About UsHebei Naimo Pump Co., Ltd. was established in 2016, with a registered capital of 10 million, is located in the township of the Chinese pump, Shijiazhuang.Naimo are specialists in the design, manufacture and service of slurry
NV(R) sump pump
Type NV (R) pumps are single-stage，single-suction，cantilevered, vertical, centrifugal slurry pump. They are designed for delivering abrasive，rarge particle and high density slurries. These pumps have no need of any shaft sea | and sealing water，they can also be operated normally for insufficient suct ion duties，especially suitable for used as all kinds of pit pump in mines and coal preparation system.
