Usage:
The parts chart which follows shows the part numbers for the seals that are used in the Vickers pump cartridge groups which have the steel backed bronze plates between the rotor and the end plates. The part numbers to the right of the part numbers for the cartridge groups are the latest needed to service the new cartridge groups. Follow these recommendations when installing the two lip-style seals shown in Columns G and H.
-
- ... Use the correct tools during installation to prevent damage to the seal case and/or lip.
- ... Install the seals with the lips toward the pump.
- ... Push the inner seal into the housing until it is against the bottom of the bore.
- ... Install the outer seal so it is flush (even) with the face of the housing.
- ... Use the correct tools during installation to prevent damage to the seal case and/or lip.
| NOTICE |

To prevent a leak, both seals must be installed so their cases are in parallel alignment with the bore.

There are fifty-one (51) cartridge groups in the chart and they are in part number sequence. The column to the immediate right of the cartridge group number is a Vickers reference number for the basic pump size. Please note that there are only five (5) basic pump sizes (20V, 25V, 30V, 35V and 45V) and each basic pump size uses the same seals. Also, any cartridge group which has the same Vickers reference number, as shown in the chart, can be used as a replacement for any other cartridge group with the same Vickers reference number. Because of this, be sure to use a cartridge group with the correct rotation and cam ring size.
The third column has the title Cam Ring Size G/P/M (gallon/per/ minute). The numbers shown in this column can be seen on the cam ring in the cartridge group. The fourth column gives the direction of rotation for which cartridge group is designed.
