HRXB Flexible Rotor Pump
1. Product Performance
- Strong suction capability, perfect structural principle: Achieves dry suction up to 6 meters and wet suction (material suction) up to 9 meters.
- Efficient processing: Short suction time (instant suction within 6 meters, completed within 2-3 seconds).
- Simple structure, easy maintenance: No need for disassembly during routine maintenance; does not require complex guiding systems.
- Purchase once, lifelong use: Few consumable parts, small size, saving on-site equipment space.
- Energy-saving and efficient: The smallest power consumption for large flow and high-efficiency energy saving under the same flow.
- No blockage during operation: Can transport hard particles containing granular impurities.
- Wide medium viscosity range: Can handle viscosities up to 50,000 centipoise (50000 mPa·s).
- Strong self-priming ability: Perfect structural principle ensures excellent self-priming performance.
2. Working Principle
There is an eccentric block in the pump cavity. When the flexible blade leaves the eccentric block, the volume between the blades continuously increases, creating a vacuum that continuously sucks the liquid into the pump cavity. When the flexible blade rotates to the eccentric block again, the volume between the blades decreases, and the liquid is continuously pushed out from the pump cavity to the discharge outlet. The suction and discharge processes are completed in this way. As the core technology of the flexible pump, the flexible blade has good elasticity, small deformation, and can withstand long-term high-speed operation without breaking or cracking. “Ten years of磨耗 (wear)” – the blade’s wear resistance determines the pump’s performance and durability. The flexible blade is mainly made of two types of rubber: nitrile rubber and EPDM rubber, which are mainly used for plant oils, mineral oils, oil fractions, and media with higher requirements. EPDM rubber is mainly used for weak acid, alkali, salt, and污水 (wastewater) environments.
3. Product Characteristics
- Small size, large flow: Compared with competitive pumps, it achieves the same flow with a smaller volume, making it easy to install and move.
- Instant self-priming without additional devices: No need to refill before starting; can be started directly after five minutes of shutdown.
- All flow-passing parts are made of stainless steel (1Cr18Ni9Ti): No dead corners in the pump body, ensuring no accumulation of medium; can transport suspended liquids with gas, foam, and gas-liquid mixtures; can also transport soft and hard granular media, and is sensitive to shear.
- The flexible rotor operates without metal contact: No spark is generated, making it suitable for flammable and explosive environments such as oil tanks and chemical solvent transportation.
- Beautiful appearance, durable, and easy to maintain: Flexible rotor pumps do not produce sparks during operation and are particularly suitable for delivering alcohol, gasoline, acetone, and other solvent media. They have a beautiful appearance, are durable, and easy to maintain.
