8123A Series Steel Externals 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 • Used especially for hazardous and difficult-to-seal liquids • The inner magnet is the driven magnet, aligned by magnetic force passing through the canister; the inner magnet assembly is shielded in a laser welded 316SS housing to prevent exposure of the magnets to the liquid • Stepped housing keeps the outer magnet from contacting the canister in the unlikely event of bearing failure • Multiple port sizes, types and ratings are available including threaded and flanged • Adjustable Internal relief valve standard, optional return-to-tank and jacketed available • The outer magnet is the drive magnet, driven directly by the motor • Rotatable pump casing in 90° increments, permitting four different port positions. Opposite ports casings also available • One-piece cast bracket provides rigid foundation that is dimensionally interchangeable with Universal Product Line pumps
General Description
Viking Pump 8123A Series™ internal gear pump is the ideal 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).
