<p>The pump includes a discharge head (H) having a pair of axially spaced end walls defining in part an annular chamber therebetween. The tank (10) includes a housing (42) in communication with a liquid outlet conduit (38). By seating the discharge head in the tank housing, an annular pump discharge chamber (86) is defined with the housing and between the end walls of the pump. Clean coolant from the suction side of a filter (20) disposed in the tank flows through the pump (P) inlet and discharge head into the tank outlet conduit for delivery to machine tools. The pump is driven through a releasable coupling (92) by an electric motor (94) disposed above the tank mounted for movement between operative and out-of-the-way positions whereby the pump may be readily removed from and reinstalled in the tank without disconnection or connection of pipe fittings within the tank.</p> |
