Product Description
Viking 4193 & 4197 Internal Gear Pumps
The Viking 4193 & 4197 Internal Gear Pumps provide reliable fluid transfer for compressor lubrication, fuels and lube oils. Moreover, their high-speed positive-displacement design supports compact and efficient industrial installations.
Both series deliver flows up to 75 GPM or 17 m³/h. However, they use different construction materials and pressure ratings.
The Viking 4193 uses steel construction for high-pressure lubrication duties. Meanwhile, the Viking 4197 uses stainless steel for greater corrosion resistance.
High-Speed Internal Gear Pumping
The Viking 4193 and 4197 pumps use internal gear technology.
As the rotor and idler gears rotate, spaces form between the gear teeth. These spaces draw liquid into the pump and carry it towards the discharge connection.
The gears then mesh and push the liquid into the system. Consequently, the pump provides smooth and consistent positive-displacement flow.
High-speed operation also allows a compact pump to deliver useful industrial capacities. Therefore, both series suit installations with limited equipment space.

Selecting Between the 4193 and 4197
The correct series depends on the liquid and system requirements.
Choose the Viking 4193 when the application requires:
- Steel pump construction
- Higher pressure up to 17 bar
- Class 300 flanged connections
- Compressor lubrication service
- Compact vertical or motor-mounted arrangements
Choose the Viking 4197 when the application requires:
- Stainless-steel wetted construction
- Greater corrosion resistance
- Wider chemical compatibility
- Non-galling gear materials
- Fluid viscosity up to 5,500 cSt
However, users must confirm compatibility with the exact liquid, concentration and temperature.
Compressor Lubrication Applications
Compressors and other rotating equipment require continuous oil circulation. Therefore, the lubrication pump must provide consistent flow at the required pressure.
The Viking 4193 is particularly suitable for higher-pressure lubrication circuits. Meanwhile, the 4197 provides a corrosion-resistant option for compatible oils and process liquids.
Reliable lubrication can reduce friction, heat and component wear. As a result, it supports longer equipment life and more stable operation.
Fuel and Lube Oil Transfer
Both series can transfer refined fuels and lubricating oils.
Typical liquids include:
- Compressor lubricating oil
- Machinery lube oil
- Refined fuel oils
- Selected jet fuels
- Hydraulic oils
- Circulating oils
- Heat-transfer oils
- Compatible biofuel blends
However, users should confirm material, seal and elastomer compatibility before final selection.
Compact Installation Options
The Viking 4193 supports close-coupled and vertical mounting arrangements. Therefore, it can reduce the required installation footprint.
The Viking 4197 also uses a compact direct-mounted configuration. As a result, it suits packaged systems, lubrication skids and confined plant areas.
Proper pipe support remains important. Moreover, installers should avoid transferring excessive piping loads to the pump casing.
