Product details

JR‑R‑S75C‑PC‑20‑NN Danfoss Pump

Product Overview

JR‑R‑S75C‑PC‑20‑NN Danfoss Pump is a heavy‑duty variable‑displacement Hydraulic piston pump from Danfoss 45‑Series open‑circuit design . As the core power‑supply hydraulic pump, it delivers high‑pressure hydraulic oil for the hydraulic system of mobile engineering Machine. This Hydraulic piston pump adopts pressure‑compensated (PC) control, featuring stable output performance, high efficiency and good load‑adaptability. It is widely used in construction, mining and agricultural Machine, acting as main power source for the whole hydraulic system.

Technical Specifications

Working Principle

Driven by the engine of the Machine, this hydraulic pump converts mechanical energy into hydraulic energy. The PC pressure‑compensated control adjusts swash‑plate angle dynamically according to system load, to match flow demand of the hydraulic system. The variable displacement design realizes energy‑saving operation, providing stable high‑pressure oil for actuators of the Machine.

Core Advantages

1. Genuine Danfoss 45‑series Hydraulic piston pump, robust for heavy‑load working conditions .

2. PC pressure‑compensated control, good load‑following performance for the hydraulic system.

3. High volumetric efficiency, low noise and long service life for mobile Machine.

4. Compact structure, high power density, easy installation and maintenance.

5. Perfect matching for off‑highway equipment, reliable replacement spare part for original hydraulic pump.

Application Range

This hydraulic pump is widely applied to construction Machine, mining equipment, road rollers, agricultural machinery and special‑purpose vehicles. It serves as the main power unit of the hydraulic system, driving travel, lifting and auxiliary working functions.
