JET-STIR IMPELLER Model 1117 (S/w/l Det~eloJme~tt Co. Design)

Patent No. 2,8 16,744

Th e problem of minimizing temperature gradients in baths has been solved with the Jet-Stir Impeller,

a development of the Shell Development Co. Excellent stirring is essential in maintaining temperature

changer at a minimum and in reducing the amount of time it taker for a heat change to be recorded.

The Jet-Stir Impeller combines centrifugal pump action with a pitched blade propeller. The result

is greatly increased stirring efficiency. All the available horsepower in a stirring motor is now convertible

to energetic random motion of the liquid being stirred. The bl a es are no longer than the less efficient d

propeller blades usually used. The blades and pump both lift upward and thus lessen the possibility of

a vortex being formed and air drawn into the bath solution.

MATERIALS Jet-Stir Impellers are manufactured of stainless steel as standard. Other materials can be supplied

on special order.
