Vianova builds compact hydraulic power units for mobile machinery and fixed installations. Made to measure, in batches of fifty, with the drawing approved before any metal is cut.
The power unit Vianova builds most often: a twenty-litre tank, two hundred and fifty bar maximum pressure and a four-kilowatt motor. It fits in a half-metre bay and weighs about as much as two bags of cement.
The design is approved and dimensioned before any metal is touched. Changes are made in the drawing office, where they cost little, not on the shop floor.
Every unit runs on the test bench for twenty minutes at rated pressure. The numbered test certificate ships with the unit.
Seals, cartridges and pumps stay in stock for ten years after delivery of the last batch.

Three applications where the same unit has been fitted for years, with the changes each one required.
Larger tank and an added heat exchanger: the unit runs at forty degrees ambient without stopping.
Dedicated valve block and soft start, so the die never takes a pressure spike.
Quick couplings to the manufacturer’s drawing and paint in the manufacturer’s colour, in batches of fifty.
Send the available space and the pressure required: the technical office replies with a dimensioned drawing and a price, with no obligation.
