These alphanumeric designations often correspond to specific displacement ranges, pressure ratings, and mounting configurations. For instance, the A2FM series and A4FO series represent distinct families of axial piston pumps, while the B1-300 and 25SCY14-1B models indicate specialized variants often associated with high-pressure applications.

The technical attributes of these pumps are critical for matching the component to the intended hydraulic system. The observed product data highlights that these units are fundamentally classified as "Plunger Pump" or "Plunger Type" devices, operating on the principle of converting mechanical energy into hydraulic energy through reciprocating pistons. A key specification to verify is the power rating, with some units observed to have a power rating of 1500W, though this varies significantly by model. The excitation mode is noted as "Excited," and the speed classification is generally "High Speed," which necessitates robust bearing systems and precise machining tolerances.

Furthermore, the physical configuration of the pump is essential for integration. The motor flange shape is observed to be available in "Square and Rhombus Flange" configurations, while motor shafts may come in "Straight, Splined and Tapered" varieties. Buyers must ensure that the selected model's shaft type and flange geometry align perfectly with the hydraulic motor or actuator it will drive. The casing protection type is another critical observation, as the environment in which the pump operates dictates the necessary ingress protection levels. The product origin is consistently listed as "China," and the standard condition is "New," with specific listings confirming "100% New" status. Understanding these specific model identifiers and their associated physical attributes is the first step in defining a precise procurement requirement.

Compliance, Certification, and Quality Standards

In the global procurement of hydraulic components, verifying compliance with international standards and certifications is non-negotiable for ensuring safety and reliability. The observed market data indicates that suppliers for these axial plunger pumps often provide certifications such as CE, ISOCE, RoHS, and GS.
