Danfoss M46 Pump Parts

The hydraulic pump is the power component of the hydraulic system, which is driven by the engine or motor, sucks oil from the hydraulic oil tank, forms a pressure oil discharge, and sends it to the actuator. There are many types of hydraulic pumps, among which the elephant hydraulic products M46 series is designed for medium power applications with a maximum load pressure of 345 bar (5000 psi). This series can be combined with other products to form a system to transfer and control hydraulic energy. The M46 series is capable of continuously variable speed from zero to maximum speed in both forward and reverse operation modes. The M46 pump is a compact high power density element. All models use a parallel axial plunger/slipper design concept combined with a tilting swash plate to vary pump displacement. The M46 system may contain an integrated fuel pump to supply the system with hydraulic, cooling, and servo control fluids. The M46 pump is available with a series of auxiliary mounting measures for attaching auxiliary hydraulic pumps.

The M46 pump is available in manual, hydraulic or electrical drive mode with proportional control. Electrically controlled three position control is also available.

The pump receives fluid directly from the reservoir through the inlet line. A screen placed in the inlet protects the pump from large contaminants. The output of the pump is directed to a PVG-32 multi-section load sensing directional control valve which directs fluid to the actuators in the system. Fluid returning from the system is cooled by a heat exchanger and cleaned by a filter before returning to the reservoir. The speed of the actuators in the system depends on the volume of fluid being provided by the pump. The operating pressure varies depending on actuator load, but is limited to an adjustable maximum setting by the PC section of the pump control and by a system relief valve integrated into the side module of the PVG valve. The position of the PVG valve sets the demand for flow in the system and communicates this to the pump control by means of a hydraulic signal (load sense signal). The pump will provide as much flow to the system as it demands Therefore flow and pressure in the system are compensated to meet requirements.
