8124A Series Cast Iron Internal Gear Pumps Information

Product Type
Gear, Positive Displacement, Magnetic Driven, Sealless
Features & Benefits
• Sealless mag drive eliminates the shaft seal to provide the highest level of liquid and vapor containment • All liquid and vapor is hermetically sealed in the pump • Stepped housing keeps the outer magnet from contacting the canister in the unlikely event of bearing failure. • Rotor and Shaft. Optional steel rotors available for operation on viscous liquids. See specifications for details. • Rotatable pump casing in 90° increments, permitting four different port positions. Opposite ports casings also available. • Used especially for hazardous and difficult-to-seal liquids • Extended Pump Life is insured by an in-canister bushing and long spread between shaft bushings, which maximizes shaft support. • Direct drop-in dimensions for the universal seal and onepiece cast bracket provides rigid foundation. • Secure outer magnet support provided by tapered roller bearings. • Multiple port sizes, types and ratings are available including threaded and flanged.
General Description
Viking Pump 8124A Series™ internal gear pump is the perfect solution for petrochemicals, isocyanates, polyols, and more due to the sealless mag drive which keeps hazardous liquids contained. It can handle flows up to 500 GPM (114 m³/h).
