VIVOIL OLEODINAMICA VIVOLO HYDRAULIC GEAR PUMPS:
The design of their XV-P series of hydraulic gear pumps exploits many new and innovative technical and solutions, for which they have been awarded 3 patents. All Vivolo (Vivoil) hydraulic gear pumps can be supplied as hydraulic gear motors, with either single rotation or reversible, with internal or external drains.

VIVOIL OLEODINAMICA VIVOLO HYDRAULIC FLOW DIVIDERS:
Vivoil also produces a comprehensive range of flow dividers, supplied with or without phase correction and integral valves. Vivoil's "RV Series" of "Group 0" and "Group 1" flow dividers comprises:
- RV-D; standard flow divider, simply divides the incoming flow without phase correction
- RV-S; one phase correction valve for all elements. It divides the flow and allows phase correction, but only in the direction of the flow division
- RV-V; flow divider has one phase correction and anticavitation valve for each element, allowing a flow correction in both directions (flow division and flow unification). It can also adjust the relief pressure to a different value for each element.
- RV-G; this is the motorized version of the RV-D divider, with a motor connected to the flow divider elements. This solution is important when the incoming and/or outgoing pressure is below the minimum pressure required to start. Giving flow to the motor helps the flow divider rotation to start.
- RV-H; the motorized version of the RV-S flow divider, with the motor having the same function as described for the RV-G flow divider
- RV-N; the motorized version of the RV-V flow divider, with the motor having the same function as described for the RV-G flow divider
