The wastewater treatment industry relies on powerful effluent pumps to move large volumes of wastewater through various stages of treatment. These pumps need to be tough enough to handle abrasive materials and efficient enough to keep operating costs down. We explore two solutions below: heavy-duty effluent pumps designed for various flow rates and self-priming positive displacement pumps for handling viscous and abrasive materials.
Ashland Pump Effluent Pumps
Heavy-duty effluent pumps from Ashland Pump are available in multiple horsepower sizes for various performance requirements, and feature efficient permanent split-capacator motors. The oil-filled pumps have an upper and lower ball bearing design and handle solids up to 3/4 inch. They are heavy-duty cast iron, with cast iron impellers and equipped with a piggyback switch (20-foot standard cord) or in manual configurations. They are offered in 3/10, 4/10, 1/2, 3/4, 1 and 1 1/2 hp models. 855-281-6830; www.ashlandpump.com
Boerger BLUEline
Boerger BLUEline rotary lobe pumps are a self-priming, valveless, positive displacement pump 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.
