MAINTENANCE REQUEST FORMS: PUMP REPAIR REQUEST FORM | PICKUP REQUEST FORM
Wangen’s range of progressive cavity (helical rotor) pumps starts with the Wangen Xpress Series. These pumps are a go-to progressing cavity-type and are designed to pump fluids with ease of maintenance and greater reliability. These pumps have the smarts of simple but effective German engineering along with a high-quality Made in German product.
All-Pumps stock these pumps complete with baseplates and geared motors with flows from 5m3/hour to 102m3/hour, ready to be shipped to your facility the same day. These pumps can handle treatment plant waste through to bentonite slurries. Be sure to watch the video below showing minimal maintenance.




Wangen Pumpen Progressive cavity pumps employ a positive displacement working principle. The design of this pump consists of a motor at the drive end connected to a gearbox as pc pumps operate at low rpm compared to centrifugal pumps. The output shaft from the gearbox connects to a rotor via a universal pin joint which rotates a metallic rotor within a rubber stator. Stators contain cavities, and the rotor pushes fluids through the cavities in a slow rotating fashion. As the rotor begins to move eccentrically, the cavities form, draw in product and are ‘progressed’ along with the assembly and the product is expelled through the discharge port.
