Construction of a Progressing Cavity Pump From NETZSCH Versatile, innovative, high-performance: This is precisely what the construction of the universally applicable progressing cavity pump from NETZSCH stands for. We explain how progressing cavity pumps are constructed and how they operate. They belong to the group of rotating positive displacement pumps. The main components are a rotating rotor and a stationary stator.To get more news about progressive cavity pump rotor, you can visit brysonpump.com official website. In addition to the rotor and stator, the classic design of the progressing cavity pump also includes the power train, a shaft seal, the suction and discharge casing and the drive. This is how progressing cavity pumps are constructed: The helically wound rotor moves in a rotating, oscillating manner in the stationary stator. It is around a threaded screw with a large pitch, a significant thread depth, and small core diameter. It is hinged or elastically mounted on one side. NETZSCH offers numerous different geometries. The same design of progressing cavity pumps results in a modular construction system. This allows you to adjust the flow rate and pressure of installed pumps even later by replacing the rotor-stator unit. Rotors for progressing cavity pumps from NETZSCH are available in wear- and corrosion-resistant designs up to the wear-free ceramic rotor NEMO CERATEC®. The most significant advantage of ceramic rotors over metallic ones is their physical hardness; only diamond is more complex. All media with which the NEMO CERATEC® comes into contact are softer than this. This excludes the possibility of damage to the contact surfaces. Ceramic rotors thus offer you extremely high wear resistance.
