Abstract

A submersible motor-driven pump includes a housing having an intake connection and a discharge connection; an impeller mounted in the housing between the intake connection and the discharge connection; and a shaft on which the impeller is mounted, the shaft being supported for rotation in the housing. The shaft extends concentrically into a cylindrical can mounted in the housing form a free space between the shaft and the can. Anti-freeze apparatus is installed in the housing for protecting the shaft.
