Aulank Chemical Pumps Operate Reliably from -196°C to 400°C in Chemical Processing Applications

Aulank Pump's chemical pump series operates across a wide temperature range from -196°C to 400°C, handling fluid transfer in chemical processes under extreme thermal conditions. This temperature capability comes from coordinated material systems and structural design, covering applications from cryogenic liquid nitrogen transfer to high-temperature thermal oil circulation.

Core Technical Elements for Wide Temperature Range Operations

Chemical pumps handle corrosive media, thermal fluctuations, and continuous duty cycles in process applications. Aulank chemical pumps use engineering-grade materials including ceramic, PEEK, PPS, and Hastelloy alloys in isolation sleeves, impellers, and pump bodies, achieving zero-leakage performance while maintaining thermal stability.

At cryogenic temperatures down to -196°C, the pump structure reduces self-generated heat and addresses metal contraction issues through specialized design features. This supports reliable transfer of liquid nitrogen and other cryogenic fluids. At the high end, pumps operating at 400°C use custom magnetic materials that maintain coupling stability under sustained thermal stress, serving thermal oil loops and high-temperature chemical reactions.

Flow channel surfaces are polished to Ra 0.2 precision through synchronous permanent magnet technology, preventing metal ion precipitation in high-purity fluid streams. The shielded vortex design combines canned centrifugal pump sealing with vortex hydraulics, reducing footprint while delivering high head at moderate flow rates.

Product Range and Representative Models

Aulank's chemical pump line includes vortex pumps, centrifugal pumps, and positive displacement pumps, with 26 models covering different flow rates, head requirements, and media characteristics.

Vortex Pump series covers three drive configurations. Magnetic Drive Vortex Pumps include the MDH, MDS, MDK, MDW models and the AYDH Magnetic Drive Liquid Nitrogen Pump. Canned Vortex Pumps include the MDP Permanent Magnet Canned Motor Vortex Pump, PWH, PWD, and PWM Canned Motor Vortex Pumps. Mechanical Seal Vortex Pumps include the WH, WK High Head, WD, WD-W, WL Vertical, and WM models.

Centrifugal Pump series includes Magnetic Drive Centrifugal Pumps such as the AMC(L) Chemical Magnetic Drive Pump, AMC-F Chemical Fluorine-Lined Magnetic Drive Pump, and LMZ Centrifugal Magnetic Drive Pump. Mechanical Seal Centrifugal Pumps include the RGP High Flow, RGZ, CPS(L), and WRY-H Coupled High Temperature Thermal Oil Pump.

Positive Displacement Pump series includes Gear Pumps in MDC-X, MDC-M, and MDC-K models, along with the (P)VP High Pressure Vane Pump.

Primary Applications

Aulank chemical pumps serve applications across inorganic and organic chemical raw materials, polymer synthesis, fine chemicals, water treatment chemicals, industrial gases, adhesives, new energy materials, liquid-cooled charging infrastructure, and industrial temperature control equipment. In chemical manufacturing, these pumps handle sulfuric acid, hydrochloric acid, sodium hydroxide, and other corrosive media. In the energy sector, they support lithium battery material processing and hydrogen-related fluid loops. Temperature control systems use these pumps for chiller circulation, mold temperature controllers, and TCU systems.

Engineering Material Applications

Material selection directly affects pump life in corrosive media and thermal extremes. Aulank uses ceramic, PEEK, and Hastelloy in isolation sleeves; PPS and PEEK for impellers; PPS engineering plastics and stainless steel for pump bodies; and 42CrMo steel gears with ceramic bearings in drive components. These materials are matched to structural design for corrosion resistance and thermal stability.

Technical Features and Performance

Synchronous permanent magnet technology provides flow channel polishing to Ra 0.2 precision, eliminating metal ion precipitation risk. High pressure structural design follows API-standard-like construction for petrochemical applications. Ultra high temperature 400°C capability is achieved through custom high-temperature magnetic materials that maintain stable media transfer. The -196°C ultra-low temperature design uses specialized structure to reduce operating heat generation and address metal deformation under cryogenic conditions. Multi-frequency efficiency technology enhances variable frequency operation to optimize energy efficiency and thermal performance while reducing installation footprint. Shielding vortex technology combines canned centrifugal pump sealing with vortex pump hydraulics, saving space while achieving high head and medium-to-low flow performance. Additional features include dry-run frictionless technology for specialized application requirements, spiral gear technology for improved pump efficiency and service life, negative pressure self-priming for stable transfer under high negative pressure and low NPSH conditions, and gas-liquid mixed transportation design for complex gas-dissolving and ozone applications with full leak prevention.
