What Is a Sanitary Pump?
A sanitary pump is a specialized pump used to ensure quality and sanitation.
They are used in a wide range of industries such as food, pharmaceuticals, cosmetics, and bioengineering. This is because micro-contamination or foreign matter in the manufacturing process of food, pharmaceuticals, and other products can have a negative impact on product safety and quality.
Uses of Sanitary Pumps
1. Food Industry
Food production lines require high standards of sanitation. Sanitary pumps are used during the transfer and processing of food products to prevent contamination and foreign matter from entering the food while maintaining food quality. They can be used in a variety of food processing applications, from the transfer of liquids to the transfer of paste-like materials.
2. Pharmaceutical Industry
Pharmaceutical production processes require high quality and hygiene standards. Sanitary pumps are used for mixing, transferring, and filling pharmaceutical solutions to ensure product safety and quality.
3. Cosmetics Industry
Product quality and sanitation are also very important in the production of cosmetics. Sanitary pumps are used for mixing and filling cosmetic ingredients to ensure product uniformity and hygiene.
4. Biotechnology
In biotechnology and bioengineering, microorganisms and cells are cultured, separated, and concentrated. Sanitary pumps enable fine manipulation in these processes and support high quality production.
5. Soft Drink Industry
The production of soft drinks also requires product quality and safety. Sanitary pumps are used for mixing and transferring raw materials and for filling operations in bottling lines.
6. Dairy Industry
High hygiene standards are required in the production of dairy products. Sanitary pumps are used in dairy processing and filling operations to maintain product freshness and quality.
Principle of Sanitary Pumps
1. Design and Materials
Sanitary pumps are specifically designed to meet high sanitary standards. By minimizing internal gaps and grooves, microorganisms and foreign matter are prevented from adhering to the product. In addition, appropriate materials are used to maintain the hygienic properties of products such as food and pharmaceuticals. Chemical resistance, abrasion resistance, and heat resistance are important factors.
2. Suction and Discharge
A sanitary pump has two connections, one on the suction side and one on the discharge side. The operation of the pump draws liquid from the suction side, compresses it inside the pump, and sends it to the discharge side. This action generally utilizes a rotary motion, and the rotating parts are equipped with seals and bearings.
3. Closed System
Sanitary pumps transfer liquid in a closed system, preventing external contamination or foreign matter from entering the system. This is important for maintaining product quality and ensuring hygiene. Clearances inside the pump and ease of cleaning are also taken into consideration in the design.
4. Cleaning and Maintenance
Sanitary pumps require regular cleaning and maintenance to maintain sanitary standards. The pumps are designed to allow for effective cleaning without residue buildup inside the pump. Ease of disassembly and assembly is also important.
5. Compliance With Sanitary Standards
Sanitary pumps are designed to comply with international sanitary standards. Because they are used in industrial fields such as food and pharmaceuticals, they comply with standards such as GMP (Good Manufacturing Practice) to ensure product quality and hygiene.
Types of Sanitary Pumps
1. Drum Pump
Drum pumps are used to transfer small volumes of liquids efficiently. They are suitable for transferring food and chemicals, and are small and easy to handle. Models with different pump head shapes and materials are available.
2. Diaphragm Pump
A diaphragm pump transfers liquid through a membrane (diaphragm) without direct contact with the pump body. It is widely used in fields where hygiene is important. They are suitable for transferring food and pharmaceutical products and are available in a choice of different membrane materials.
3. Syringe Pump
Syringe pumps are used to transfer minute amounts of liquid accurately. Liquid is drawn into a syringe (syringe-like part) and ejected with precise control. These pumps are widely used in the fields of bioengineering and medicine.
4. Rotary Lobe Pump
Rotary lobe pumps are designed to transfer liquids with high efficiency. It is used for transferring food and cosmetics, and has the characteristic of smooth liquid delivery. Multiple lobes rotate to suction and discharge liquids.
5. Centrifugal Pump
Centrifugal pumps are used to pump liquid outward by centrifugal force through high-speed rotation. They are used in the food and pharmaceutical industries as well as in soft drinks. Models are available for different flow rates and pressures.
