Unidirectional pumps (VIVOIL)
Unidirectional hydraulic pumps in aluminium, and with external gears.
Some pumps in this category are also available with cast iron flanges.
The rotation verse is clockwise or counterclockwise, and you can reverse it without adding any components, so you can optimize storage space and adapt the pump to your needs.
The displacement of these products varies between 0.16 cm3/rev and 86.87 cm3/rev, the rotation speed reaches up to 9000 rpm and the maximum pressures reach 320 bar.
Depending on the type, our unidirectional hydraulic pumps can have:
- Integrated outboard bearings
- Anti-cavitation valve
- Maximum pressure relief valves
- Priority valves
- Bypass electric valves
- High-Pressure shaft seal
