Description

Technical Field

[0001] This utility model belongs to the field of solvent pump technology, and in particular relates to a solvent pump with a sealing structure. Background Technology

[0002] The solvent pump adopts a vertical, energy-saving external stainless steel housing structure, which makes the pump inlet and outlet on the same horizontal line and with the same diameter. It can be installed in the pipeline like a valve. It combines the advantages of high pressure of multi-stage pumps, small footprint of vertical pumps, and convenient installation of pipeline pumps.

[0003] Currently available solvent pumps have the following problems when used:

[0004] 1. Traditional solvent pumps are typically used by directly connecting the inlet and outlet pipes to the surface of the pump body to draw in solvent and then deliver it. If the connection is not properly sealed, there is a risk of solvent leakage, and the sealing effect is poor.

[0005] 2. When traditional solvent pumps are used, the environment is relatively complex, and various solvents in the environment can easily affect the surface of the pump body, which can cause corrosion in severe cases. Therefore, the protection effect on the surface of the pump body is poor. Utility Model Content
