EMISSION SPECTROSCOPY—SYMPOSIUM O N THE STUDY O F SEGREGATION BY ANALYTICAL METHODS Thursday Morning—Pittsburgh Room
SIGMAMOTOR PUMP Move Corrosive Liquids Material being pumped never comes in contact with pump mechanism. W a v e like motion of steel fingers forces m a t e r i a l t h r o u g h Tygon tubing. By changing size of tubing, capacity can be increased or decreased. Pump housing opens f o r removal and insertion of tubing.
J. K. Hurwitz, Presiding
Pump 2 or 3 Different Liquids Simultaneously
SPECTROSCOPY SOCIETY OF PITTSBURGH 1 9 5 9 A W A R D ADDRESS Thurs., March 5 — 8 : 4 5 A . M .
Some models w i l l accommo date up to four tubes so that four different liquids can be passed through the pump at one time without danger of contamination.

Feed and Mix One or more tubes can be feeding material to a mix while a larger tube is recir culating the liquid to pro duce agitation and thorough mixing. Viscous materials can be p u m p e d w i t h o u t danger of gumming or plug g i n g . Remove t u b e a n d pump is clean.
Meter Additives
(Symposium Organized b y the Coblentz Society)
One or more additives can be pumped to a solution in the exact amount desired by selecting the correct size of t u b i n g a n d r e g u l a t i n g pump speed. Various con trols can be incorporated to close valves ahead of pump.
