Model MB ST Quick Kit from Maass Midwest offers a pitless unit for commercial, industrial or municipal submersible pump applications. Intended for larger submersibles, the Quick Kit is comprised of three components - a watertight, cast aluminum cap, a spool with o-ring seals and NPT threads and a housing with 304 stainless steel o-ring and spool seats. Only one weld is needed to attach the upper barrel to the housing, and the upper barrel, which is made from standard well casing, can be made for any length bury depth needed. Maass Midwest
