Design Instruction
NH Series chemical chemical process pump is the latest pump product replaced by the IH Series. The performance parameter and installment drawing as the same as the IH Series.T his pump executed Standard GB/T5662 < The Marks. Performance and specification of Axial Direction end-suction centrifugal pump (16 bar )> .with highly interchangeable for the general spare parts pump. Five specification brackets of the pump can cover full series specification pumps.
It can be chosen gland packing or mechanical seal according to the client's request. Mechanical seals can choose a single (end) face， double(end) face, balanced face,e or imbalance face. The impeller can be designed with open-type or semi-open type. It can transfer certain fiber or particle liquids. It is
generally a standard chemical centrifugal pump in fine chemical fields.
