Series 40 pumps are compact, high power density hydraulic components. The design concept utilizes a parallel arrangement of axial plungers and slide shoes and a tiltable swash plate to change the plunger stroke and thus pump displacement.

The displacement of the pump is changed by changing the stroke of the plunger through a tiltable swash plate. The direction of the pump outlet fluid changes with the direction of the swash plate, thus realizing the motor

The direction of the pump outlet fluid changes with the direction of the swashplate, thus switching the motor output shaft forward/reverse.

Integrated charge pumps on Series 40 - M35, M44, and M46 pumps provide the system with supplemental hydraulic fluid, cooling fluid, and pressure oil for M46 pump control.

The M25 pump can accept hydraulic oil from the auxiliary circuit or from a gear pump output in series with the pump's auxiliary mounting flange.

The M25 pump accepts hydraulic fluid from an auxiliary circuit or from a gear pump mounted in series on the pump's auxiliary mounting flange.

Series 40 pumps are available with a series of optional auxiliary mounting flanges on the rear cover to meet the requirements of the application.

Series 40-M46 pumps are available with manual, hydraulic and electrically actuated proportional displacement controls, as well as electrically actuated three-position (forward-neutral-reverse) controls.

forward-neutral-reverse). M25, M35, and M44 pumps are available with direct displacement control on trunnion type only.

The Series 40 motor concept also utilizes a parallel arrangement of axial pistons/slip shoes with fixed or variable swash plates. Fixed

Fixed displacement motors include M25, M35, M44 and variable displacement motors include M35, M44, M46.

The M35 and M44 variable motors have swash plates with trunnion outputs for direct displacement control by rotating the trunnions.

The M46 variable motors have a tiltable swashplate, and the motors are hydraulically controllable with two variable positions.
