External Gear Pump
Description
While external gear pumps are similar to internal gear pumps, the only difference is the use of two identical gears rotating against each other — one gear is driven by a motor and it in turn drives the other gear.External gear pumps are mostly used where high pressure is required e.g hydraulic applications.
Benefits of the internal gear pump:
• High pressure
• Relatively high speed
• Silent operation
• Suitable for wide variety of materials
• Flexible design
Features of VIKING External Gear Pump:
• Flow up to 45 m3/hr
• Pressure up to 170 bar
• Viscosity up to 250,000 cst
• Temp from -40 C to +230 C
• Various Sealing options
• Anti-friction needle bearings with high load carrying capacity
• Hardened steel gears and shafts to extend pressure capability and minimize wear
• High speed design eliminates need for reducer
• Easy to install in tight spaces due to compact close- coupled design
• Available with seal-less mag-drive options
APPLICATIONS:
• Fuel oils and lube oils
• Chemical additives
• Mixing and blending (double pump)
• Industrial hydraulic applications (log splitters, lifts, etc.)
• Acids and caustic (stainless steel or composite construction)
• Low volume transfer or application
