FLO KING LAB SERIES PUMP MATERIAL OF CONSTRUCTION

Lab Series MaterialPolypropylene is the standard pump material of construction for the Lab Series. Because this model is used for laboratory, prototype and clean production operations in small tanks up to about 10 gallons (38 liters) — as opposed to large industrial tanks — most of the processes are compatible with polypro.

Typical applications include: nickel electroplating, precious metals plating, copper plating, tin plating, zinc plating, chromating, decorative chrome plating, lower-temperature electroless nickel plating (185 - 190 F, 85 - 89 C), passivating, pickling, rinsing, low-temperature seals, mild alkaline cleaners

Kynar (PVDF) as Pump Material of Construction
Kynar, a higher-temperature plastic than polypro, is occasionally specified for Lab Series pumps used in electroless nickel at about 194 F (90 C) and higher, and in other low- to moderate-pH applications where polypro is unsatisfactory. Kynar is not suitable for caustic solutions.

Kynar is expensive — about 75 percent more than polypro for the Lab Series.

INTERNAL METAL-SHAFT MATERIAL FOR LAB SERIES

Lab Series Shaft MaterialThe Lab Series has an internal shaft made of 303 stainless-steel covered with Teflon heat-shrink tubing. Caution: If using the pump strictly for recirculation (without filter cartridge attached), always install a Pump Strainer Adapter for Lab Series (PSAL) to protect the Impeller, Shaft, and Teflon heat-shrink tubing from damage due to any foreign objects that might be in solution.

OTHER SOURCES OF MATERIAL INFORMATION
There are many Chemical Resistance Charts available on the internet. We encourage you to research those charts for compatibility information if you do not find what you need here.



Lab Series In-Tank Material

Almost all Lab Series customers use polypro as pump material of construction. Kynar (PVDF) is used occasionally for special applications.
