A sanitary pump is a pump specially designed to meet high hygiene standards. It is widely used in pharmaceutical, food, cosmetics, biotechnology and other industrial fields that require safe fluid transmission. The following is a detailed explanation of sanitary pumps
1. Definition and classification
Definition: Sanitary pumps are classified according to the occasion of use of the pump, specifically involving the delivery of all products that come into contact with the human body, such as pharmaceuticals, dairy products, beverages, food, cosmetics, food additives and fine chemicals.
Classification:
According to the working principle, sanitary pumps can be divided into centrifugal, positive displacement, jet and air transport types.
According to common types, including centrifugal pumps, rotor pumps, self-priming pumps, shear pumps, screw pumps, etc., as long as they meet the hygiene standards, they can be called sanitary pumps. Among them, the impeller of the centrifugal pump must be an open impeller to be a truly sanitary pump.
2. Working principle
The core component of the sanitary pump is the impeller, which is usually installed in the pump casing and driven to rotate by a motor. When the motor starts, the impeller starts to rotate at high speed, generating centrifugal force, causing the liquid to be thrown from the center of the impeller to the outer edge of the impeller. This process forms a negative pressure area, so that the external liquid is sucked into the pump body under the action of atmospheric pressure. As the impeller continues to rotate, the liquid is continuously pushed to the outlet pipe of the pump, thus completing the liquid delivery process.
III. Features and Advantages
Sanitary standards: The design of sanitary pumps focuses on sanitary standards and is usually made of food-grade materials, such as stainless steel (AISI 316), to ensure that the fluid is not contaminated during the delivery process. The internal structure of the pump body is smooth, easy to clean and disinfect, and prevents the accumulation of bacteria, mold and other microorganisms.
High efficiency and energy saving: Through advanced design and technology, sanitary pumps effectively reduce energy consumption and save production costs. Its structure is stable and runs smoothly, and it can maintain efficient working conditions for a long time, reduce production line downtime, and improve production efficiency.
Wide applicability: Sanitary pumps are suitable for the delivery of a variety of fluid media, including liquid medicine, beverages, dairy products, corrosive liquids, etc. At the same time, its flow rate, head, power and other parameters can be customized according to specific needs to meet the needs of different application scenarios.
IV. Application areas
Pharmaceutical industry: used to transport liquid medicine, cleaning fluid, etc. to ensure the quality and safety of liquid medicine.
Food industry: used to transport beverages, dairy products, condiments, etc. to ensure the cleanliness and safety of food.
Cosmetics industry: used to transport various cosmetic raw materials and finished products to maintain the hygiene and quality of products.
Biotechnology industry: used to transport biological culture media, fermentation liquids, etc. to ensure the accuracy and safety of biological experiments.
Other fields: also widely used in environmental protection, agriculture and other fields to transport various fluid media.
Sanitary pumps are a type of pump equipment specially designed to meet high hygiene standards, with a wide range of applications and significant advantages. When selecting and using sanitary pumps, comprehensive consideration should be given to the specific application requirements and working environment to ensure their performance and safety.
