Moving wastewater, sludge and other solids-heavy materials requires equipment built for demanding conditions and minimal downtime. Advances in positive displacement, submersible and grinding technologies are helping operators in municipal and environmental sectors manage abrasive media, reduce clogging and simplify maintenance. From dewatering applications to sewer cleaning and sludge transfer, modern pumping systems are designed to withstand harsh environments and support more efficient handling of challenging fluids and solids.
Boerger rotary lobe pumps
Boerger rotary lobe pumps are designed to convey septage, sludge and other solids-laden fluids commonly encountered in wastewater and septage management operations. As positive displacement pumps, they deliver a consistent flow while handling viscous and abrasive media with minimal pulsation. The pumps are self-priming and capable of reversible operation, making them suitable for applications such as septage receiving stations, sludge transfer and tank or pit clean-out. Their valveless design allows fibrous materials, wipes and other debris commonly found in septage to pass through the pump with reduced risk of clogging. A key feature of the pump is its Maintenance in Place design, which allows operators to replace wear components quickly without removing the pump from the piping system. This simplifies routine service and reduces downtime. They are used in municipal and industrial wastewater facilities for reliable septage and sludge handling. 612-435-7300; www.boerger.com
Idee e Prodotti TARUA
The TARUA from Idee e Prodotti is a positive displacement pump that simultaneously vacuums water and solids. Unlike conventional systems, it features a full-passage design, meaning everything entering the suction hose passes through the pump body without restriction. No protective filters or grinders are required. Special accessories allow in-line chemical dosing without separate dosing pumps, simplifying treatment. The system operates like a vacuum truck but continuously, with flow rates of 1,060 to 1,766 cubic feet per hour, and can be coupled with the DRY BOX dynamic gravity dewatering system, installed in a roll-off container. Using filtro-dynamic separation (active filtration) it enables volume reduction and transport in a single step. Applications include industrial and municipal wastewater treatment plants, sewer and pipeline cleaning, drilling sludge management, mining operations and cleaning industrial tanks without emptying them. www.pumps-dewatering.com
Pioneer Pump Minetuff Series
Franklin Electric’s Minetuff Series of electric submersible dewatering pumps from Pioneer Pump are specially designed for deep wells or space-limited sites. The pumps come in 8 to 140 hp and are designed to work in harsh environments from wastewater to mining to construction. Features include heavy-duty motors with integrated thermistors to protect against thermal overload, durable mechanical seals, duplex stainless steel impellers for toughness and corrosion resistance, polyurethane-coated wear parts and light aluminum castings with thick walls for durability. 844-250-4982, www.pioneerpump.com
Zoeller Pump 840 Reversing Grinder Pump
The 840 Reversing Grinder Pump from Zoeller Pump changes cutter rotation with every pump cycle, alternating between clockwise and counterclockwise to minimize the risk of stringy materials wrapping around the cutter. This feature extends the life of the cutter assembly and keeps the system running smoothly. Designed for versatility, it features a 1 1/4-inch NPT discharge that allows for both vertical and horizontal installations. Its rugged, finned cast iron construction and corrosion-resistant, powder-coated epoxy finish deliver lasting durability in demanding environments. The oil-filled, hermetically sealed motor is built with Class F insulation, thermal protection, leak detection and dual shaft seals for reliable operation and enhanced motor life. Plus, compatibility with competitor rail systems makes it a smart, adaptable solution for new or retrofit installations. 800-928-7867; www.zoellerpumps.com
