Axual-piston-piston-piston-adjustable types NGLS112/32 with LS-regulator and pressure regulator are used in volumetric hydraulic drives of machines and assemblies in the regulatory pump modes.
The pump is designed to convert the mechanical energy of rotation of the drive shaft into the variable energy in terms of working fluid flow (in a closed scheme).
The pump is equipped with a Load-Sending (LS) regulator and a pressure regulator made in one case. LS regulator works as a supply regulator depending on the pressure drop on the valve and coordinates the working volume of the pump with consumption in the system.
