What Is Sanitary Pump?

Overview of sanitary pumps


Sanitary pumps are the classification of pumps from the occasion of use of the pumps, specifically involving the transportation of all products that come into contact with the human body, such as pharmaceuticals, dairy products, beverages, food, cosmetics, food additives, fine chemicals, etc. There are four basic types of sanitary pumps, centrifugal, volumetric, jet and air. Centrifugal pumps apply centrifugal force to produce speed, use rotating impellers to increase speed, and push fluid through the outlet valve.


Judging from the material of the pump, the sanitary pump must be 316L stainless steel. There is no sanitary dead corner in the pump cavity, CIP can be cleaned online. The sealing material is food grade material, such as nitrile rubber, fluoro rubber, ethylene propylene rubber, teflon, etc.


From the perspective of the types of pumps, centrifugal pumps, rotor pumps, self-priming pumps, shear pumps, screw pumps, etc., as long as they meet the above requirements, they all can be called sanitary pumps. The impeller of the centrifugal pump must be an open impeller to be a sanitary pump in the true sense.


From the perspective of industry standards, sanitary pumps must obtain US 3A and European EHEDG certification, and the materials meet FDA standards.


This series of pumps is a single-suction, single-stage, centrifugal sanitary pump, suitable for conveying various types of liquids such as milk and wine. It is an indispensable conveying equipment for food, chemical and pharmaceutical industries. The maximum temperature of single seal is about 120 degrees, and the maximum temperature of double seal is 150 degrees. Among them, the high-lift pump is especially suitable for applications in systems with large resistance such as tube sterilization, yogurt temperature holding equipment, and CIP cleaning.


Sanitary pump, also known as centrifugal beverage pump, milk pump, stainless steel beverage pump, which is suitable for conveying milk and other colloidal liquid foods. The maximum temperature for sucking materials is 70-80 ℃. This pump is single-suction fully enclosed. Centrifugal pump.


Sanitary pump--product use


Sanitary pumps usually require liquid during processing to ensure that the food processing industry meets hygienic standards. Types include centrifugal, bucket, container, flexible impeller, rotor pump, sanitary pump. Depending on the type of sanitary pump, it can be liquid mixing, transferring, unloading and handling. Similarly, high-pressure pumps can be used to clean food processing equipment in compliance with hygiene standards, such as pumping peanut butter, pickles, mashed potatoes, red sausages, chocolate, and hops.


Working principle and performance of sanitary pump


The sanitary pump must pay attention to improving the reliability and life of the electric pump, pay attention to the appearance quality of the submersible electric pump and gradually enter the international market. China's submersible electric pumps have obvious competitive advantages in the international market. In particular, it is necessary to improve the appearance quality of submersible electric pumps and give users a sense of beauty, so that domestic-made submersible electric pumps can enter the international market as soon as possible. Therefore, the submersible electric pump itself and the pumping station using submersible electric pump have many advantages. In the future, China's demand will continue to grow, and has the following main development trends.


1. Development of large and medium-sized submersible electric pumps.

Large and medium-sized submersible electric pumps have the outstanding advantages of simplifying the pump structure and saving the investment in the construction of pumping stations. It will be more and more widely used in municipal, industrial and mining, environmental protection and industrial and agricultural water supply and drainage. It is expected that the future demand will be larger. Such as pumps with cutting devices, multi-stage pumps, submersible electric pumps for pumping corrosive media, etc., are still rarely produced.


2. Development of multi-function and multi-purpose submersible electric pumps.

The form of submersible electric pumps in China is not enough compared with the products of famous overseas submersible electric pump manufacturers. However, its market demand is very large, so it has a very good development prospect using two single-end mechanical seals.


3. Development of high reliability mechanical seals.

Mechanical seals are the key part of submersible electric pumps. In this way, the pressure of the medium can act on the end face, and the leakage direction is inward flow type, which is advantageous but the structure is slightly more complicated. The double end face mechanical seal is installed in the oil chamber. The end faces on both sides should adopt different structural styles, so that the pressure of the medium can act on the lower end face. Otherwise, only the spring force will cause the reverse thrust of the seal end face to easily open the end face. Therefore, further research should be conducted on the structure and data to improve its reliability and life. All these data should be applied to the submersible pump as soon as possible.


4. New materials, new technologies and new technologies will gradually apply ordinary pumps.


Stainless steel and fluoroplastics (F46 lined plastic, rubber lined, sprayed ceramics, etc.) have been used. It will expand the application field of submersible pumps, computer-aided design, auxiliary manufacturing and auxiliary testing. The application of new technologies and new processes is also imperative. Facts have proved that the application of new technologies, new materials and new processes related to sanitary pumps can not only improve labor productivity, but also ensure stable and reliable product quality.
