Water has always shaped the infrastructure and sustainability of civilizations—and so has the need to control and treat it. Today, as the Middle East faces growing demands for efficient wastewater management, energy conservation, and sustainable infrastructure, the importance of selecting the right pumping technology becomes paramount.
At Dutco Tennant LLC, we bring the power of timeless engineering to the modern world through our partnership with Sismat Uluslararası, a global leader in water and wastewater treatment equipment. Our featured solution—Archimedean Screw Pumps—is a perfect example of how centuries-old ingenuity can meet 21st-century environmental challenges.
These screw pumps combine simplicity, strength, and efficiency to move large volumes of wastewater, sludge, or stormwater with minimal energy consumption and maintenance. Designed to operate in the toughest environments, they are ideal for municipal sewage plants, sludge handling, dewatering systems, and industrial effluent lifting across the UAE and GCC.
Product Overview: Sismat Archimedean Screw Pumps
Sismat's Archimedean Screw Pumps are a heavy-duty, open-channel pumping solution ideal for high-capacity and low-head applications. Based on the Archimedean principle, these pumps consist of a large helical screw rotating inside a stationary trough. The rotation lifts water or sludge gently, preventing turbulence, clogging, and mechanical wear.
With their gravity-fed operation and non-clogging design, these wastewater screw pumps are particularly effective in moving sludge, raw sewage, stormwater, or other effluents containing solids or fibrous materials. Their open construction makes them ideal for installations where visibility, inspection, and easy cleaning are required.
Backed by decades of field-proven results, these pumps are now widely used in some of the most demanding municipal and industrial projects across the globe—and with Dutco Tennant, they’re available locally with full service support throughout the UAE and GCC.
Key Features & Highlights
- Heavy-Duty Construction: Built using corrosion-resistant stainless steel or coated carbon steel, these pumps are engineered to perform in harsh and chemically aggressive environments.
- Energy-Efficient Performance: Operates at low rotational speeds with minimal power consumption, making it one of the most sustainable pumping options for wastewater applications.
- Open Channel & Self-Cleaning Design: The screw pump’s open construction eliminates clogging and simplifies maintenance by allowing easy access to moving components.
- No Priming Required: Operates without the need for suction or priming, even in conditions with fluctuating water levels.
- Highly Customizable: Can be manufactured to match a wide range of diameters, lengths, slopes, and capacities based on project requirements.
- Low Maintenance Requirements: With fewer moving parts and low operating stress, these pumps require minimal servicing and offer long operational life.
- Silent Operation: Operates quietly, making them suitable for urban and noise-sensitive zones such as municipal plants near residential areas.
- Non-Clogging Action: Handles raw sewage, fibrous material, sludge, and screenings without damage or performance issues.
Application Areas
Sismat Archimedean Screw Pumps are trusted across various sectors where fluid lifting, sludge transfer, and dewatering are critical. Their adaptability and durability make them perfect for the following applications:
Municipal Wastewater Treatment
Ideal for preliminary pumping stations and sludge transfer systems, ensuring reliable lifting of influent and primary sludge with minimal risk of clogging.
Industrial Effluent Handling
In manufacturing, chemical, and food processing plants, these pumps handle contaminated water with varying solids content and viscosity levels.
Sludge Dewatering Systems
Perfect for integration into thickening or sludge dewatering systems, transporting viscous sludge to centrifuges, screw presses, or digesters.
Open Channel Pumping Stations
Used in stormwater and surface water pumping stations to lift large volumes of water with fluctuating flow rates.
Irrigation & Agricultural Drainage
Efficiently lifts drainage water or treated effluent for reuse in landscaping, agriculture, or dust control in arid environments.
Effluent Lifting in Sewage Plants
Critical in transferring secondary or tertiary treated effluent to disposal or reuse stages, especially in MBR and extended aeration systems.
