Applications Hard-to-Seal Liquids Hazardous & Reactive Liquids Shaft seal leakage is the number one cause of pump downtime and maintenance. Shaft seals wear faster when liquid, air and heat combine at the seal to cause chemical reactions, like: Shaft seals can allow liquids and vapors out, causing hazardous exposure, and can allow air in, causing unwanted chemical reactions. Traditional sealed pumps, including those that require flushing, quenching and barrier fluids, are subject to the same failures as single seals, with the additional cost and maintenance headaches of the associated...

■ Innovative Magnet Design Pump has only two moving parts proven in thousands of tough applications around the world. Simple design minimizes service requirements while providing unmatched durability and reliability. ADVANCED DURABILITY Inner magnet is encapsulated in a laser welded stainless steel canister. One-piece design extends pump life and eliminates maintenance. ■ Unique Rotor Positioning System Thrust washers on both sides of front bushing lock rotor position regardless of application variables. Fixed axial position permits shortterm dry-run and bi-directional operation. ■ Heavy...

Relief valve (not shown) can be adjusted while in service when process conditions change. Provides maximum process up-time. Short-term run dry is possible due to state of the art design and magnet technology. Protects the pump during priming and accidental emptytank situations. Relief Valve Bi-directional pumping design eliminates cost of second pump and piping needed for loading or unloading or line stripping. Provides application flexibility and reduces system costs. ■ Adjustable End Clearance Allows the pump to be adjusted for different viscosities and temperatures if process changes,...
