Reversible pumps (VIVOIL)
Reversible hydraulic pumps in aluminium, and with external gears. Some pumps in this category are also available with cast iron flanges.
They are used for some special applications, and their rotation verse is alternately clockwise and counterclockwise. Therefore, if you are looking for a pump with clockwise or counterclockwise rotation verse to be reversed according to your needs, we recommend our unidirectional hydraulic pumps, whose rotation verse can be changed without adding any components.
The displacement of the reversible pumps varies between 0.16 cm3/rev and 86.87 cm3/rev, the rotation speed reaches up to 9000 rpm, the maximum pressures reach 320 bar.
Depending on the type, our reversible pumps can have:
- Integrated outboard bearings
- High-Pressure shaft seal
