摘要

A replaceable motor module for a groundwater sampling device including an inner housing defined by a cylindrical shape and having a first alignment pin. A DC-operated electric motor is positionable within the inner housing, and includes a first set of electrical input terminals, an output shaft capable of downwardly extending through a sealed hole in the inner housing, and a first alignment groove for mating with the first alignment pin of the inner housing. An inner housing cap includes a second set of electrical input terminals and electrical output terminals, and is pressingly engageable with the inner housing.
