Wastewater Pumps
Heavy-duty pumping solutions engineered for reliable wastewater transfer, lifting, and circulation in demanding applications
Overview
What is Wastewater Pumps?
Wastewater pumps form the circulatory system of treatment plants and collection networks, reliably moving raw sewage, sludge, and treated effluent through various process stages. These specialized pumps are designed to handle solids, fibrous materials, abrasive particles, and corrosive chemicals that would quickly damage conventional pumps.
Different pump technologies serve specific applications throughout wastewater systems. Submersible sewage pumps lift raw wastewater from collection sumps. Non-clog centrifugal pumps transfer screened wastewater between treatment stages. Progressive cavity pumps dose sludge and chemicals. Vertical turbine pumps provide high-head applications. Each design incorporates features to ensure continuous, trouble-free operation.
Spans Envirotech supplies comprehensive wastewater pumping solutions from leading manufacturers, backed by expert selection, installation, and service support. Our pump systems feature wear-resistant materials, efficient hydraulic designs, and smart monitoring capabilities to maximize reliability while minimizing energy consumption and maintenance costs.
Process
Pump Technologies
Submersible Sewage Pumps
Sealed motor-pump units installed in wet wells handle raw sewage containing solids up to 3 inches. Vortex or channel impellers prevent clogging. Automatic level controls start/stop pumps based on demand.
Centrifugal Process Pumps
Above-ground pumps with open or semi-open impellers transfer screened wastewater. Non-clog designs pass solids up to 3 inches. End-suction, split-case, and vertical configurations suit different installations.
Progressive Cavity Pumps
Positive displacement pumps handle viscous sludge, polymer solutions, and abrasive slurries. Rotor-stator geometry creates cavities that progress from suction to discharge, providing gentle, pulsation-free flow.
Diaphragm & Peristaltic Pumps
Seal-less designs ideal for chemical dosing and abrasive slurries. Diaphragm pumps provide accurate metering. Peristaltic pumps eliminate fluid contact with pump components.
Monitoring & Control
VFDs adjust pump speed to match flow requirements. Vibration sensors, temperature monitors, and current analyzers detect problems early, enabling predictive maintenance.
