Founded in 1932, VARISCO establishes an international reputation for the design and production of high-quality pumps for fluid transport in the industrial sector, purification and management for abrasive fluids and those with suspended solids.
Varisco specializes in the construction of:
- self-priming centrifugal pumps with semi-open impellers
- positive displacement pumps – especially with internal gear – for high viscosity fluids.
- Fire prevention pumping units in accordance with EN 12845 in various installations.
The success achieved in a highly competitive market is the result of great teamwork, through synergies between internal skills and experience in the field.
The factory is located in Padua (Italy), where the pumps are designed and tested at the internal Research and Development Center.
Internal gear pumps – V range
Internal gear pumps are positive displacement pumps and are used in applications where it is necessary to handle clean fluids with high viscosities.
They are used in all industrial applications where delicate treatment of the pumped product is required, preventing chemical-physical alterations.
