Sulzer submersible pumps, mixers and agitators are used to transfer, blend and handle sludge, within biological, secondary and anaerobic digester recirculation processes. For more demanding sludge processes, with high viscosity and high % dry solids (DS) our progressing cavity, positive displacement pump range, provide a near constant flow rate with suction lift capability, for handling wastewater sludge, slurries, and viscous shear thinning non-Newtonian fluids.
The range starts with the entry level, competitively priced PC transfer pump with close coupled drive and gearbox. Our PC transfer perform pump is designed for easy dismantle and reassembly, maintain in place without the need to disconnect, remove suction or discharge pipework. The PC cake pump, with wide throat inlet is built to handle de-watered sludge cake in excess of 30% DS concentration. Progressive cavity dosing pumps are designed for applications where accurate low flow capacities need to be maintained.
