Selecting Aulank Pump Architecture by Temperature, Viscosity and Media

Pump selection across Aulank vortex (MDW, MDH, AYDH, PWH), centrifugal (AMC, LMZ, CPS, WRY-H, RGP), and positive displacement (MDC, PVP) series depends on fluid viscosity, operating temperature (-196 °C to +400 °C), head pressure, and zero-leakage containment requirements.

For high-head, low-flow TCU, chiller, and semiconductor loops, sealless MDW (up to 220 m head, reversible) and MDH(L) vortex pumps prevent seal wear.

Cryogenic liquid nitrogen duties use AYDH down to -196 °C, hot thermal oil systems rely on air-cooled WRY-H (up to +350 °C) or MDW/MDH (+400 °C), and high-viscosity dosing uses pulse-free MDC-M/X/K gear pumps.
