Abstract
A jet pump comprising a pump housing containing a jet nozzle and a throat diffuser nozzle. The jet nozzle is comprised of a jet nozzle insert disposed in an axial inner bore of a precision jet cylindrical body and formed of an ultra-hard material. The throat diffuser nozzle is comprised of a throat diffuser nozzle insert disposed in an axial inner bore of a precision throat diffuser cylindrical body and also formed of an ultra-hard material. The jet nozzle and throat diffuser nozzle are disposed in an elongated cylindrical central bore portion of a tubular side wall of the pump housing. In order to achieve highest concentricity of the axial inner bores, the axial inner bore of the jet nozzle insert and the axial inner bore of the throat diffuser nozzle insert are formed after placement in the precision cylindrical bodies.
