MVS series axial-flow pumps AVS series mixed-flow pumps (Vertical axial flow and Mixed flow submersible sewage pump) are modern productions successfully designed by the means of adopting foreign modern technology. The new pumps’ capacity are 20% larger than the old ones. The efficiency is 3~5% higher than the old ones. MVS & AVS series pump with adjustable impellers has the advantages of large capacity, broad head, high efficiency, wide application and so on. The material of the series of AVS/MVS Axial flow and Mixed flow submersible pump can be casting ductile iron copper or stainless steel.
