Abstract
A combination pump and heat exchanger assembly uses a cast metal pump case with two upwardly opening sockets receiving the lower ends of two tubes, one of them communicating through the case with the pump impeller intake and the other with the impeller discharge. The tubes are constructed to function as heat exchanger units and are removably secured to the case by threaded fasteners and are sealed therein by compression seals. The heat exchanger tubes may employ electrical heating units or chilled liquid piping units therein.
