During the 47th annual Chem Show, held Nov. 18-20 in New York, N.Y., Liquiflo Equipment Company unveiled a new series of Centry centrifugal pumps and a new Vantage series of positive displacement rotary pumps.

Centry Pumps
Liquiflo is pursuing a patent on the new turbo impeller Centry pumps, which company officials said provide more efficient operating performance than conventional centrifugal pumps.

They are available in three sizes with conventional impellers and two sizes with a high head "Turbo
impeller" and are fabricated in 316 Stainless, Alloy 20 and Alloy C. The flow rates range from 2 GPM (.45 m3/hr) to 120 GPM (27 m3/hr), and operating temperatures range from -60 degrees Fahrenheit to more than 600 degrees Fahrenheit, flanged or threaded.

Efficiencies of up to 70 percent area achieved at a price reduction of 30 percent when compared to ANSI
1 ½ x 1 x 6 pumps. Lower magnetic losses provide annual power savings and longer bearing life in most applications, according to company officials. Applications include transfer, circulation, blending, unloading and heat transfer. Major chemicals that may be processed include sulfuric acid, hydrogen peroxide, isocyanate, methanol chloride and miscellaneous hydrocarbons.

Vantage Pumps
The Vantage series of positive displacement rotary pumps offer high levels pulse-less flow and feature a compact, economical configuration, said a company representative. Liquiflo can now provide positive displacement gear pumps covering a full range of flow rates from .01 gpm (1.2 gph or .05 pm) to 1,000 gpm (4000 lpm).

Vantage pumps feature a wear adjustment system, which compensates for wear on the front of the rotor
by adjusting the axial position of the rotor, and a casing that can be rotated on the bearing housing to take up different positions. The heating chamber is cast integral with the casing or mounted on the cover or gland. In addition, by adjusting the axial position of the rotor, the same pump can handle water thin liquids or high viscosity liquids, and by inverting the direction of the rotation, the flow of liquid is reversed. Full performance is available in either direction of the flow.
