This pump is horizontal, single and double pumps, cantilever, shell, centrifugal slurry pump. Adopt modern CAD design method of hydraulic, excellent performance, high efficiency and low wear rate. By paying impeller and packing seal and mechanical seal, combined to ensure no leakage slag pulp. Channel spacious, anti-clogging performance is good, the cavitation performance is superior. Reliability design, ensure the machine average trouble-free MTBF greatly improved.
