SG & SG-X Series Motor Speed Product Line Ductile Iron External Gear Pumps
SG-04 | SG-05 | SG-07 | SG-10 | SG-14 Models
Viking SG is an extensive series of precision, industrial-duty external gear pumps that develop higher pressures than other Viking pumps, yet offer a similarly broad range of options to handle a diverse range of liquids and applications. With 26 different displacements in five frame sizes to 190 GPM (719 LPM), most applications can be closely matched to a pump operating at motor speeds, without the need for a reducer or gear motor.
The SG-X Series™ UL listed motor speed pump is for fuel oil, providing the best solution for this liquid. It can handle flows up to 11 GPM (42 LPM).
These pumps were designed for greatest reliability, with standard features like spur-type gears (instead of helical gears, which thrust into pump casing and bracket) and rolling element anti-friction bearings (instead of bushings, which wear every time a pump is stopped and the hydrodynamic
film is lost).
Unwanted leaks are prevented by using the best sealing technology available, including single or duplex lip seals, single mechanical component seals, and single or double mechanical cartridge seals with seal plans (SG-10 Series™ & SG-14 Series™ only). Installation is simple, with brackets to close couple to NEMA or IEC motors, or foot mount for speed-reduced applications. Piping is easy, with straight-through, 180° ports with the industry’s broadest variety of threaded ports and flange options.
Viking Pump SG Series Features & Benefits
• Pump design provides superior vacuum capability and volumetric efficiency. Provides application flexibility and reduces life-cycle costs.
• Bi-directional pumping design eliminates cost of second pump, piping, and valving needed for loading/unloading or line stripping. Provides application flexibility and reduces system costs.
• Combination of Hardened 316 stainless steel casing, PEEK vanes and push rods, and carbon construction provides broad chemical compatibility. Enhances application flexibility.
• High efficiency pump with self-priming, short-term dry-run-capabilities that handles entrained gases.Provides non-pulsing, low-shear flow.
• Pressure capabilities to 14 Bar (200 PSI), even on the thinnest liquids. Permits standardizing on single pump for multiple liquids and applications.
• Vane replacement is a 20 minute service item and does not require rotor and shaft removal or detachment of pump from system. Reduces scheduled downtime, and lowers cost of ownership.
• Better design with fewer parts reduces maintenance, and commonality of many parts between frame sizes reduces parts stocking needs. Provides better parts availability and lower the cost of ownership.
• Interchangeable discs may be reversed instead of replaced when worn. Doubles useful life of parts, for reduced life-cycle cost.
• Raised-face flange ports, one-piece casing and bracket, and elastomeric O-ring seals on head, relief valve, and seal gland provides improved sealing reliability. Reduces downtime and cleanup, minimizes chemical exposure.
