Hydraulic pumps of NPA type (analogues SPV, GR) are designed for installation in hydraulic systems,
agricultural, construction, road and municipal machines. The product provides conversion of mechanical energy of input shaft rotation into energy of working fluid flow.
The direction and magnitude of the working fluid flow is linearly set by both
direction and the value of deflection of the control lever of the servohydraulic control mechanism. The pressure in the control and make-up lines, as well as the filling of leaks, is provided by an auxiliary make-up pump.
