Rxb Flexible Impeller Rotor Pump

A robust flexible-impeller (flexible rotor) pump designed for industrial liquid transfer where gentle handling, self-priming and the ability to pass suspended solids are required. This positive-displacement pump combines the steady, low-pulsation flow of a rotary pump with self-priming vacuum capability, making it suitable for a wide range of viscous and particulate-bearing fluids.

Key features

• Positive-displacement flexible-impeller design: provides smooth, pulse-free flow and good suction performance for self-priming and dry-start conditions.
• Handles a wide range of viscosities and media containing suspended solids, fragile particles or soft particulates without damaging the product.
• Non-sparking rubber impeller: reduces ignition risk when handling flammable liquids; compatible with explosion-proof motor installations for hazardous-area service.
• Two impeller material options: hydrogenated butylene (recommended for oils and hydrocarbon fuels) and silicone (suitable for food, pharmaceutical and mild-acid applications).
• Broad chemical compatibility: suitable for weak inorganic acids and alkalis, salts, oils, alcohols, ketones and esters depending on construction/materials.

Typical applications

• Food & beverage: sauces, jams, jellies, fruit pulps, yogurt, whey, glucose syrups, honey, juices and concentrated fruit products.
• Pharmaceutical & nutraceutical: syrups, nutrient solutions, fish-liver oil, royal jelly and other sensitive liquids.
• Chemical processing: transfer of oils, solvents and a variety of low-to-medium viscosity chemical liquids.
• Personal care & household products: shampoos, lotions, soaps, detergents and toothpaste.

Impeller material guidance

• Hydrogenated butylene impeller: best for vegetable oils, mineral oils, gasoline, diesel and kerosene and other hydrocarbon-based media.
• Silicone (silica gel) impeller: selected for food-grade, pharmaceutical or mildly acidic media where product compatibility and hygiene are priorities.

Benefits for B2B buyers

• Versatile: suitable for production, transfer and packaging lines across food, pharmaceutical, chemical and cosmetics industries.
• Gentle pumping action reduces product degradation for shear-sensitive fluids.
• Easy to specify by selecting the appropriate impeller material and motor/explosion-proof options for safe use with flammable media.

For quoting and specification, provide the required flow rate, discharge pressure (head), fluid characteristics (viscosity, temperature, solids content and particle size) and preferred impeller material so the correct model and materials of construction can be selected.
