THIS WELL HEAD FITS CASING PIPES WITH A DIAMETER FROM 110 mm TO 130 mm.The well head facilitates both the initial installation operation and subsequent operations of removing and lowering the pump into the well. The well head with the base part is attached to the casing pipe once for the entire period of operation of the well head. In turn, a removable cover is installed on the base part, through which the electric cable and pressure pipe pass. The cover also has a carabiner for attaching the cable.The base part consists of a base installed on the end of the casing pipe, a clamping flange, and a rubber ring. The base part is fixed on the casing pipe by compressing the rubber ring with screws. The base has a terminal box. a threaded sealed cover that closes. The box has sealed cable entries for the supply mains cable and the pump electric cable. A screw terminal block is fixed in the box.Advantages of a sealed well head with a terminal box:- protection of the well from foreign objects and atmospheric precipitation entering inside; - reduces the likelihood of theft of the pump and equipment from the well;- increases the reliability of pump suspension;- significantly simplifies the installation of the well head due to the absence of welding
