DOES YOUR API 676 PUMPCOMPLY WITH ALL OF THESE?
If not, it doesn’t comply with API 676 standards. Viking XPD DOES: • Bearing Lubrication – grease lubricated with overfill protection standard, with lip seals or optional labyrinth seals to protect bearings from external contamination.
• O-Ring Static Seals on Bracket/Casing and Casing/Head Interfaces – provides better sealing at high pressures than flat gaskets.
• Jacketed Bracket and Casing – enables heating or cooling. Jackets are designed for minimum of 5.2 barg (75 psig) working pressure and are suitable for hydrostatic testing at a minimum of 8 barg (115 psig). Jacketed head optional.

• Materials of Construction – pressure-containing components are carbon steel (ASTM A216, Grade WCB).
• Bearing Life – tapered roller type thrust bearings are designed for minimum 25,000 hour L-10 life at maximum speed and pressure conditions.
• Bearings Mounting – bearings are located on the shaft using collars, because snap rings and spring-type washers are not acceptable.
• 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 applied.
• In pressure containing areas, metal equal in thickness to at least half the nominal bolt diameter (including the allowance for corrosion) has been left around and below the bottom of drilled and threaded holes. The depth of threaded holes is at least 1.5 times the stud diameter.
• All threaded openings not connected to piping are plugged with long-shank, hex-head, taper-threaded plugs in accordance with ASME B16.11.
• Flanges conform to ISO 7005-1 PN 50 and ASME B16.5 Class 300.
• Mounting surfaces (feet) are machined to 25 µm (0.001 in.) flatness, with a minimum finish of 6.3 µm (250 µin.) Ra, and on models with both casing and bracket feet, they are flat and parallel within 150 µm/m (0.002 in./ft) of distance between them. In addition, upper side of mounting feet are spot faced parallel to the mounting surface for superior alignment.
• The casing, head and bracket are designed with an additional 3 mm (0.12 in.) corrosion allowance over and above the casing thickness needed for the maximum allowable casing pressure (MACP).
• Nameplate – includes all relevant information including purchaser’s item number, serial number, and pump size and type, minimum and maximum allowable design limits and rating data (including pressures, temperatures, speeds, and power), MAWPs and temperatures, hydrostatic test pressures and critical speeds.
• Metal Port Covers – protects pump internals prior to installation.
• Tight shaft tolerances to provide close fit with the coupling, reduced tendency to work loose and lower vibration: +0.0000 / -.0005 on H-LS sizes; +.0000/ -.0010 on Q-RS sizes.
• Rectangular keyways which transmit more torque because the keyseat is stronger.
• Keyway fillet radii conforming to ASME B17.1 to reduce stress concentration.
• Tapered shaft hub on R and larger sizes to reduce the clearances between the shaft and the coupling bore.
