1 Classification according to the working principle and structure
1) Vane pump: When the pump shaft rotates, various impeller blades are driven to impart centrifugal force or axial force to the liquid, and the liquid is transported to the pipeline or container, such as a centrifugal pump, vortex pump, mixed flow pump, and axial flow pump.
2) Positive displacement pump: a pump that uses the continuous change of the volume in the pump cylinder to transport liquid, such as a reciprocating pump, piston pump, gear pump, or screw pump.
3) Other forms of pumps: there are electromagnetic pumps that use electromagnetism to transport liquid electrical conductors; pumps that use fluid energy to transport liquids, such as jet pumps, air lifters, etc.
2 Types Of Chemical Pumps Classified By Chemical Use
1) Process pump: including feed pump, return pump, circulation pump, flushing pump, sewage pump, supplementary pump, output pump, etc.
2) Public works pumps: including boiler pumps, cooling tower pumps, fire-fighting pumps, deep well pumps for water sources, etc.
3) Auxiliary pump: including lubricating oil pump, sealing oil pump, hydraulic transmission pump, etc.
4) Pipeline transfer pump: pump for an oil pipeline, pump for loading and unloading truck, etc.
3 Types Of Chemical Pumps Classified By Conveying Medium
1) Water pump: including clean water pump, boiler feed water pump, condensate pump, and hot water pump.
2) Corrosion-resistant pumps: including stainless steel pumps, high-silicon cast iron pumps, ceramic acid-resistant pumps, impermeable graphite pumps, hard rubber-lined pumps, hard PVC pumps, canned pumps, diaphragm pumps, titanium pumps, etc.
3) Impurity pump: including slurry pump, sand pump, sewage pump, pulverized coal pump, ash pump, etc.
4) Oil pump: cold oil pump, hot oil pump, oil slurry pump, liquid hydrocarbon pump, etc.
