The RXB flexible rotor pump is a volumetric pump that vacuum-suctions and extrudes fluids. Since its invention, it has gained increasingly widespread application in various industrial and mining settings.
Features:
Small size, large flow rate – generally, compared to competitive pump types, the same flow rate requires a smaller volume. Easy to install and move.
Instant full self-priming – no additional equipment required, no need to add fluid before operation. Suction range up to 5 meters.
The pump housing is precision cast from stainless steel, and all metal components in the flow path are made of stainless steel (1Cr18Ni9Ti).
Medium flow viscosity up to 2,000 centistokes
No air blockage during the transportation of gas-liquid, foam liquid.
Can transport suspensions containing both soft and hard particles.
The gentle movement of the rotor does not damage media sensitive to shearing, such as papermaking dispersants.
Flexible rotor operates without metal contact, no sparks generated; especially suitable for conveying alcohols, gasoline, acetone, and other solvents after explosion-proof motor fitting.
Attractive appearance, durable, and easy to maintain
Application:
The pump's self-priming capability and strong operational adaptability make it suitable for various industrial applications, including drum emptying, silo cleaning, liquid suction and discharge from underground pools, sampling, and conveying a variety of fluids and semi-solids. For instance, when emptying drums, simply inserting the inlet hose into the drum is enough to completely remove the contents. It effectively replaces centrifugal self-priming pumps, submersible pumps, gear pumps, and other types of pumps.
Chemical Industry - Media including weak inorganic acids, organic acids, bases, salts, oils, alcohols, ketones, esters, etc.
Aren't very stringent in terms of sanitation requirements
I. Product Introduction:
Flexible Blade Self-Priming Pump, also known as Flexible Rotor Pump, Flexible Rotor Pump, or Flexible Impeller Pump, is a new type of volumetric self-priming pump that uses vacuum suction (no need for initial fluid filling) and squeezing to discharge liquid. It boasts both dry self-priming and strong conveying capabilities, ideal for transporting shear-sensitive, medium to low viscosity materials with suspended particles. It combines the stable, pulse-free characteristics of centrifugal pumps with the ability to handle high viscosity media like rotor pumps and gear pumps. The rubber impeller operates without sparking, and when paired with an explosion-proof motor, it can safely convey flammable and explosive hazardous materials, ensuring zero safety hazards.
II. Working Principle:
① The pump cavity contains an eccentric boss. As the flexible blades depart from the eccentric boss, the volume between the blades continuously increases, creating a vacuum that continuously draws the liquid into the pump cavity.
② As the flexible blades rotate, the liquid is drawn from the pump's intake chamber into the discharge chamber.
③ Upon re-contact with the eccentric boss, the flexible blade bends, accompanied by a compressive motion, allowing the fluid to be discharged from the pump chamber continuously and pulselessly, thereby completing the entire suction and discharge process.
Section 3: Flexible Elastomer Technology
As the core technology of the flexible pump, the impeller should possess elasticity, minimal deformation, and be able to withstand long-term flexing without breaking or tearing. The technology of the impeller elastomer determines the pump's performance and durability. Currently, there are two materials for the impeller - nitrile rubber and silicone; nitrile impellers are mainly used for oil-containing media such as vegetable oil, mineral oil, gasoline, diesel, aviation kerosene, etc. Silicone is primarily used in the food hygiene industry or for weak acid and weak alkali media.
IV. Product Features:
Small size, large flow.
Flow is pulseless.
Dry vacuum, capable of lifting up to 5 meters of water column.
Capable of handling fluids and semi-solids with a viscosity of up to 5,000 centipoise.
Can handle gaseous-liquid, foam liquids without air blockage.
Can transport suspended hard and soft particle media without damaging the pump or the medium.
The pump's gentle action does not damage shear-sensitive and thixotropic media.
All overflow metal components are made of SUS304, AISI 316 stainless steel; pump cavity designed with no dead corners, both inner and outer surfaces polished; complies with 3A and GMP standards.
The pump head can be quickly dismantled and installed for cleaning – even for beginners, it won't take more than five minutes to disassemble and reassemble once. Satisfies CIP in situ cleaning (up to 120 degrees Celsius).
The进出口 can rotate 360 degrees with the pump head to accommodate pipeline connections.
Import/export directions can be interchanged—simply adjust the motor's direction.
The rotating components within the pump chamber – the flexible impeller – operate without metal contact, ensuring silent operation.
Compared to competitive pump types, lower initial investment, maintenance, and operating costs.
V. Product Applications:
Chemical Industry - Media for weak inorganic acids, organic acids, bases, salts, oils, alcohols, ketones, esters, etc.
Food industry with moderate hygiene requirements — for conveying edible or nutritional fluids and semi-solids (including suspended soft and hard particles, with varying viscosities, fragile, non-foamable), such as batter, jam, eggs, ketchup, brine, condiments, edible oils, canned foods, paste, jelly, milk, ice cream, yogurt and fruit yogurt, whey, syrup, honey, glucose, tomato juice and paste, beer, wine, grape juice, stemmed grapes, soft drinks, fruit pulps, concentrated fruit juices.
