The three-lobe rotor pump is a positive displacement pump. The following is a detailed introduction to it:
The three-lobe rotor pump relies on two synchronously moving rotors, which are driven by a pair of external synchronous gearboxes. The rotors rotate synchronously in opposite directions under the drive of the transmission shaft, thus creating a relatively high vacuum degree and discharge pressure. The two rotors divide the rotor chamber into several small spaces, and they operate in a certain order. When operating at different positions, each small space is respectively in a state of being filled with the medium, sealed with the medium, or communicating with the inlet and outlet, so that the medium can be continuously conveyed out.
Excellent Material: All the spare parts in the pump that come into contact with the conveyed materials are made of stainless steel materials that meet the hygienic standards. Its seals are all made of non-toxic rubber, ensuring safety and hygiene, avoiding pollution to the conveyed substances, and being suitable for on-site CIP cleaning and steam disinfection, fully complying with the requirements of the US FDA regulations and the pharmaceutical grade (GMP) specifications.
Reasonable Design: The streamlined structure of the rotors and the absence of dead spots and non-metallic parts in the rotor chamber can prevent material residue and accumulation, ensuring the purity of the materials and the normal operation of the pump. The external dynamic and static ring mechanical seals are adopted, which can be directly flushed with water, are resistant to high pressure, are not easily worn, and have no leakage.
Superior Performance: It has a small volume, a large flow rate, a high head pressure, and is suitable for quantitative conveying over long distances and with high resistance. The impeller of the pump is separated from the transmission gears, and a certain gap is ensured between each spare part in the pump cavity. They do not contact each other, have no wear, produce low noise, have good reliability, a long service life, and can save energy and reduce consumption. After being equipped with a frequency converter, the flow rate can be adjusted at will, and it can be used as a general metering pump. It can convey three-phase mixed materials such as gas, liquid, and solid, and the viscosity of the conveyable medium can be as high as 1,000,000 cp, and it can convey slurry with a solid content of up to 55%.
Food Industry: Yogurt, fresh cream, ice cream, cheese blocks, whey, beer, malt juice, yeast, jam, syrup, soda, fruit juice, pudding, tomato sauce, sesame paste, peanut butter, condiments, edible oil, whey, etc.
Daily Chemical Industry: Gel, facial cleanser, hand sanitizer, body wash, washing powder, skin care products, hair dye, essential oil, toothpaste, detergent, shampoo, shoe polish, cosmetics, essence, soap, balm, glycerin, fatty acids, etc.
Pharmaceutical Industry: Various types of pills and pastes, emulsifiers, syrups, nutrient solutions, traditional Chinese medicine, pasty drugs, biological products, fish pollen, royal jelly, vaccines, health products, etc.
Chemical Industry: Fat, solvent, resin, polymer, paint, pigment, dye, coating, lubricating oil, grease, petroleum agent, emulsified asphalt, adhesive, plastic, fiberglass, leather, etc.
Construction Industry: Various coatings, including interior and exterior wall coatings, anti-corrosion materials, ceramic coatings, paint coatings, ceramic glazes, etc.
Other Industries: Plastic industry, textile industry, paper-making industry, coal flotation agent, nano materials, biochemical industry, etc.
The three-lobe rotor pump is especially suitable for conveying media that are prone to foaming during the conveying process as well as those with high viscosity, concentration, and containing particles. The materials conveyed by it maintain their original quality unchanged, without any physical or chemical reactions. The conveying flow rate can be controlled relatively accurately, and it can be used as a metering pump.
Shape: The three-lobe rotor has three blades on the rotor. The shape is regular, usually curved, which can better grasp and convey the medium. While the two-lobe rotor has only two blades, and the shape is relatively straight and simple.
Functional Characteristics: Due to having one more blade, the three-lobe rotor can provide a larger pumping flow rate and a higher outlet pressure. The two-lobe rotor is relatively smaller and is suitable for scenarios with smaller flow rates and lower pressure requirements.
Efficiency and Noise: Due to the special design of the blade shape, the three-lobe rotor has higher efficiency and lower noise. The two-lobe rotor has relatively lower efficiency and higher noise due to its relatively simple blade shape.
Applicable Scenarios: The three-lobe rotor is applicable to scenarios in the industrial field that require large flow rate conveyance and high pressure, such as conveying hydraulic oil, fuel oil, etc. The two-lobe rotor is applicable to scenarios with smaller flow rates and lower pressure requirements, such as conveying lubricating oil, coolant, etc.
