Frequently Asked Questions
What does the model code "VG1-63REW-A1" stand for?
According to the model representation, "VG1-63REW-A1" stands for the VG1 Series pump with a displacement of 63 ml/r, right-hand rotation (clockwise, viewed from the shaft end), a straight key shaft (E), NBR sealing material (W), and design number A1.
What sealing material options are available for the VG series pump?
The VG series single pumps support two sealing materials: W (Buna NBR) and V (Viton FKM), allowing compatibility with different operating temperatures and hydraulic fluids.
What is the maximum speed limit for the VGH0, VG0, VG1, and VG2 pumps?
The VGH0 series pump has a maximum speed of 4200 r/min. The VG0, VG1, and VG2 series pumps have a maximum speed limit of 3000 r/min.
How is the rotation direction of the pump determined?
The rotation direction is viewed from the shaft end of the pump. "R" designates right-hand (clockwise) rotation, while "L" designates left-hand (counter-clockwise) rotation.
What are the rated and maximum pressure specifications for the VG series?
The rated pressure for VGH0 is 33 MPa (max pressure 40 MPa). For the VG0, VG1, and VG2 series, the rated pressure is generally 31.5 MPa (max pressure 35 MPa), except for specific displacement models like VG0-20/25/28, VG1-63, and VG2-145/160, which operate at lower pressure ranges.
