German Hawei R8.3-8.3-8.3-8.3BABSL piston pump

This is a slanted disc axial plunger fixed displacement pump produced by HAWE, a German company. It has four independent pump units and adopts a through shaft drive structure. It is essentially a 'quadruple pump', driven by an input shaft to four independent pump cores, which can provide pressure oil for different circuits of a hydraulic system.

Model Interpretation (Key Information)

Each part in the model represents a specific technical feature:

1. R8.3：

• R: Representing 'Radialkolben'? A common misconception needs to be corrected here. In HAWE's naming system, the R series usually refers to inclined disc axial piston pumps, rather than radial piston pumps. It belongs to the compact high-pressure pump series.

• 8.3: Represents the nominal displacement of each pump unit, in cubic centimeters per revolution (cm ³/rev). For every revolution of the pump shaft, each unit theoretically discharges 8.3 milliliters of oil.

2. -8.3-8.3-8.3：

• These three repeated "8.3" indicate that this is a quadruple pump, and the displacement of the four pump units is the same. Each "-8.3" represents an independent pump core.

• The structural order is: R8.3 (first pair)+8.3 (second pair)+8.3 (third pair)+8.3 (fourth pair).

3. BABSL：

• This is the code for the connection and installation form, which is the key to understanding the specific configuration of the pump.

• B: Usually refers to the connection form of the pump outlet (pressure oil port), such as a threaded interface that meets certain standards (such as BSPP, SAE, etc.), which needs to be checked in the HAWE sample.

• A: Usually refers to the connection form of the inlet (suction port) of the pump.

• B: The second B usually represents the type of through shaft end (rear drive end). This means that there is an extended shaft at the tail of the pump that can be used to drive a second pump in series (such as a gear pump as a pilot pump or auxiliary pump), forming a pump group.

• SL: Usually represents the direction of rotation of the shaft and the type of shaft. S usually represents that the shaft end complies with the standard (such as DIN or SAE), and L represents that the rotation direction of the shaft is left (counterclockwise when viewed from the shaft end). This is very important installation information.

Main features and advantages

1. Highly integrated: Integrating four independent pumps into one housing, the structure is extremely compact, saving installation space and simplifying system piping.

2. Through axis drive (B): allows for additional pumps to be connected in series at the rear end, expanding system functionality and being very flexible.

3. High pressure performance: HAWE R series plunger pumps are known for their high pressure resistance, with a working pressure of up to 350 bar or higher.

4. Quantitative pump: The displacement is fixed, and the output flow rate is proportional to the driving speed. Suitable for systems that require multiple stable traffic sources.

5. Multiple independent outlets: Four outlets can supply oil to different actuators in the system (such as multiple oil cylinders or motors), or achieve complex actions through valve combinations.

6. High reliability: Made in Germany, renowned in the industrial field for its precision, durability, and long lifespan.

Typical application areas

This type of multi link quantitative pump is commonly used in compact equipment that requires multiple independent or interconnected hydraulic circuits, such as:

• Construction machinery: working devices and steering systems for small excavators, forklifts, and loaders.

• Machine tool: an automated production line or machining center that requires multiple coordinated actions.

• Special vehicles: multiple hydraulic functional mechanisms of sanitation vehicles and cranes.

• Industrial equipment: plastic machinery, die-casting machines, and other equipment with multiple sets of motion requirements.
