Pumping of undigested dewatered sludge with Kronoa Vertical Pumps

February 24, 2025

In various industries and wastewater treatment plants, managing undigested dewatered sludge presents challenges due to its high solid content and viscosity. These residues, which have not undergone anaerobic digestion, require specific pumping solutions for efficient handling.

Efficient pumping with Kronoa Vertical Progressive Cavity Pumps

Kronoa’s vertical progressive cavity pumps are designed to handle this type of sludge with reliability and efficiency. In these processes, sludges dewatered to 20-25% dry matter are typically fluidised and mixed until they reach 10-12%, allowing for obstruction-free pumping.

Thanks to their robust design, Kronoa vertical pumps from the V series can transport highly viscous fluids with a high solid content. Furthermore, they can be manufactured in various configurations to meet the specific needs of each installation, with capacities of up to 100 m³/h.

Applications in sludge reception plants

Plants specialising in the reception and handling of such sludges require tailored pumping systems. Kronoa vertical pumps, when combined with an appropriate agitation system, allow for a homogeneous mixing of the sludge up to 12-14% dry matter, facilitating its transport and processing.

Protech Continental’s experience in installations

Protech Continental, a company with extensive experience in these types of installations, has integrated Kronoa vertical pumps into its substrate reception systems, known as BIO-Gut.

Progressive Cavity Pump performance starts long before installation: the engineering parameters that really matter

August 20, 2026

The continuous, reliable displacement of complex fluids is a cornerstone of modern industrial processing. When managing media characterised by extreme thixotropy, high solids content, or abrasive particles, selecting the correct pumping architecture is critical to avoiding structural component fatigue and accelerated internal wear.
