PV2R3-125-F-RAA-41, PV2R4-136-F-RAA-41 vane pump parameters

The nameplate parameters of the hydraulic vane pumps PV2R3-125-F-RAA-41 and PV2R4-136-F-RAA-41 can be summarized as follows:

1. Vane pump PV2R3-125-F-RAA-41 parameters

① Series number: PV2R3, indicating that the vane hydraulic pump belongs to the PV2R series. The PV2R series vane pump is a high-pressure, high-performance hydraulic oil pump specially developed for low noise.

② Pump displacement: 125 represents the displacement of the vane pump, and the theoretical displacement is 125 cm³/rev.

③ Installation type: F, indicating that the vane pump adopts flange installation method.

④ Rotation direction: R, indicating that the pump rotates clockwise when viewed from the shaft end of the oil pump.

⑤ Oil discharge port direction: A, indicating that the oil discharge port is located above the oil pump when viewed from the shaft end (standard position).

⑥ Oil suction port direction: A, indicating that the oil suction port is also located above the oil pump when viewed from the shaft end (standard position).

⑦ Design number: 41, indicating the specific design code of the pump.

2. Parameters of vane pump PV2R4-136-F-RAA-41

① Serial number: PV2R4, which also means that the pump belongs to the PV2R series.

② Pump displacement: Similar to PV2R3-125, “136” represents the displacement code of the pump.

③ Installation type: F, indicating that the pump also adopts flange installation method.

④ Rotation direction: R, indicating that the rotation direction of the pump is also clockwise when viewed from the shaft end of the oil pump.

⑤ Oil discharge port direction: A, indicating that the oil discharge port is located above the oil pump when viewed from the shaft end (standard position).

⑥ Oil suction port direction: A, indicating that the oil suction port is also located above the oil pump when viewed from the shaft end (standard position).

⑦ Design number: 41, the same as PV2R3-125, indicating the specific design number of the pump.

In summary, the main difference between the two vane pumps lies in the serial number (i.e. pump code) and displacement code, while the installation method, rotation direction, discharge and suction port directions, design number and other parameters are the same. These parameters together determine the performance and application scenarios of the vane pump.
