What are Sanitary Pumps?
The sanitary pump is a kind of classification of pumps in use, which involves the transportation of all products with human contacts, such as pharmaceutical, dairy, beverage, food, cosmetic, food additive, fine chemical and so on.
There are four basic types of sanitary pumps: centrifugal, volumetric, jet and airlift. Centrifugal pumps use centrifugal force to generate speed and use rotating impeller to increase speed and push fluid through the outlet valve. Positive displacement pumps use rollers, gears, or impellers to move fluid into a fixed cavity so that when liquid exists, the vacuum that is created draws in more fluid. Jet pumps force fluid through a nozzle, converting the fluid’s energy into velocity energy. Airlift pumps mix air or gas with the liquid media so that the air-liquid mixture, with a lower specific weight than the liquid, rises in the pipe and is discharged above the level of the liquid.
From the material of the pump, the sanitary pump must be 316L stainless steel, and there is no sanitary dead angle in the pump chamber. The sealing material of the sanitary pump is food-grade material, such as nitrile rubber, fluorine rubber, ethylene-propylene rubber, Teflon and so on. From the type of pump, centrifugal pump, rotor pump, self-priming pump, shear pump, screw pump, etc., as long as the above requirements are met can be referred to as sanitary pump. In terms of industry standards, the sanitary pump must be certified as American 3A, European EHEDG, and the materials meet FDA standards.
The sanitary pump is also known as centrifugal beverage pump, milk pump, stainless steel beverage pump, which is suitable for conveying milk and other similar colloid liquid food use. Nowadays, sanitary pumps are used in a variety of commercial and industrial applications. Examples include agriculture and horticulture, brewery and distillery, dairy, food processing, food service, medical, municipal, OEM supply, and pharmaceutical and biotechnology applications.
