According to the type of matching power machine of the pump, it is divided into electric motor matching self-priming pump and diesel engine matching self-priming pump. According to the structure and working characteristics of achieving self-priming function, it can be divided into internal sliding type, external sliding type, water ring wheel type, and other types. The transmission methods include direct drive (including inner shaft) and belt drive. Imported diameters range from 25 to 200 millimeters, with a total of 10 calibers and 54 specifications. ·Centrifugal pump models: There are many types of centrifugal pumps, and only a part of them will be introduced here. If you want to know the specific meaning of the models, you need to consult the centrifugal pump manufacturer. First, let's take a look at the meanings represented by the letters of all pump product models- B: Single stage single suction cantilever centrifugal pump- D: Segmented multi-stage pump- DG: Segmented multi-stage boiler feed pump- DL: Vertical multi-stage pump- DS: Segmented multi-stage pump with double suction impeller for the first stage- F: Corrosion resistant pump- JC: Long axis deep well pump- KD: Open type multi-stage pump- KDS: A multi-stage pump with double suction impellers in the first stage and a central opening design- QJ: Submersible pump for wells- QX.: Single phase dry submersible pump- QS: Water filled submersible pump- QY: Oil filled submersible pump- R: Hot water pump- S: Single stage double suction centrifugal pump- WB: High head horizontal axis sewage pump- Y: Hydraulic pump- YG: Pipeline hydraulic pump- ZB: Self priming centrifugal pump. At present, there are a total of 32 models of centrifugal pumps, including ISG pipeline centrifugal pump, ISW horizontal pipeline centrifugal pump, QDLF stainless steel multi-stage centrifugal pump, GC boiler feedwater centrifugal pump, DL vertical multi-stage centrifugal pump, GDL multi-stage pipeline centrifugal pump, PBG shielded pipeline centrifugal pump, YG vertical pipeline oil pump, ISWR horizontal hot water pump, ISWH horizontal chemical pump, ISWB horizontal pipeline oil pump, ISG vertical pipeline centrifugal pump, IRG vertical hot water circulation pump, IHG vertical pipeline chemical pump, ISGB detachable pipeline centrifugal pump, ISGD low-speed centrifugal pump, ISWD low-speed centrifugal pump, IS single-stage single suction clean water centrifugal pump, IH single-stage single suction chemical centrifugal pump, FS horizontal fiberglass centrifugal pump, S-type fiberglass centrifugal pump, GBW concentrated sulfuric acid centrifugal pump, FSB type fluorine pump.
