Aulank Chemical Pump Structure & Key Components
The magnetic drive regenerative pump transmits torque through inner and outer magnets without mechanical contact. The motor drives the outer magnet, which couples with the inner magnet to rotate the impeller while fully isolating the pump chamber from the motor. This design eliminates dynamic shaft seals and is suitable for corrosive, volatile, or leakage-critical chemical fluid transfer and circulation.
The magnetic drive centrifugal pump transmits torque via inner and outer magnet coupling, fully isolating the pump chamber from the motor. By eliminating mechanical shaft seals, this design is well suited for corrosive, hazardous, or leakage-critical chemical fluid transfer and continuous circulation applications.
The magnetic drive sealed gear pump combines magnet coupling with a gear pumping mechanism. Torque is transmitted through inner and outer magnets, driving synchronized gears within a sealed chamber. This design provides stable positive displacement and enhanced sealing performance, making it suitable for viscous, metering-critical, and leakage-sensitive chemical fluid transfer applications.
The sealed vane pump uses a positive displacement vane mechanism, where the rotor and vanes generate stable volumetric changes for smooth and continuous fluid transfer. The shaft sealing area is isolated through a sealing structure to reduce leakage risk, making it suitable for stable delivery and circulation of low- to medium-viscosity chemical fluids.

Stable Operation from - 196 °C to +400 °C
Chemical pumps often operate under low-temperature transfer, high-temperature reaction loops, and frequent thermal fluctuations. Through coordinated material systems and structural design, Aulank chemical pumps support a wide temperature range from −196 °C to +400 °C. This Optimize design reduces unplanned downtime in multi-temperature chemical systems.
Chemical Pump Selection Guide
Chemical pump selection should be based on media properties, operating conditions, and system requirements. Clear definition of key parameters at the early stage helps shorten selection time and reduce later adjustments. Key factors to consider: • Media properties (corrosiveness, viscosity, temperature, solids) • Operating temperature and pressure range • Flow rate and head requirements • Pump structure and drive type • Material compatibility and sealing design • Continuous operation and maintenance needs
