sauer danfoss pump identification guide 2024

The present identification manual for Sauer-Danfoss pumps shall now open up a guided walk-through for the identification of Sauer Danfoss pumps; the identification guide shall deal with the reading of electronic data tags, product nomenclature, nameplate data, and general identity guides for Sauer Danfoss pumps.

sauer danfoss pump Nameplate

The nameplate would be the most important on your pump, bearing all the information you might need to know about it. The nameplate is situated at the front of the Sauer Danfoss pump.

The nameplate of a Sauer Danfoss pump provides details on the various parts and its components.

First off, it should be apparent that the nameplate is printed in a variety of languages; this is because our pumps can serve many different countries of the world. The top row is English, and below that is space for additional languages like French, German, Spanish, and Chinese. The barcode scanner is underneath these languages. This will be used by the service technician when changes or diagnoses need to be made to your motor to scan the serial number on your pump. This barcode scanner will also provide any software update or service information needed for your product.

Sauer danfoss Series 45 Pump identification

Series 45 is a whole family of high-performance variable displacement axial piston pumps. Every frame is engineered and built to outperform the high duty cycles of the mobile equipment marketplace. Resultingly, each frame in the Series 45 family will be optimized regarding performance, size, and cost.

High Performance

• Displacements of 25 cm³ – 147 cm³ [1.53 – 8.97 in³/rev]
• Speed of 3600 rpm • Up to 310 bar [4495 psi]
• Wide control system options—room for variety, including load sensing and pressure compensated

New Tools

• Customer focused by means of QFD and DFM techniques
• Maximally optimized design gives the highest efficiency and operation at low noise
• Numerical modeled castings for optimization of the inlet conditions to obtain the highest pump speed possible
• Small package size, minimizing its installation space
• Tapered heavy-duty roller bearings, life span
• The single piece of rigid housing eliminates the paths for noise and leaks
• There will be some speed of response in the integrated controls and system stability

Reliability

• Designed and built with strict standards
• Proven in laboratory and field
• Manufactured with precision quality
• Long life
• Substantially fewer number of parts
• Not a gasketed joint
• The heavy-duty input shaft bearings are capable of taking large external shaft loads
• Gauge points intended for indication of service conditions

Sauer danfoss Series 90 Pump identification

Series 90 hydrostatic pumps and motors can be applied together or combined with other products in a system to transfer and control hydraulic power. They are intended for closed circuit applications.

• Series 90 – advanced technology
• Seven sizes of variable displacement pumps
• Proven reliability and performance
• Compact, lightweight
• Worldwide sales and service
• PLUS+1™ compliant controls and sensors

Series 90 variable displacement pumps are compact, high power density units. All models utilize the parallel axial piston/slipper concept in conjunction with a tiltable swashplate to vary the pump’s displacement. Reversing the angle of the swashplate reverses the flow of oil from the pump and thus reverses the direction of rotation of the motor output.

Series 90 pumps include an integral charge pump to provide system replenishing and cooling oil flow, as well as control fluid flow. They also feature a range of auxiliary mounting pads to accept auxiliary hydraulic pumps for use in complementary hydraulic systems. A complete family of control options is available to suit a variety of control systems (mechanical, hydraulic, electric).

Series 90 motors also use the parallel axial piston/slipper design in conjunction with a fixed or tiltable swashplate. They can intake/discharge fluid through either port; they are bidirectional. They also include an optional loop flushing feature that provides additional cooling and cleaning of fluid in the working loop.

S90 R X XXX XX X XX XX X X XX X XX XXX XX XX XX

Mainly see that the model code on the nameplate starts with S90, then this pump is the Danfoss 90 series pump. Next, we will explain how to identify the specific 90 model.

danfoss Series SNP2|SEP2|SKP2 Pump identification

Sauer-Danfoss high performance gear pumps are fixed displacement pumps which consist of the pump housing, drive gear, driven gear, DU bushings, rear cover and front flange, shaft seal and inner / outer seals, as shown in the section drawing . The pressure balanced design of the pumps provides high efficiency for the entire series.

The standard SNP2 pumps are offered throughout the given range of displacements.There are also two special versions, the SHP 2 and the SKP 2. The SHP uses longer journal bearings to achieve a higher pressure capability in the larger displacements. The SKP is designed to accommodate an SAE 11 tooth splined shaft for higher torque applications.

• Large displacement range (from 4 to 25 cm3)
• High performance at low cost
• Efficient pressure balanced design
• Proven reliability and performance
• Optimum product configurations
• Full range of auxiliary features
