Applications

Widely used in petroleum, chemical, alkali production, metallurgy, rare earth, agriculture, dyeing, pharmaceuticals, papermaking, electroplating, electrolysis, radio, foil production, research institutions, defense industries, and other production processes for conveying corrosive liquids. Particularly suitable for transporting flammable, explosive, volatile, toxic, high-temperature, strong alkali, organic solvent, and valuable liquids.

Conditions

  • Design pressure: 1.6-6.4Mpa
  • Flow rate: 2-20m³/h
  • Head: 20-135m
  • Power: 1.1-11kW
  • Operating Temperature: -30 to 120°C, with new materials capable of withstanding temperatures from -20 to 350°C.

Features

  • Premium Materials for Flow Components: Pump body, impeller, pump cover, isolation sleeve, and pump shaft are precision-cast from materials such as 304, 316, 316L, 904, TA2, and HC276.
  • Robust Modular Design: The pump body and cover undergo modular design and precision casting, capable of withstanding high-speed, high-pressure liquid flushing and instantaneous thermal shock. It boasts high cavitation resistance, precise dimensions, smooth flow channels, excellent interchangeability, ensuring corrosion resistance and pressure resistance.
  • Efficient Impeller Design: The impeller, designed and cast modularly, ensures reliable torque transmission. Its closed structure, optimized flow channel design, high efficiency, low NPSHR value, and excellent interchangeability guarantee stable pump flow and head.
  • Isolation Sleeve Technology: Utilizing materials like 316L, TA2, HC276, and low-eddy current sleeve design, the isolation sleeve operates within a sinusoidally alternating magnetic field. It induces eddy currents on a plane perpendicular to the magnetic lines and converts them into heat. Optional non-metallic materials with high resistivity and strength effectively reduce eddy currents, eliminating excess heat and reducing energy consumption. With high burst pressure resistance and high safety factor, it completely isolates the pump chamber from the external environment, ensuring a leak-free delivery process.
  • High-Performance Wear-Resistant Materials: The dynamic ring, shaft sleeve, and sliding bearings utilize highly wear-resistant and temperature-resistant materials like crystalline silicon carbide and tungsten carbide. They offer high strength, excellent wear resistance, good adaptability, and strong corrosion resistance, ensuring prolonged pump lifespan.
  • Advanced Magnetic Block: The magnetic blocks are made of Samarium Cobalt 2:17, with a magnetic energy product of 28 Mega Gauss Oersteds and a maximum temperature tolerance of 350°C, minimizing demagnetization and providing a theoretical service life of up to 20 years.
