NOVA ROTORS s.r.l.

Who we are

Nova rotors was founded in 1990. Nowadays we are a national benchmark in the manufacturing and selling progressing cavity pumps, wobble pumps, flexible impeller pumps and barrel pumps.


Our pumps are distributed throughout the world and applied in different sectors, from waste water treatment plants both civil and industrial, to oenological and the food sector. They satisfying the most varied demands and application needs.
The company which is located at the foot of the Berici hills, is supported by an advanced control system.
This system is able to follow the quality throughout the productive process thanks to a higly qualified staff sensitive to individual client’s needs.
Nova Rotors, certified ISO 9001:2008 and e OHSAS 18001:2007, guarantees an efficient way of working which is evident in the product and in the quality of service in terms of lower costs , punctual delivery and best performances.
More over we can produce pumps with ATEX proof which is required for applications in explosion areas.
The range is characterized by a big choise of models covering a field of capacity up to 420 m3/h and pressures up to 48 bar in order to satisfy different market needs.
The constant development of new models together with the customization and innovation created, testities to the continuous attention nova rotors gives to its customer.

Our values

Nova Rotors specialises in the construction of progressive cavity pumps. This type of pump is highly flexible in terms of operation and application, a factor which has enabled it to achieve considerable market success. Its unique features makes it suitable for use in a variety of different industries.
The main features of this type of pump are:
 Uniform flow proportional to the speed.
 Self-priming with a maximum suction lift capacity up to 8 mWC (NPSH), depending on the size, the number of stages and pump speed.
 Capacity to pump heterogeneous products, containing gases, solid, abrasive and fibrous materials in the liquid matrix.
 Pumping of liquids with low or high viscosity.
 Liquid dosing capacity.
 Pulse-free pumping with minimum tensile strain of the product being processed.
 High pumping pressure (6 bar per stage). Pumps are available with one to eight stages, depending on the required pressure.
The progressive cavity pump is a volumetric, self-priming, rotary positive displacement device. The “pumping” part consists of two elements, the rotor and the stator. The rotor, typically metallic, is single or multiple screw with a rounded thread, extremely large pitch, considerable length and high eccentricity in relation to the core diameter.
The stator, typically elastomeric, is embedded with a cavity in the shape of a 2 or multiple screws, double threaded, compared to the rotor, and with the same eccentricity.
The rotor, rotating within the stator, is forced to perform a hypocycloid roto-translational movement. This coupling of the two elements always creates a line of contact along the profile that guarantees the seal between them. This movement creates an airtight chamber that shifts with a helical movement, from the suction casing to the delivery casing.
The Diamond series features a patented universal pin joint that ensures top performance and unprecedented flexibility of use. The standardization throughout the entire range of products achieved with this joint has resulted in optimal spare parts management as well as simplified and economical maintenance, without sacrificing reliability and long life.
