Progressive cavity pump
Our progressive cavity pumps are high-quality products, which are manufactured for a wide range of applications. In order to be able to offer you the right pump, the material composition of the progressive cavity pump is individually designed according to the existing medium.To get more news about screw pump stator, you can visit hw-screwpump.com official website.
The NF progressing cavity pump is a compact and cost-effective pump which is easy to install and does not require a separate base frame. For flow rates of up to 30 m³/h, this series is a good alternative to the N series. In this design, the gear motor is screwed directly to the progressive cavity via a flange.
For all applications where elastomer stators can be used, an adjustable stator is available, which significantly increases economic efficiency.The stator can be continuously adjusted over a wide range when the pump performance decreases; this extends the service life of the stator by a factor of 4 to 6. The special design of the adjustable stator ensures a radially uniform contact pressure and full tightness.
For pumping fluid with high viscosity and high content of mechanical impurities and the installations of the screw pumps that allow us to control and regulate the technological parameters of production gas are used. The research of efficiency of screw pump revealed that the failure of the cage (stator) and wear of the stator – rotor, accompanied by a decrease in performanceThe wear of the pair of stator and rotor, extended condition normal operation of the screw pump are studied, taking into account the orientation of the working screw, the effect of inertial and hydraulic forces, physical and mechanical properties of the contact layers. This considerably improves the durability and manufacturability of the screw pumps.
