Archimedean Screw Pumps for Wastewater Systems
Modern wastewater systems rely on equipment that can handle variable flow, solids, and harsh operating conditions. Dutco Tennant LLC supplies Archimedean screw pumps engineered to support wastewater movement with smooth, controlled lifting while minimizing operational strain. These wastewater screw pumps are widely used in facilities where continuous flow, reliability, and energy efficiency are critical, especially as part of pre-treatment equipment.
Many industries and municipalities prefer screw pumps because they operate at low speed, manage solids with ease, and ensure stable pumping performance. Whether used in sludge handling screw pump setups, open channel pumping, or effluent transfer, the technology supports efficient and consistent hydraulic movement without requiring complex controls. They are also compatible with complementary systems such as conveyors designed for wastewater and sludge transport.
Water treatment screw pumps operate using a rotating screw that gently transports water or sludge upward. The movement avoids turbulence, shear force, or clogging, making the solution suitable for raw sewage, thick sludge, and wastewater with suspended solids. Heavy-duty screw pumps also perform reliably under fluctuating flow loads, making them a preferred option in wastewater treatment equipment and advanced sludge treatment equipment.
Another strength of screw pump systems is adaptability. They can be supplied in various lengths, diameters, and capacities, allowing them to integrate easily with new or existing treatment lines. From sludge dewatering system units to industrial wastewater channels and effluent lifting stations, this design serves a wide range of applications—particularly when paired with sludge dewatering equipment.
