Danfoss 90R180 HS5NN80TCC8 H03 NNN323224 Hydraulic Axial Piston Pump
Overview
The Danfoss 90R180 HS5NN80TCC8 H03 NNN323224 is a high-performance axial piston variable displacement pump from Danfoss‘s renowned Series 90 family (90R Series)--1. Designed for closed-circuit hydrostatic transmissions, this pump features a cradle swashplate design that enables variable displacement control, making it a versatile and powerful solution for demanding mobile and industrial hydraulic systems-. With a maximum displacement of 180 cc/rev and a pressure rating of up to 400 bar (5,800 psi), the 90R180 delivers exceptional power density and reliability for heavy-duty applications--1.
Technical Features
Axial Piston, Variable Displacement Design – The pump utilizes a parallel axial piston/slipper concept with a tiltable swashplate (cradle design) to vary displacement steplessly-. This design enables precise flow control and high overall efficiency.
High Pressure Capability – The pump is rated for a maximum operating pressure of up to 400 bar (5,800 psi), with some specifications indicating a maximum pressure of 450 bar (6,525 psi) for the S90R180 variant--1. This high pressure capability makes it suitable for the most demanding hydraulic systems.
Large Displacement – The pump has a maximum displacement of 180 cc/rev (180 cm³ per revolution), providing substantial flow for high-power applications--1-6.
High Speed Capability – The pump can operate at speeds up to 4,000 rpm, enabling high flow output and fast system response-1-6.
Clockwise Rotation – The pump is designed for clockwise rotation when viewed from the shaft end, ensuring proper integration into hydraulic systems-1-6.
Robust Construction – Built with a ductile iron housing and a high-strength steel shaft, the pump is engineered for long service life and reliable operation in harsh environments-1-6. Heavy-duty bearings provide high load capacity-1-6.
NPT Ports – The pump is equipped with NPT (National Pipe Thread) ports for easy integration with standard hydraulic fittings in North American and other markets-1-6.
Flange Mounting – The pump features a flange mounting type, providing a secure and stable installation-1-6.
Standard Nitrile Seals – The pump uses standard nitrile seals for compatibility with a wide range of hydraulic fluids-1-6.
Compact and Lightweight Design – The pump offers high power density in a compact package, making it easy to integrate into space-constrained systems-1-6.
High Efficiency – The 90R series pumps are designed for high volumetric and mechanical efficiency, providing excellent performance and energy savings--1.
Smooth and Quiet Operation – The pump provides smooth and quiet operation, reducing noise and vibration in the hydraulic system-1-6.
Core Functionalities
Variable Displacement Flow Control – The pump’s displacement can be infinitely varied by adjusting the swashplate angle, providing precise, stepless control over hydraulic flow output-. This allows the pump to match flow precisely to system demand, improving efficiency and reducing energy waste.
Closed-Circuit Hydrostatic Transmission – The pump is specifically designed for closed-circuit (hydrostatic) applications, where fluid is continuously recirculated between the pump and motor in a sealed loop-. This configuration minimizes losses and provides precise power delivery.
High Power Density – The combination of 180 cc/rev displacement and up to 400 bar pressure capability delivers exceptional power output in a relatively compact package-.
Energy Efficient Operation – The variable displacement capability ensures that the pump delivers only the flow required by the system, reducing hydro-mechanical losses, minimizing heat generation, and lowering overall power consumption-1.
Overload Protection – The pump incorporates internal pressure compensation features to protect the system from excess pressure, ensuring safe operation under varying load conditions-1.
High Reliability and Long Service Life – With its robust ductile iron construction, high-strength steel shaft, heavy-duty bearings, and precision engineering, the pump ensures long-term operational stability with minimal maintenance requirements-1-6.
Versatile System Integration – The pump can be configured with various control options (manual, hydraulic, electric) to suit different application requirements-.
