When choosing a rotary lobe pump for food processing, the following factors need to be considered: 1. Material: Rotary lobe pumps used for food processing should use stainless steel, because rotor pumps of stainless steel is corrosion resistant and will not cause secondary pollution to food material. 2. Design: Rotary lobe pumps design should be easy to clean and maintain, because it is required to ensure the cleanliness of the equipment during food processing. 3. Performance: The performance of rotary lobe pumps should be able to meet the needs of food processing. For example, if it is used to transport sticky foods, then the rotary lobe pump should have a strong self-priming capacity and transport capacity. 4. Brand and price: Choose a well-known brand of rotary lobe pumps, quality is guaranteed, after-sales service is guaranteed. In terms of price, you had better make a choice according to budget and needs, and do not blindly pursue low prices. 5. Certification: Select rotary lobe pumps that have passed food grade certification to ensure that it meets food safety standards. For example, some rotary lobe pumps are with 3A and FDA certificate. 6. Energy efficiency: Choose a rotary lobe pump with high energy efficiency, which can save energy and reduce production costs.

Cavitation is very harmful to pumps! So, what is cavitation? What are the hazards? Which parts are prone to cavitation? What is cavitation? When the local pressure of the liquid in the pump drops to the critical pressure, bubbles will be generated in the liquid. Cavitation is the entire process of bubble aggregation, movement, splitting, and elimination. The critical pressure is generally close to the vaporization pressure. The hazards of cavitation A. Corrosion of overcurrent components There are two reasons for corrosion: Firstly, due to the high-frequency (600-25000HZ) impact generated by the bursting of bubbles, the pressure reaches up to 49Mpa, resulting in mechanical erosion of the metal surface; Secondly, due to the release of heat during vaporization and the action of a temperature difference battery, hydrolysis occurs, resulting in oxygen oxidation of the metal and chemical corrosion.

Rotary lobe pumps play a very important role in food processing industry. Here are some main roles: Precise delivery: Rotor pumps can accurately transport a certain amount of materials, which is very important for food processing where the ratio of raw materials needs to be precisely controlled. Temperature control: In some food processing processes required to be carried out at a specific temperature, lobe pumps can control the temperature of the materials by conveying cooling or heating materials. Pressure control: Lobe pumps can provide stable pressure, which is very important for food processing processes required to be carried out under a certain pressure. Transferring sticky materials: Rotor pump can effectively convey materials with high viscosity, such as chocolate, jam, bean paste etc. Maintain food quality: The working principle of rotary lobe pump makes the material not easy to shear and impact during conveying, which is conducive to maintaining the food original texture and taste. Health and safety: Food-grade rotary lobe pump design is critical to food safety. Their design and materials meet food safety standards, are easy to clean and disinfect, and can effectively prevent food contamination. Durrex pumps mastered the core key techn

Leakage is one of the common faults that occur in mechanical equipment. There are two main reasons for leakage: firstly, due to the results of mechanical processing, there are inevitably various defects and shape and size deviations on the surface of mechanical products, so gaps will inevitably occur at the joints of mechanical parts; The second is that there is a pressure difference on both sides of the seal, and the working medium leaks through the gap. Reducing or eliminating gaps is the main way to prevent leakage. The function of sealing is to seal the gap between the joint surfaces, isolate or cut off the leakage channel, increase the resistance in the leakage channel, or add small power components in the channel to cause pressure on the leakage, partially o
