ALLDUR® Stators
Maximum Wear Resistance for Progressing Cavity Pumps
Up to 500% longer service life. Minimize downtime. Lower your TCO.
Stator lifetime starts with the right compound. The formulation determines how long your pump maintains its flow rate and how much you spend on maintenance and spare parts over time. At Allweiler, we engineered ALLDUR® stators specifically for our progressing cavity pumps, focusing on maximum cost effectiveness. With outstanding wear resistance and proven long service life, ALLDUR® turns durability into lasting savings.

Solution
Why Choose ALLDUR®?
Experience the power of ALLDUR® stators—engineered for exceptional durability and value in progressing cavity pumps. From the moment you double the lifetime of your stator, your savings begin, since ALLDUR® stators are only about 90% more expensive than standard Perbunan (NBR) stators. Doubling your stator's lifespan is easily achieved, especially when pumping abrasive media. In fact, proven references show ALLDUR® stators can deliver up to 500% longer lifetimes, and in some cases, even more. Choose ALLDUR® for your next project and discover a solution that not only extends performance but also transforms your operational efficiency.
Is ALLDUR® Right for Your Application?
ALLDUR® stators are designed to tackle the toughest pumping challenges. If your operations involve media with high solids content or highly abrasive substances, ALLDUR® offers a solution that delivers lasting reliability. Customers experiencing frequent mechanical wear and short stator lifespans will find ALLDUR® particularly beneficial, as it significantly reduces the need for constant maintenance and readjustment.

Unlocking Efficiency
ALLDUR® Stators Based on Honeycombs
Our ALLDUR® stators use nature-inspired technology to optimize the performance of Allweiler progressing cavity pumps. Thanks to an innovative honeycomb structure on the stator surface, they minimize hydrodynamic resistance and enable higher efficiencies. The special feature of ALLDUR® stators is that they absorb the liquid phase of the pumped fluid on their surface. This minimizes hydrodynamic resistance, resulting not only in higher efficiency but also in energy savings.
Another impressive feature of ALLDUR® stators is their ability to reduce the internal friction of progressive cavity pumps by up to 500 % compared to conventional solutions. This has a direct impact on starting and operating torque, allowing operators to pump more fluid with significantly less effort and energy consumption.
Experience
Proven Service Life Under Real Operating Conditions
The Cologne-Stammheim wastewater treatment plant tested ALLDUR® stators under highly abrasive conditions. Results: Conventional stators showed severe wear after 4 months, requiring replacement after 7 months. In contrast, ALLDUR® stators maintained performance for over 2 years with only minimal capacity loss. This durability compensated for the higher initial cost and reduced energy consumption associated with increased pump speeds.
