Flexible pump

Details

Flexible blade self-priming pump, abbreviated as flexible pump, is also known as flexible rotor pump, flexible rotor pump, or flexible impeller pump based on its working principle and structural characteristics. Flexible blade self-priming pump is a new type of volumetric self-priming pump for vacuum suction (first use without the need for injection and drainage), extrusion and drainage. It has first-class dry self-priming ability and strong conveying ability, and can ideally transport materials that are sensitive to shear, have low to medium viscosity, and contain suspended particles. With the stable and pulse free characteristics of centrifugal pumps, it can also transport high viscosity media like rotary pumps, gear pumps, and other volumetric pumps. The rubber impeller does not generate sparks during operation, and when paired with an explosion-proof motor, it can transport flammable and explosive dangerous goods, truly achieving zero safety hazards. Since its invention over twenty years ago, it has been increasingly widely used in various industrial and mining settings.
2、 Working principle:
① There is an eccentric protrusion in the pump chamber. When the flexible blades leave the eccentric protrusion, the volume between the blades continuously increases, creating a vacuum that allows the liquid to be continuously drawn into the inlet of the pump chamber.
② When the flexible blades rotate, the liquid is carried into the discharge section from the suction part of the pump chamber.
③ When the flexible blade comes into contact with the eccentric protrusion again, it bends and undergoes a squeezing action, causing the liquid to be continuously and non pulsating discharged from the pump chamber, thus completing the entire suction and discharge process
3、 Flexible elastomer technology:
As the core technology of flexible pumps, the impeller of the pump should have good elasticity, minimal permanent deformation, and be able to withstand long-term high-frequency bending without breaking or tearing. The excellent impeller elastomer technology determines the outstanding performance and durability of this pump, which has been honed in ten years. There are two materials for the impeller: hydrogenated nitrile and silicone; Dingqing impeller is mainly used for oily media such as vegetable oil, mineral oil, gasoline, diesel, aviation kerosene, etc. Silicone is mainly used in the food, pharmaceutical and hygiene industries or weak acid and weak base media
4、 Product features:
Small size, high flow rate.
The liquid flow has no pulsation.
The highest self-priming without liquid can reach up to five meters of water column.
Can handle fluids and semi fluids with an absolute viscosity of up to 5000 centipoise.
It can transport liquid containing gas, liquid and foam without air lock.
It can transport suspended hard and soft granular media without damaging the pump and media.
The gentle movement of the pump does not damage the shear sensitive and shake soluble media.
All overcurrent metal components are made of SUS304 and AISI316 stainless steel; Specially designed pump chamber with no dead corners and polished inner and outer surfaces; Compliant with 3A and GMP standards.
The pump head can be quickly disassembled and installed for cleaning (with the shortest downtime) - even for beginners, the disassembly process will not take more than five minutes. Meets CIP on-site cleaning (up to 120 degrees Celsius).
The import and export can rotate 360 degrees with the pump head to adapt to pipeline connections.
The import and export directions can be interchanged - simply adjust the motor direction.
The only rotating component in the pump chamber - the flexible impeller - operates without metal contact, resulting in silent operation.
Compared with competitive pump types, it has smaller investment, lower maintenance and usage costs.
5、 Product application:
Chemical industry - a wide range of media including weak inorganic acids, organic acids, bases, salts, oils, alcohols, ketones, esters, etc.
The food industry, which does not have very strict hygiene requirements, is used to transport edible or nutritional fluids and semi fluids (containing suspended soft and hard particles, with different viscosities, fragile, absolutely non emulsifiable), such as pasta, jam, eggs, tomato sauce, salt water, seasonings, edible oil, canned food, pasta, jelly, milk, ice cream, yogurt and fruit pellet yogurt, whey, syrup, honey, glucose, tomato juice and pulp, beer, wine, grape juice, grape juice with stems removed, soft drinks, fruit pulp, concentrated fruit juice.
Daily chemical industry cosmetics lotion, bath liquid, shampoo, soap liquid, detergent, toothpaste.
Medicine - syrup, starch syrup, traditional Chinese medicine preparations, nutrient solution, cod liver oil, royal jelly.
