Screw pumps

Nova Rotors, an Italian company and leader since 1990 in the construction of industrial pumps, presents its complete range of helical pumps designed to ensure efficiency and reliability in the most demanding industrial processes. Nova Rotors helical pumps comprise two innovative technologies: the Diamond series single screw pumps, which use a single helical rotor for the progressive cavity principle, and the Raptor series twin screw pumps, which employ two synchronized helical rotors for sanitary applications. Distributed worldwide, these solutions find application in the food, pharmaceutical, chemical, wine-making and water treatment sectors, where delicate and precise fluid handling is fundamental to the quality of the production process. The combination of construction robustness, application versatility and compliance with the most stringent regulations makes Nova Rotors helical pumps the ideal choice for companies seeking durable and high-performance pumping solutions.

Nova Rotors helical pumps are based on advanced technologies that use helical rotors to ensure uniform and continuous fluid transfer, eliminating the pulsations typical of other pumping systems.

Progressive cavity single screw technology

The Diamond series single screw pumps use a helical rotor that rotates inside an elastomeric stator, creating sealed cavities that move progressively along the pump axis. This innovative progressive cavity principle ensures uniform and continuous fluid transfer, eliminating pulsations and ensuring precise flow control for the most demanding industrial applications.

The helical design of the rotor allows effective handling of viscous fluids, products containing solid particles, abrasive substances and temperature-sensitive liquids, making these helical pumps particularly versatile for various industrial sectors.

Synchronized twin screw technology

The Raptor twin screw pumps of the HTS series represent the evolution of helical pumps for sanitary applications. They use a system with two synchronized helical rotors that rotate in opposite directions inside a shaped chamber, creating uniform and gentle fluid transfer without contamination.

The helical twin screw technology incorporated in Raptor pumps ensures a completely sanitary design, with smooth surfaces free from stagnation zones, making these pumps the ideal solution for applications requiring maximum hygienic standards.
