The RXB flexible rotor pump is a volumetric pump that vacuum吸取液体 and extrudes it. Since its invention, it has found increasing application in various industrial and mining settings.

Features:

Small size, large flow rate – generally, compared to competitive pump types, the same flow rate has a smaller volume, making it easier to install and move.

Instant full self-priming—no additional equipment required, no need to replenish fluid before operation. Suction range up to 5 meters.

The pump body is precision cast from stainless steel, with all flow-through metal components made of stainless steel (1Cr18Ni9Ti).

Medium conveying viscosity up to 2000 centipoises

Transports gases and foam liquids without airlock.

Capable of conveying media containing suspended 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 the transport of solvents like alcohol, gasoline, acetone, etc. when equipped with explosion-proof motor.

Aesthetically pleasing, durable, and easy to maintain

Application:

The self-priming capability and strong working condition adaptability of this pump make it suitable for various industrial applications, including drum emptying, silo cleaning, liquid suction and discharge from underground pools, sampling, and conveying of fluids and semi-solids. For instance, during drum emptying, simply inserting the inlet hose into the drum allows for complete drainage. It effectively replaces centrifugal self-priming pumps, submersible pumps, gear pumps, and other types of pumps.

Chemical Field - Media including weak inorganic acids, organic acids, alkalis, salts, oils, alcohols, ketones, esters, etc.

Areas with less stringent hygiene requirements

I. Product Introduction:

Flexible Blade Self-Priming Pump, also known as Flexible Rotor Pump, Flexible Rotor Pump, and Flexible Impeller Pump, is a new type of volumetric self-priming pump that vacuum吸取 fluids (no need to fill the pump initially) and compresses the discharge. It boasts both dry self-priming capability and strong conveying power, ideally suited for transporting shear-sensitive, medium to low viscosity materials, and those containing suspended particles. While featuring the stable, pulse-free operation of centrifugal pumps, it can also pump high-viscosity media like rotor 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.

Section II: Working Principle:

① Inside the pump chamber, there is an eccentric bulge. As the flexible blades move away from the eccentric block, the volume between the blades continuously increases, creating a vacuum, which allows the liquid to be continuously吸入 into the pump chamber's inlet.

② As the flexible blades rotate, the liquid is drawn from the suction side of the pump chamber to the discharge side.

③ Upon re-contact with the eccentric boss, the flexible blades bend and are accompanied by a compressing action, ensuring a continuous and pulsation-free discharge of the fluid from the pump chamber, 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 bending and flexing without breaking or tearing. The impeller elastomer technology determines the pump's performance and durability. Currently, there are two materials for the impeller—hydrogenated nitrile rubber and silicone; nitrile impellers are mainly used for oil-containing media such as vegetable oil, mineral oil, gasoline, diesel, and aviation fuel. Silicone is primarily used in the food hygiene industry or for weak acid and weak alkali media.

Four, Product Features:

Small size, high flow rate.

Flow is pulseless.

Non-liquid self-priming. Can reach a height of up to 5 meters of water column.

Can handle fluids and semi-solids with viscosities up to 5,000 centipoise.

Can transport gaseous-liquid, foam liquid without air blockage.

Can handle 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 parts are made of SUS304, AISI 316 stainless steel; pump cavity designed with no dead corners, both inner and outer surfaces polished; meets 3A and GMP standards.

The pump head can be quickly removed and installed for cleaning—even for beginners, it won't take more than five minutes to disassemble and reassemble. It meets CIP on-site cleaning requirements (up to 120 degrees Celsius).

The进出口 can rotate 360 degrees with the pump head to accommodate pipeline connections.

Direction of import/export can be interchanged—simply adjust the motor's direction.

The rotating components inside the pump chamber—flexible impeller—operate without metal contact, ensuring silent operation.

Compared to competitive pump types, low initial investment, maintenance, and operating costs.

V. Product Applications:
