ATOS

1. ATOS PFE vane pump are fixed displacement-twelve-vane pump,

2. 2 and 3 cartridge design with integral hydraulic balancing 4 for high pressure operation and long service life with low noise level.

3. Suitable for hydraulic oils according to DIN 51524 OR synthetic fluids have similar lubricating characteristics.

4. These pumps are available as single, multiple or with through-shaft configuration.

5. Mounting according to SAE J744 standard.

6. Easy installation as inlet and outlet ports can be assembled in any of four relative positions.

7. Easy maintains as the pumping cartridge can be replaced in a few minutes.

8. Wide variety of displacements up to 150 cc/rev. Max. pressure 210 bar .
