Flexible rotor pump

1、 Product Introduction:

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 (without the need for injection or drainage during initial use), 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 deformation, and be able to withstand long-term high-frequency bending without breaking or tearing. The performance and durability of the pump are determined by the technology of impeller elastomer, which takes ten years to sharpen a sword. 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 performance:
1. Strong self suction force, good structure, dry self suction of 6 meters, with material self suction of 9 meters
2. Short self-priming time, instant self-priming within 6 meters, completed in 2-3 seconds.
3. Simple structure, easy maintenance, no need for personnel guidance, and maintenance does not require dismantling of pump pipelines.
4. Purchase the pump once for lifelong use, with fewer vulnerable parts.
5. Small size, occupying less space for on-site equipment.
6. High efficiency with a large amount of traffic, low power and energy saving under the same traffic.
7. Indoor installation without noise
8. It can transport hard particles containing particulate impurities.
9. The viscosity of the conveying medium can reach 5000 centipoise

5、 Product features:
Small size, high flow rate - Generally speaking, compared to competing pump types, the volume is smaller at the same flow rate. Easy to install and move.
Instantly completely self-priming - no additional devices required, no need to replenish fluids before starting. The suction range can reach up to five meters.
The pump body is made of stainless steel precision casting, and all overcurrent metal components are made of stainless steel (1Cr18Ni9Ti).
The viscosity of the conveying medium can reach 2000 centipoise
It can transport gas-liquid and foam liquid without air lock
Can transport media containing suspended soft and hard particles.
The gentle movement of the rotor does not damage media that are sensitive to shear, such as paper dispersants.
Flexible rotors operate without metal contact and do not generate sparks; Equipped with explosion-proof motors, it is particularly suitable for transporting solvents such as alcohol, gasoline, and acetone.
Beautiful appearance, durable and easy to maintain

6、 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.
