About Viking 495 Series & 4195 Series Internal Gear Pumps
The Viking 495 Series and 4195 Series are high-speed internal gear pumps developed for thin to moderate viscosity liquid handling in space-restricted installations. Both series operate at motor speed to provide economical pumping solutions for refined fuels, lube oils, lubrication systems, and other industrial fluid transfer applications.
The 495 Series is tailored for applications requiring flows up to 115 GPM (26 m3/h), while the 4195 Series extends capacity up to 580 GPM (132 m3/h) for larger flow requirements.
Features include:
- Compact internal gear pump design for tight space constraints.
- High-speed operation for economical performance in thin to moderate viscosity services.
- Vertical mounting options are available on select configurations to further reduce footprint.
- Multiple porting, drive, and mounting configurations to suit system requirements.
- Designed for thin to moderate viscosity liquids across a range of operating conditions.
Typical applications include:
- Refined Fuels (e.g., gasoline, diesel)
- Lube Oils and Machinery Lubrication
- Rotating Equipment Lubrication
- General industrial fluid transfer and circulation
