Positive displacement pump
With decades of experience, Herold put his knowledge into this extraordinary positive displacement pump; which includes cutting-edge technology - sanitary certificate, sliding cartridge seals, robust materials, treated surfaces and unmatched energy efficiency. Due to its special design, our rotary lobe pump has the lowest pulsation levels in the world, which generates energy savings and minimizes wear on all parts of the pump and pumping line.
A Herold pump is designed to last for decades. The contact-free lobes ensure not only a long life, they also generate savings and reduction in production losses. If you plan to renew your production process, a Wendelkolben Herold pump can be the ideal choice in both high viscosity and low viscosity interchangeably. For the sugar industry, special stress-free mechanical seals were developed, independent of the direction of rotation and suspended by springs out of the middle, in our standard version the O-rings are made of Viton and the faces of carbide tungsten.
Advantages
The mechanical seals are cooled and lubricated by a Quench system at zero pressure, the seals are selected and adapted for each individual pumping process:
Atmospheric separation Can rotate in both directions Quench cooling and lubrication system FDA certified O-rings for every application
Technology
The world's lowest pulsation is just one of the outstanding properties of Herold W's innovative pump technology. Suction sealing lines and casing discharge area match the sinusoidal and cosinusoidal configuration of the rotors. This prevents turbulence. Due to the aerodynamic shape of the suction and discharge, the risk of cavitation is reduced.
Lowest pulsation level worldwide Lower energy consumption Highest quality without shredding Designed to last
Compared to ordinary rotor pumps, the Herold WK's rotors are rotated 90 °. Its optimized sinusoidal design implements a superior opening area at the same angle of rotation, responsive pumping, and lower flow rate.
