Apparatus, including a vertical double-suction pump, is provided featuring a pump casing and a double suction impeller arranged therein on a shaft. The pump casing has a pump casing wall. The double suction impeller has upper and lower shrouds with metal rims configured to form upper and lower isolating annuli between the double suction impeller and the wall of the pump casing in order to impede a recirculation flow from an impeller discharge to be able to act of the upper and lower shrouds and create a controlled axial thrust load from differentiated hydraulic pressure on the upper and lower shrouds. The upper and lower isolating annuli may also be geometrically varied between the upper and lower shrouds of the double suction impeller to create a pressure differential in a direction parallel to an axis of rotation of the double suction impeller.

A shock absorbing apparatus (200) includes a flexible membrane (204) defining an accumulator cavity, and a compression assembly defining a compression cavity. The compression assembly is disposed within the flexible membrane (204) such that viscous fluid contained within the cavities may be exchanged therebetween by a damping orifice (238), fluid conduit and or valve mechanism. The accumulator cavity deforms in response to the application of a transmitted impact load, and is capable of storing and releasing potential energy in response to the application and cessation of the transmitted impact load.

A crimp contact (100) is provided where the axes of the contact form a non-linear angle, such as a 90° angle. The crimp contact (100) can be a multi-part contact with a front contact portion (130) that is attached in a removable or fixed manner to the rear crimp contact portion (130). Optionally, the front contact portion (330) can be attached to the rear crimp contact portion (310) using a threaded connector to form a threaded attachment.

A flexible, pressure-balanced cable assembly is provided. The cable assembly comprises a tubular-shaped flexible outer sleeve (114) that surrounds an electrical cable (105). A plurality of seals (116) is positioned along the length of the flexible sleeve (114) within the space formed between the inner surface of the flexible sleeve (114) and the outer surface of the electrical cable (105). The seals (116) partition the space into a plurality of individual chambers (119). Each chamber is filled with dielectric fluid. The seals (116) are independently and bi-directionally movable in response to a pressure difference between the inside of the cable assembly and the external environment thereby balancing the pressure between the inside of the cable assembly and the external environment.

An electrical-connection system (10) for connecting a first cable to a second cable includes a central connector unit (12) that attaches to cable-end connectors (30, 38). Among other features, the central connector unit (12) includes a curved surface (27), each of the cable-end connectors (30, 38) include a grip mechanism (36). Generally, the electrical-connection system (10) is configured to be positioned in a radial groove of a cylindrical body, such that an overall height of the system is maintained within space constraints.
