Abstract: A hydraulic jet pump comprising: a nozzle housing; a nozzle member disposed within said nozzle housing and including an inlet aperture communicating through a jet nozzle with a mixing chamber along a power fluid inlet flow path; a deflector member including an axial bore formed partially therethrough from an input aperture at a first end thereof towards a second end thereof, said input aperture communicating with said mixing chamber, said deflector member further including a plurality of radially-disposed deflector outlet ports communicating with said axial bore and disposed at an acute angle with respect to said input aperture to form a flow path having an output flow direction disposed at an acute angle with respect to an input flow direction from said input aperture, said deflector member further including a plurality of axially-aligned vacuum inlet ports formed therethrough from said first end to said second end and in communication with said mixing chamber but not with said deflector outlet ports.

Abstract: A tube end formed of any suitable material having the shape of a truncated cylinder that is forced over the end of a polyethylene pipe and prior or post heat-treated to provide a THERMO LOCK-N-SEAL.TM. interface between the OD of the polyethylene pipe and the ID of the tube end by melting a portion of the OD of the polyethylene tube sufficient to cause thermal plastic flow of the polyethylene into conformity with the surface of the ID of the tube end.
