The municipal sewer and water industry relies on robust pumping systems to handle everything from clean water to aggressive, solid-laden wastewater. Today's pumps are engineered to tackle the growing challenge of clogging (often caused by modern sanitary products and heavy solids) using innovative vortex, chopper and specialized impeller designs.
Alongside these heavy-duty wastewater handlers, high-precision dosing pumps ensure accurate chemical treatment, while high-pressure plunger systems power mobile hydroexcavation tasks. Built for durability, ease of maintenance and energy efficiency, these diverse pumping technologies keep critical infrastructure running smoothly while minimizing downtime and operational costs.
Boerger BLUEline
Boerger BLUEline rotary lobe pumps are self-priming, valveless positive displacement pumps used for conveying viscous and abrasive materials. They are resistant to wear and provide pulsation-free operation. Operation is fully reversible with dry-run capability and flow rates up to 7,000 gpm. They are constructed with maintenance-in-place design, allowing for all wetted parts to be easily replaced through the front cover without removing pipe or drive systems. The pump conveys biosolids (primary, waste activated sludge, return activated sludge, digested, thickened, etc.), grease, sewage, scum, lime slurry, alum sludge, permeate and polymers. 612-435-7300; www.boerger.com
Cat Pumps 3560 and 3560T14
Cat Pumps 3560 and 3560T14 plunger pumps deliver reliable power for hydroexcavating, jetting and other demanding mobile cleaning work. The 3560 combines a solid 316 stainless steel discharge manifold, industry-proven drive end and a service-friendly design to maximize life and simplify maintenance. Performance is up to 20 gpm at 4,000 psi or 25 gpm at 3,000 psi. Multiple drive options are available to fit your build with the 3560 accepting belt-drive or direct-drive configurations with a hydraulic motor, bell housing and flexible coupler. For spline-shaft motors, the 3560T14 uses a direct-mount SAE-C flange and 14-tooth hollow shaft that eliminates the bell housing and reduces the width by more than 8 inches, freeing cabinet space and streamlining pump installation. 763-780-5440; www.catpumps.com
Dynablast Pratissoli KFR25
The Pratissoli KFR25 water pump, distributed by Dynablast, offers 19.4 gpm at 3,200 psi at 1,000 rpm. It is available on a coupler-driven hydrovac skid or T14 female spline shaft input and SAE C 2/4 bolt flange for direct mounting to the hydraulic motor. It has run-dry seals, Kevlar graphite rope, a 420 stainless steel manifold for protection from cavitation, stainless steel valve cages for protection from cavitation, a self-lubricating design with no weekly oil lubrication required, a symmetrical crankcase that makes it easy to reverse-shaft the pump, internal fins on its aluminum crank case to provide cooling to lower the oil temperature, a tapered roller bearing for improved lateral loading and two bore ceramic plungers that are thicker ceramic on the water end to prevent thermal shock. 905-867-4642; www.dynablast.ca
Pentair XRW Series
Pentair XRW Series pumps are designed to solve clogging. Rather than relying on grinding or chopping mechanisms, they use Xcentric technology, an impeller design that keeps solids moving smoothly through the pump. The Xcentric features an oblique cone geometry and eliminates traditional vane leading edges, preventing blockage from wipes, rags and other solids. Field testing and operational data show that it maintains consistent performance and high hydraulic efficiency without clogging. Available in vertical or horizontal configurations, it handles flows up to 13,000 gpm and heads up to 200 feet, making it a dependable choice for municipal and industrial wastewater systems. Its design reduces vibration and capacity drift, leading to significant improvements in energy efficiency and a lower total cost of ownership. 913-371-5000; www.pentair.com
Pulsafeeder NextStep
NextStep dosing pumps from Pulsafeeder are designed for high-resolution metering control and reliability and cover a wide range of applications including polymer feed applications. When “once through” or nearly constant chemical discharge and even distribution of flow is beneficial, NextStep stepper motor pump provides high dosing accuracy, digitally controlled, high turndown ratio of 3,333-1, reducing pulsation and increasing the reliability of metering off-gassing and high-viscosity chemicals. Modbus or RS-485 communication keeps the process running smoothly even from a remote location. All needed valves, tubing and cables are in the box, even a foot valve with integrated low tank level alarm. 800-333-6677; www.pulsafeeder.com
Sanicubic 2 VX
SFA Saniflo’s Sanicubic 2 VX is a 1.5 hp heavy-duty duplex Vortex system used to pump away wastewater from multiple fixtures in a single structure. This system can discharge the waste up to 36 feet vertically through a 2-inch-diameter pipe or up to 20 feet when discharging through a 4-inch pipe. It incorporates a two-pump Vortex system that is ideal for uncontrolled, heavy-traffic environments in both residential and commercial applications. The product is specially designed to handle larger sanitary products that may have been mistakenly or carelessly flushed down the toilet, including condoms, sanitary napkins, Q-tips, dental floss, etc., as well as large-diameter solids. 800-571-8191; www.sfasaniflo.com
Vaughan Chopper Pump
Self-priming Chopper Pumps from Vaughan are designed to be easily accessed outside of the wet well while pumping waste solids at heavy consistencies without plugging or dewatering of the solids. They eliminate the loss in production and mess along with making it easy to service the pump to get it back in operation. 888-249-2467; www.chopperpumps.com
