Sludge, an inevitable byproduct of industrial and municipal wastewater treatment, poses severe challenges to traditional pumping equipment due to its high viscosity, high solid content, strong abrasiveness, and complex rheological properties. Among various pump types, the sludge progressive cavity pump (PCP), with its unique positive displacement principle and outstanding performance, has become the preferred solution in the field of sludge transportation.
Today, combining laboratory data and on-site operating conditions, we deeply analyze the four core application scenarios of single-screw pumps.
Single-screw pumps are not only favored in the environmental protection industry but also irreplaceable in the energy and chemical industries.
Applicable media: Lubricating oil, fuel oil, various refined oils, and macromolecular polymers.
Technical advantages: It is extremely proficient in transporting various viscous liquids. Thanks to its cavity displacement principle, when handling these oil-based media that are prone to adhesion and have slow flow rates, it can maintain high volumetric efficiency without the common problems of cavitation or sudden efficiency drop in centrifugal pumps.
Single-screw pumps are particularly suitable for transporting viscous liquids. Depending on the pump type, they can handle media with a viscosity range of up to 37,000 to 200,000 centipoise (cP) — covering most industrial fluids such as lubricating oil, heavy oil, asphalt, polyacrylamide (PAM) solution, latex, and resin. Their pulse-free and constant flow characteristics ensure stable pressure during transportation and avoid system impact.
This is the "strength" of screw pumps. It can safely transport:
In certain operating conditions, the physical structure of the medium itself must not be damaged (e.g., flocculated sludge or specific polymer solutions).
Stable pressure: Single-screw pumps can provide extremely stable output pressure, free of pulsation and impact.
Low shear force: If you require the original structure of the medium to remain intact, the single-screw pump is currently the optimal solution. It transports the medium gently like a "pusher," unlike centrifugal pumps that hit and cut the medium at high speed through impellers, thereby protecting the chemical and physical properties of the material.
Whether it is municipal and industrial sludge treatment, transportation of high-viscosity oils and macromolecular polymers, transfer of complex media containing particles or fibers, or low-shear process scenarios sensitive to medium structure — these four core application scenarios of sludge progressive cavity pumps fully reflect the technical advantages of Teffiko screw pumps.
