NP-52M

NP-52M System Overview

The NP-52M is an axial piston high-pressure hydraulic pump designed for operation in ground-based hydraulic systems used for testing and servicing aircraft equipment. The unit belongs to the class of rotary plunger pumps used in precision hydraulic installations.

NP-52M Control Function

The pump provides generation and regulation of hydraulic pressure within the system, supporting adjustable output characteristics and enabling operation in both flow and zero-delivery modes depending on system requirements.

NP-52M Application

The unit is used in ground hydraulic installations such as UPG-300, PGU-200/260, and similar test benches applied for verification and maintenance of aircraft hydraulic systems.

NP-52M System Integration

The pump is integrated into hydraulic stands and supports both local and remote control of operating parameters, allowing adjustment of pressure and delivery characteristics during operation. The product is also known under alternative designations NP-52M, НП-52М, including modifications NP-52M-2, NP-52M-2T, and NP-52M-3.
