Dry Run Capability
Standard Dryguard Silicon
Provide the corrosion resistance and
durability of silicon carbide with short
term dry run capability without the
catastrophic failuremodes of standard
silicon carbide in a dry run situation.
Standard large internal clearances allow
the passage of solids up to 0.06 inches
with a maximum concentration of 2%.
With the optional clean external injection
flush, the 3299 can handle solids up to
0.080 inches with a concentration near 10%.
PFA Construction for Universal Corrosion Resistance to 360°F (182°C)
Virgin Teflon® (PFA) is virtually inert to all chemicals and has good abrasion resistance. PFA lined casing, bearing carrier, containment shell, and one-piece impeller/shaft assembly provide superior corrosion resistance and long life, unequalled by alloy pumps.
Designed for Safe Operation
Dual Containment Shell
PTFE lining with carbon fiber reinforced plastic (CFRP)
shell. Non-metallic construction provides efficiencies the same or better than sealed ANSI pumps; 30% higher efficiencies than metal sealless pumps.
Non-metallic construction eliminates magnet losses and heat generation. CFRP shell provides rigid support for the liner and acts as a secondary method of
containment should the primary liner fail.
Integral Shaft and Impeller
Large 316 stainless steel core improves impeller
mechanical strength. Integral PFA lined 316 stainless shaft
and impeller optimizes corrosion resistance, strength and
durability of the stainless steel shaft.
