manufactured by E.M.S. International AB, designed to protect the upper section of a deep well while providing an organised solution for the electrical connections of a submersible pump. The manufacturer officially identifies the product as E.M.S. Well hat with electrical box and states that it provides both attractive and functional protection for deep wells. For article A1645, the specified size range is 110–140 mm.

The well hat is manufactured from aluminium, providing a robust construction for installation at the top of the well casing. It covers and protects the upper section of the borehole while simultaneously providing a dedicated location for electrical connections associated with the submersible pump. E.M.S. develops products specifically for deep-water-well applications, and its international website presents products designed for use in deep wells.

The A1645 incorporates an electrical connection box. According to E.M.S., the box is suitable for cables with conductors up to 4 mm², allowing the electrical connections of the pump to be arranged in one accessible location at the well head. This provides a clean and practical installation and simplifies subsequent access to the electrical connections.

The product also includes two strain-relief cable fittings. These fittings mechanically secure the cables and help reduce mechanical stress on the electrical terminals that could otherwise result from pulling or movement of the cables.

For the A1645 specifically, the official E.M.S. product table gives a size range of 110–140 mm. For larger well casings, E.M.S. offers the separate A1646 model for 168–193 mm, so the two versions should not be confused.
