摘要： A centrifugal pump of the pitot type is structured with axially-arranged inlet and discharge features positioned on opposing axial sides of a rotor, the rotor being journalled between a rotating sleeve and a suction inlet, and the rotating sleeve being concentric with the discharge, the rotating sleeve being gear-driven by a drive mechanism.

摘要： A centrifugal pump of the chopper type is disclosed which is structured with a chopper plate and impeller that are configured with an open eye or “hubless” arrangement such that processing of solids through the pump does not result in clogging of solids at or near the center of the impeller, thereby producing a dead zone. Because the configuration of the chopper pump of the present invention avoids the development of a central dead zone or clogging of solids, and provides for flow of solids and fluid through the eye of the impeller, pump efficiencies are markedly improved.

摘要： Methods of producing impeller castings from very hard materials are disclosed in which the formation of a selectively configured core produces an impeller casting that does not need to be machined to receive the drive shaft and eliminates the need for employing a lead babbitt or soft insert, as is known in the prior art, to receive the drive shaft, thereby producing a hard material impeller for a centrifugal pump that is significantly less costly to produce and is environmentally safe.

摘要： An insert is provided for attachment to the inlet or nose of a pitot tube to withstand the wear and damage imposed on the inlet of the pitot tube by high velocity and high pressure fluid moving through the rotary casing and into the pitot tube. The insert reduces the amount of damage normally done to the pitot tube under normal operating conditions thereby extending the life of the pitot tube. When worn or damaged, only the insert needs to be replaced rather than the entire pitot tube as is done in conventional systems. The insert permits the machining of the insert to meet the specifications of a particular application, thereby providing the ability to control pump performance over a wider range of operational conditions.
摘要翻译： 提供了用于附接到皮托管的入口或鼻子的插入件，以承受通过旋转壳体移动到皮托管中的高速和高压流体施加在皮托管的入口上的磨损和损伤。 插入物减少了在正常操作条件下通常对皮托管进行的损坏的量，从而延长皮托管的寿命。 当磨损或损坏时，只需要更换插入件，而不必像常规系统那样更换整个皮托管。 插入件允许加工插入件以满足特定应用的规格，从而提供在更宽范围的操作条件下控制泵性能的能力。

摘要： A precast prerotation basin system for use in a wet well for removing water or fluid therefrom is disclosed which comprises a prefabricated, three-dimensional body having a prerotation basin and fluid entrance channel. The precast prerotation basin presents an improvement over prior methods of forming prerotation basins downhole in a wet well because the basin system of the present invention is prefabricated, easily transportable and can be placed in a wet well without the need for providing a cement casing or floor beforehand. The precast prerotation basin of the present invention is pre-structured for accurate alignment of a centrifugal pump therein and eliminates the cost and inaccuracies of forming prerotation basins from molding cement downhole.

摘要： A pump impeller for use in industrial pumps of the centrifugal type is disclosed in which the vanes of the pump impeller are particularly configured to maintain pumping efficiency as the vane wears over continuous use or operation of the pump. The impeller vane is configured to continuously present an aggressive cutting surface at the leading edge of the vane even though the vane may become degraded and worn through continuous use.

摘要： In a centrifugal pump of the pitot tube type, a replaceable wear ring is positioned in the rotating assembly of the pump in that area of the rotating case which is most subject to erosion from the processing of abrasive fluids by the pitot tube pump. The replaceable wear ring can be easily and quickly replaced when eroded, thereby eliminating the need to replace the rotating case of the pump and eliminating the need for costly and time-consuming re-balancing of the pump.
