Wastewater screw pump for municipal treatment
Optimize your wastewater management with precision and reliability, handling liquids and slurries efficiently while minimizing maintenance and maintaining performance over time. Perfect for operations requiring consistent volumetric flow rates even under varying submersion conditions.

Lifts and Conveys Contaminated Water Efficiently
The Wastewater Screw Pumps PA from WAMGROUP are engineered to excel in water management across municipal and industrial settings. These Archimedean screw pumps use a volumetric lifting mechanism, allowing them to adjust flow rates automatically with varying submersion of the screw, minimizing energy loss and operating costs. Suitable for applications in wastewater treatment, irrigation, and food packaging, these pumps handle liquids with suspended solids effectively. With diameters up to 4 metres and flow rates reaching 4,500 litres per second, the PA series is designed for demanding environments, ensuring constant efficiency and minimal maintenance. Drive power options up to 500 kW enhance their operational capacity, while robust construction supports durability and extended service life in even the most challenging conditions. Their integration capability and potential for customization enable seamless fit into existing processing lines, supporting continuous, efficient operation.
