A sludge pump must be very resistant to abrasion. Wear at the wetted parts can occur from the solid content in the fluid. Sludge and slurry are often pumped below the pump unit itself. Good priming capabilities are therefore very important for a sludge pump.
Example applications of pumping slurry-like fluids are anaerobic-treated sludge and raw sludge. Each slurry type varies in its solid content and viscosity has their own physical appearance. Anaerobic sludge has a lower temperature then raw sludge. ...Continue Reading →
