1. How do I interpret the VG series pump model code?
The model code indicates the specifications. For example, in "VG1-63REW-A1": "VG1" is the series, "63" is the displacement (ml/r), "R" indicates right-hand clockwise rotation, "E" stands for a straight key shaft, "W" represents NBR (Buna) sealing material, and "A1" is the design number.
2. What sealing materials are available for VG series pumps?
We offer two main sealing options: "W" for NBR (Buna) seals and "V" for FKM (Viton) seals, allowing compatibility with different fluids and operating temperatures.
3. What are the maximum pressure ratings for the VGH0 and VG0 series?
The VGH0 series has a rated pressure of 33 MPa and a maximum pressure of 40 MPa. The VG0 series (displacements 8 to 16 ml/r) has a rated pressure of 31.5 MPa and a maximum pressure of 35 MPa, while displacements 20 to 28 ml/r are rated at 25 MPa with a maximum of 30 MPa.
4. What shaft options can I choose from?
Depending on the series, we offer "K" (straight key shaft for VGH0), "E" (straight key shaft for VG0, VG1, and VG2), and "R" (SAE Spline shaft for VG0, VG1, and VG2).
5. What rotation configurations are available?
Rotation is determined when viewed from the shaft end of the pump. You can choose "R" for Right-hand (clockwise) rotation or "L" for Left-hand (counter-clockwise) rotation.
6. How do I choose the correct flange size for the oil ports?
Each pump specification matches a standardized flange code. For example, the VG0-08 uses an F06 flange for the inlet (S) and an F04 flange for the outlet (P). Detailed flange parameters are listed under the "Single Pump Inlet & Outlet Port Connection Size" table.
