As a result, the HiCone maintains consistently high levels of conveying capacity and energy efficiency, with long service life.
“Due to the conical shape of the rotor and stator, exact readjustments are possible. Unnecessary pressing and squeezing of the stator rubber to ensure internal sealing again are no longer necessary,” says Michael Brinkmann, Director of Global Sales at Vogelsang.
The HiCone is suitable for applications in industry, wastewater and environmental technology.
With the conical rotor-stator geometry, if a gap occurs between the rotor and stator as a result of wear, it can be compensated for during ongoing operation. The rotor is adjusted axially. The size of the conveying chambers, the conveying capacity and the efficiency are the same as at the time of delivery, ensuring constant conveying capacity with high efficiency. Instead of costly, time-consuming parts replacement, the HiCone can be simply and quickly readjusted, increasing its service life many times over.
The smart adjustment system allows the HiCone to be individually adapted to the respective operating parameters, such as pressure and temperature, by optimally positioning the rotor and stator in relation to each other.
“In wastewater treatment plants, for example, the pumping technology needs to withstand high pressures in some cases. If the rotor and stator are ideally adjusted accordingly, the contact pressure between the conveying components, and thus the wear, is reduced to a minimum,” explains Brinkmann. “In terms of energy efficiency, the HiCone’s smart adjustment system has another advantage, ie it requires less energy and the automatic start-up system also enhances this effect.”
Because the rotor and stator are positioned relative to each other to minimize clamping between the two, a smaller motor is required to start the pump than in conventional progressive cavity pumps. This reduces the torque to a minimum when starting up the pump, which in turn improves energy efficiency. The start-up process is fully automatic without the need for additional control. The clamping between the rotor and stator can be regulated from the control room throughout the entire service life during operation, as well as monitored for wear. This makes it possible to plan the replacement of the rotor-stator package.
