Laboratory circulation pump

The laboratory circulation pump uses an electric motor to drive the impeller, creating a negative pressure that enables continuous liquid flow within a closed pipeline. It is used for temperature control in devices such as constant temperature baths and reaction vessels, ensuring uniform circulation of the medium.
Selection
Match pump parameters based on required flow rate and head, select corrosion-resistant materials considering the corrosiveness of the medium, choose sealing methods according to the operating temperature, determine pump body structural dimensions based on installation space, and verify interface specifications to ensure pipeline compatibility.
