摘要： A sealing ring provides a fluid seal between a first flange and a second flange. The sealing ring forms a tubular element and includes a tapering wall member defining an interior funnel-shaped through-going opening extending axially and tapering from a proximal end to a distal end. The tapering wall member is made from a resilient material proving an axial deflection of the tapering wall member when exposed to an axial force.

摘要： The invention relates to a side-channel pump and to a method for operating a side-channel pump in which an impeller rotates in a working chamber provided with a side channel. According to the invention, the pump is operated at an overspeed with a gas-filled working chamber in a first step. The speed is then reduced to an operating speed in order to pump a liquid. The pump according to the invention has a high suction power as a result of the overspeed, but only gas is drawn initially.

摘要： A submersible well pump assembly has a pump and an electrical motor for driving the pump. The motor has an electrical receptacle with a base and a central bore containing a plurality of motor electrical terminals. An annular groove in the base encircles the central bore and has a closed bottom. A motor lead extends to the motor for supplying power to the motor. An electrical connector on an end of the motor lead has a rim that inserts into the groove. Either the forward edge of the rim or the bottom of the groove is conical, defining an annular void within the groove that is triangular in cross section when the rim is fully inserted into the groove. A seal ring is located in the void of the groove and is deformed by the forward edge of the rim into sealing engagement.

摘要： A coupling pin for use in a pump housing, the pump housing including an outer casing and an inner pump liner, the coupling pin being suitable for locating the liner and casing relative to one another, the coupling pin including a shank and a head at one end of the shank. The head includes a cammed surface thereon which is adapted to co-operate with a follower on the liner, and a locating section on a remote or terminal end of the head which is adapted to be positioned against a seat in the outer casing when fitted. The arrangement is such that rotation of the coupling pin causes the follower to track along the cammed surface so as to cause relative movement between the outer casing and the inner pump liner.
