This improves the original production process, enhances the quality of daily chemical products, improves production efficiency, and reduces production costs. Washing product delivery rotary lobe pumps Daily cleaning and washing products include detergents, shampoo, shower gel, laundry detergent and paste, etc. In the production process of washing products, there is a high requirement for the hygiene level of the equipment. The selection of pumps should not only consider stability and reliability, but also consider the needs of CIP cleaning. Durrex rotor pumps, without sanitary dead corners, have high accuracy, smooth operation, and low pulse, which can solve long-distance transportation problems. At the same time, it can cooperate with CIP system cleaning to achieve multiple uses of one pump. Toothpaste lobe pumps The materials that need to be transported in toothpaste production include sorbitol, glycerol, K12, toothpaste paste, etc. Due to the high viscosity of the paste and the presence of calcium carbonate, it is necessary to consider hygiene and material wear resistance when selecting equipment. Durrex sanitary grade rotor pumps can solve the transportation problem of materials in various stages of the toothpaste industry from raw materials to finished product filling, especially the narrow face machine seal developed by Durrex pumps, which can withstand large pressure to solve the problem of machine seal leakage. Cosmetic rotor pumps The media to be transported in cosmetics production include glycerin, carbomer, Hansen, hyaluronic acid, thickener, lotion, cream, etc. The entire production process is carried out in a clean workshop, with special requirements for equipment structure, hygiene level, and cleaning system. Durrex rotor pumps have obtained certifications such as 3A, FDA, CE, etc., meeting food hygiene requirements, and supporting CIP system cleaning. According to the viscosity of different media, different speed configurations are adopted to meet the production process requirements of various cosmetics. Surfactant transfer lobe pumps Surfactants include sulfonic acid, AES, AOS, MES, etc. Temperature changes have a significant impact on their viscosity during production and transportation, and their high acidity can cause serious corrosion to equipment. Therefore, professional application technology and experience are required in equipment speed, material selection, and design. Durrex rotor pumps adopt different speed configurations and insulation devices based on the characteristics of non-Newtonian fluids. At the same time, based on years of practical experience, a special structural mechanical seal has been developed to improve conveying efficiency and extend service life. Soap transfer rotary lobe pumps The transportation media in the soap production process include liquid alkali, fatty acids, soap base, waste soap, etc., which have strong corrosiveness, high temperature and concentration, high output pressure, and high sealing requirements during the production process. In response to this special working condition, Durrex introduced rotor pumps with water circulation cooling and sealing configuration, which, in conjunction with Durrex neutralization and mixing pumps, can achieve online homogenization and mixing, and improve product quality. Detergent slurry homogeneous pumps Laundry powder slurry contains various media such as surfactants, phosphates, alkaloids, sodium sulfate, fluorescent agents, enzymes, etc. It is mixed and sprayed to form a powder. The traditional process is to use a high-pressure pump to deliver the powder to the powder spraying tower. During the powder spraying process, there is often a phenomenon of nozzle blockage, resulting in uneven powder color and inconsistent product quality in different batches. Durrex homogeneous pumps thoroughly mix and disperse the slurry before powder spraying, effectively solving the problem of powder blockage and improving product quality. Washing liquid homogeneous pumps The main components of laundry detergent include surfactant, thickener, preservative, essence, pigment, water, etc. In the traditional production process, the preservative is first added to the water and stirred, then other raw materials are gradually added, and the thickener is added after mixing.
