Hydraulics Online - Supplying you with Vivolo (Vivoil) Hydraulics and Vivolo (Vivoil) Hydraulic Gear Pumps, Gear Motors, Geared Flow Dividers and other Vivolo (Vivoil) Hydraulic Equipment and Components 

Vivoil Oleodinamica Vivolo was founded in 1985 and since then has been producing high performance, high quality hydraulic gear pumps, hydraulic gear motors and geared flow dividers. 

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. 

	XV-0P Series The main features of the XV-0P (European Group 0.5) series are: Displacements from 0.16 to 2.28 cubic centimetres per revolution Maximum pressures up to 280 bar Rotation speeds up to 9000 rpm Configurations with inlet and outlet in the body, flange and cover Cylindrical with woodruff key, milled shank or tapered 1:8 woodruff key shafts.
	XV-1P Series The main features of the XV-1P (European Group 1) series are:   Displacements from 0.91 to 9.88 cubic centimetres per revolution Maximum pressures up to 300 bar Rotation speeds up to 6000 rpm Configurations with inlet and outlet in the body, flange and cover Tapered 1:8 woodruff key, parallel with key, milled shank or splined shafts
	XV-2P Series The main features of the XV-2P (European Group 2) series are:  Displacements from 4.2 to 39.6 cubic centimetres per revolution Maximum pressures up to 300 bar Rotation speeds up to 3500 rpm Configurations with inlet and outlet in teh body, flange and cover Tapered 1:8 woodruff key, parallel with key, milled shank or splined shafts
	XV-3P Series The main features of the XV-3P (European Group 3) series are:  Displacements from 14.89 to 86.87 cubic centimetres per revolution Maximum pressures up to 320 bar Rotation speeds up to 3000 rpm Tapered 1:8 woodruff key, parallel with key or splined shafts

  

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
