About Viking SG Series Spur Gear Pumps
The Viking SG Series spur gear pump is a versatile external gear pump designed for high-pressure performance and reliability in demanding industrial applications like pipeline injection, sampling, and oil polishing.
The SG Series accommodates a broad range of liquids and operating conditions, offering durable performance across many flow rates and pressures. It can handle flows up to 190 GPM (719 LPM) with viscosity capabilities from 28 to 1,000,000 SSU (1 to 250,000 cSt) and temperature ranges from -40 °F to +450 °F.
Features include:
- Flexible mounting options include close-coupled or foot-mounted configurations
- High-pressure capability is provided by needle roller bearings, with optional sleeve bearings
- Dual-pump configurations deliver two flow rates from a single drive, reducing system cost and complexity
Typical applications include:
- Pipeline injection
- Pipeline sampling
- Oil polishing
- Refined fuels
- Lube oils
- Rotating equipment lubrication
- Chemical transfer
- Mobile pump carts
