4-blade impeller A620

for agitatorsaxial-flow

Recommended for non-Newtonian transitional flow blending, where Reynolds numbers are between 50 and 500. FEATURES • Optimal two bladed design creates down flow in the center and up flow at the wall, creating a complete turnover of tank's contents • Provides similar blend time for less power than traditional open impellers (A320, A200) and less torque (lower cost) than traditional close clearance impellers (A400, R400) • Operates at high impeller diameter/tank diameter ratios, which improves heat transfer at the wall • Bolted construction available for tanks with small diameter manways
