In-Line Design for Cost Savings
Dry Run Capability
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 3298 magdrive pump 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 seal-less 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.
