Eaton Accumulators - Bladder, Diaphragm & Piston Type
The shells of bladder and piston type accumulators are manufactured from a homogeneous, seamless tubing. In bladder accumulators one or both ends is formed hemispherically by either spinning or hammering operations. Strict heat treatment and stress relieving is performed on all shells after the forging operation to ensure compliance with the required mechanical properties.
A full range of bladders have been developed from the most advanced elastomers capable of meeting low temperatures (down to -45 F) and high temperatures (up to 400 F). These same bladder materials are compatible with most fluids.
A computer program enables calculation of the gas permeation level of different elastomers. This allows us to recommend a bladder material and set up a pre-charge maintenance program which is suited to our customers needs.
The fluid port incorporates a poppet valve which prevents the extrusion of the bladder. Special care has been taken in the design of the fluid port assembly to prevent turbulent flow, pressure drop, and potential preclosure of the poppet valve. A heavy duty spring prevents premature closure of the poppet valve.
The design of the bladder accumulator makes use of the considerable difference in compressibility between a gas and fluid. The bladder contained in the shell is precharged with nitrogen gas to a pressure determined by the work to be done.

Eaton Power Units
Integrated Motor Pumps, models MP15, MP22, MP45, MP75 & MP92 are are all 15 kW, 20 hp to 92 kW, 125 hp.
The Vickers Integrated Motor Pump is a unique combination of a conventional AC induction motor cooled with system hydraulic oil and a Vickers hydraulic pump, either fixed vane pump or variable piston type, housed in a special sound reduction enclosure.
This combination provides an exceptionally quiet and small pumping package for any industrial application requiring up to 125 horsepower (92 kilowatts) of continuous hydraulic power. The package comes completely assembled, tested, and ready for installation.
Circulating the hydraulic oil through the motor, bathing both the rotor and stator, makes it possible to obtain twice the normal continuous output power from the motor windings. Physical size reductions of 35% to 50% compared with conventional pumping packages are possible as a result. Normal operation of the motor is not affected by circulating oil through it, nor is the system’s hydraulic oil damaged.
Heat generated within the electric motor is carried away by the hydraulic fluid and dissipated by the hydraulic cooling system. A motor fan is not needed, which makes it practical to cover the entire assembly (motor and pump) with a compact, polyethylene sound reduction enclosure. This reduces the sound from the pump as well as the motor, resulting in a noise level reduction that is nsurpassed in the industry.
A complete line of standard Vickers pumps can be fitted to the Integrated Motor Pump including single fixed vane pumps, single ariable piston pumps, double vane pumps, double piston pumps or mixed vane and piston combinations.
