INTERNAL GEAR INDUSTRY’S FIRST FULLY API 676 COMPLIANT INTERNAL GEAR PUMP Higher pressures with factory approval With special construction With special construction

INTERNAL GEAR Internal Gear (or gear-within-a-gear) technology was invented in 1902 by the founder of Viking Pump, which is the world-leading provider of internal gear process pumps. Internal gear pumps are rotary positive displacement pumps which move the same amount of fluid with each revolution of the shaft. The flow rate is directly proportional to the speed, which enables easy control over the entire performance range using variable speed drives.

REDUCES RISK INTERNAL GEAR Why Use XPD 676 for Critical Chemical, Petrochemical, Oil & Gas Process Applications? Reduced Risk of Leakage • Static O-ring sealed joints provides improved sealing vs. flat gaskets • Designed to operate continuously for 25,000 hours without need for replacement • Metal around tapped holes at least half the bolt diameter • Enlarged seal chamber provides greater liquid volume for enhanced cooling • Non-Destructive Evaluation of castings and welds ensures quality • Four-bolt mount with O-ring face seal helps prevent leakage & emissions • Performance tests validate integrity...

DOES YOUR API 676 PUMP COMPLY WITH ALL OF THESE? If not, it doesn’t comply with API 676 standards. Materials  of Construction – pressure-containing components carbon steel (ASTM A216, Grade WCC). Bearing  Life – minimum 25,000 hour L-10 life at maximum speed and pressure conditions. Seal  Gland – accepts most major brands of API 682 cartridge seals to enable compliance with plant seal standards. Casing  Drain and Seal Chamber Venting Port – enable complete draining of casing before opening pump for maintenance. Fasteners  have the material grade and manufacturer’s identification symbols...
