Closed Hydraulic MPV

Axial piston pumps with adjustable swash plate series mpv used in hydraulic c closed flow to convert the mechanical energy of the drive motor in the hydraulic energy flow of the liquid (GC). Regulation of feed pump rj ensured the tilt angle of the disc and thus change the course of the pistons, establishing a working volume of the pump. Pumps series mpv with interior adjustment and reversible rj flow is used mainly in hydraulic drive in which the gc from the input of the hydraulic pump. In this series of pumps M4PV, M5PV, M6PV its technical features – high speed, small size, they adapted to install a second axial-piston pump (flow) and make-up gear pumps, easy maintenance, built-in safety and make-up (anti-cavitation) valves. Pumps in this series are fitted with the following types of controls: manual, manual with servo, automatic, electric (12 or 24), hydraulic proportional and electronic. Safety valves in the housing pump can be adjusted to the required opening pressure. Pump design provides the installation of the limiter output, the filter pressure hydraulic load pump and relief valve.

In the pump casing establish an exchange or "wash" with the throttle valve, to protect the heat rj closed-loop circulation flow with a drain hose aj when reversing the flow of aj. Product Series mpv by integrated feed pumps have significant advantages over the axial-piston pumps without charging pump. For example, they can operate with a speed in excess of 1.5 1.65 times the speed of axial-piston pumps without makeup, including cold aj at low ambient temperatures.
