NP-89D / NP89D

NP-89D System Overview

The NP-89D / NP89D is an aircraft high-pressure plunger hydraulic pump with valve-slot distribution designed for supplying working fluid to onboard hydraulic systems. The unit operates as a primary pressure source within aircraft hydraulic architecture.

NP-89D Hydraulic Function

The pump provides generation and automatic regulation of hydraulic pressure and flow depending on system demand. It ensures stable operation of hydraulic circuits while reducing load and overheating through variable displacement control.

NP-89D Aircraft Application

The unit is widely used in hydraulic systems of aircraft, including platforms such as Il-76, where it supplies fluid to actuators responsible for landing gear operation, braking systems, and wing mechanization.

NP-89D System Integration

The pump is driven from the aircraft engine or accessory gearbox and operates in conjunction with onboard hydraulic systems, delivering fluid under high pressure to control and power systems. The product is also known under alternative designations NP-89D, NP-89D-3, and НП-89Д.
