In modern wastewater treatment systems, selecting the right sludge pump is essential to ensure reliable operation, reduce maintenance costs, and achieve regulatory compliance. The Roto DM Series Progressive Cavity Pump is specifically engineered to handle high-viscosity sludge, abrasive fluids, and liquids with solid content—making it an ideal solution for both municipal and industrial wastewater treatment plants.

Why Choose Roto DM for Sludge Pumping?

The Roto DM pump operates on a single-screw progressive cavity principle, which generates a consistent, pulsation-free flow. This is critical when transferring biological sludge, thickened sludge, or slurry, as it helps protect sensitive treatment processes and prevents clogging.

✅ Handles viscous and abrasive media – Capable of pumping sludge with solid particles, fibrous content, and high solids concentration without compromising performance.
✅ Low shear pumping action – Maintains the integrity of sludge and biological materials, which is important in aerobic and anaerobic treatment processes.
✅ Durable and low maintenance – Built with wear-resistant components and designed for easy servicing, reducing downtime and operational costs.
✅ Flexible installation – Available in various configurations (baseplate-mounted, vertical, or close-coupled) to adapt to different plant layouts and space restrictions.

Common Applications:

• Primary and secondary sludge transfer

• Thickened and digested sludge handling

• Dewatering system feed pump

• Slurry transport in mining and cement

• Viscous food waste and industrial effluents

Trusted Solution for Long-Term Operation

With proven performance in thousands of installations worldwide, the Roto DM sludge pump is a trusted choice for wastewater treatment professionals who require efficiency, longevity, and easy integration into existing systems.
