Abstract
A centrifugal pump has a housing with intake and discharge fittings at axially opposite ends. The electronic motor is supported on ribs within the pump housing and the motor casing is closed by the electronic control circuit for the motor which seals the motor against the pump liquid. The coolant thus flows around the electric motor and its control circuit.
