Vortex Pump

Aulank AYDH liquid nitrogen pump (magnetic vortex pump) adopts a magnetic-drive regenerative pump structure. The assembly consists of the pump cover, regenerative impeller, pump body, shaft sleeve, inner magnet, isolation sleeve, outer magnet, support base, and motor system. Torque is transmitted through magnetic coupling between the inner and outer magnets, fully isolating the drive side from the fluid side and eliminating shaft penetration, which reduces leakage and sealing failure risks in cryogenic conditions. The structure is optimized for liquid nitrogen and other ultra-low-temperature fluids, maintaining stable high-head, low-flow performance at temperatures down to -196°C, making it suitable for cryogenic circulation, low-temperature testing, and safety-critical LN₂ systems.

The Aulank MDP permanent magnet shielded vortex magnetic pump features an integrated permanent magnet drive and shielded structure. The assembly consists of the pump cover, regenerative impeller, pump body, shaft sleeve, spindle, inner magnet, isolation sleeve, and motor system. Torque is transmitted through magnetic coupling between the inner and outer magnets without mechanical contact, fully separating the drive side from the fluid side and eliminating mechanical seals. This design reduces leakage and thermal accumulation risks in high- and low-temperature applications, while the compact, integrated structure enhances stability and makes the pump suitable for high-head, low-flow continuous circulation and precision fluid transfer systems.

The Aulank WL vertical vortex pump (mechanical seal) features a vertical configuration combined with a mechanical sealing structure. The assembly consists of the pump cover, regenerative impeller, sliding bearing, pump body, and motor system. Power is transmitted directly through the motor-driven shaft, while the regenerative impeller generates a stable energy-accumulating flow pattern suitable for high-head, low-flow applications. The mechanical seal provides reliable sealing performance with convenient maintenance access, making the pump suitable for industrial systems requiring cost efficiency, structural simplicity, and long-term stable operation. The vertical design minimizes footprint and supports compact equipment integration.

The Aulank MDH(L) stainless steel magnetic vortex pump features a magnetic-drive regenerative pump structure. The assembly consists of the pump cover, regenerative impeller, spindle, inner and outer magnets, bearing system, drive shaft, coupling, and motor unit. Torque is transmitted through magnetic coupling without mechanical contact, fully isolating the drive side from the fluid side and eliminating seal wear or leakage risks under high- and low-temperature conditions. The regenerative impeller generates a stable energy-accumulating flow pattern, making the pump suitable for high-head, low-flow transfer, gas–liquid mixed operation, and continuous circulation. The stainless steel pump body and multi-stage surface treatment enhance structural stability and fluid compatibility across a wide temperature range from -196°C to +400°C.
