Product Description
Viking 4224A Jacketed Bitumen Pump
The Viking 4224A Jacketed Bitumen Pump provides dependable transfer of heavy and temperature-sensitive liquids. Moreover, its positive-displacement internal gear design supports steady flow across demanding industrial processes.
Integral jacket chambers surround the pump internals and seal area. Therefore, operators can circulate steam or hot oil before startup to heat the pump efficiently.
This heating capability helps maintain the required fluid viscosity. As a result, the pump can handle bitumen, asphalt emulsions, coal tar, heavy fuel oil, waxes and rubber solutions more effectively.
Heated Pumping for Viscous Liquids
Bitumen and similar liquids become difficult to pump when their temperature falls. Consequently, the pump and piping system must maintain a suitable operating temperature.
The Viking 4224A transfers heat directly to critical pump components through its jacketed bracket and head. Therefore, it can reduce startup difficulties caused by hardened or highly viscous material.
Operators can use either steam or hot oil as the heating medium. However, they must select the heating pressure and temperature according to the pump configuration and process requirements.
Key Benefits of the Viking 4224A
The Viking 4224A internal gear pump offers several practical advantages:
- Cast-iron construction for demanding industrial service
- Integral steam or hot-oil jacket chambers
- Positive-displacement internal gear technology
- Flow capacity up to 420 GPM
- Metric flow capacity up to 95 m³/h
- Maximum pressure up to 14 bar
- Viscosity handling up to 440,000 cSt
- Fluid temperatures up to 230°C
- Strong priming characteristics
- Smooth and consistent fluid transfer
- Mechanical and triple-lip seal options
- Flanged, NPT and BSP port options
- Rotatable 90-degree casing options
- Multiple gear-reducer and V-belt drive arrangements

Together, these features support reliable transfer, circulation and metering of heavy industrial liquids.
Flow and Operating Performance
The current Viking 4224A Series specification includes:
- Maximum flow: 420 GPM
- Maximum metric flow: 95 m³/h
- Maximum pressure: 200 PSI
- Maximum metric pressure: 14 bar
- Viscosity range: 1 to 440,000 cSt
- Temperature range: -51°C to 230°C
- Maximum listed speed: 420 rpm
- Standard listed port size: 4 inches
However, actual performance depends on the selected model, operating speed and liquid properties. Therefore, users should confirm the complete duty point before ordering.
Internal Gear Pump Operation
The Viking 4224A uses an internal gear and idler gear to move the liquid.
As the gears rotate, spaces form between their teeth. These spaces draw the liquid into the pump and carry it towards the discharge side.
The gears then mesh again and push the liquid into the discharge piping. Consequently, the pump delivers a consistent positive-displacement flow.
This operating principle suits viscous products because the pump does not depend on high liquid velocity. Moreover, reduced operating speed can support gentle handling of shear-sensitive asphalt emulsions.
Jacketed Temperature Control
The pump includes jacket chambers around important internal areas.
Steam Heating
Steam can heat the pump before startup. Therefore, it helps soften solidified or highly viscous product inside the casing.
Hot-Oil Heating
Hot oil provides another controlled heating option. In addition, it may suit facilities that already use a thermal-oil circulation system.
The heating system should bring the product to a pumpable condition before the drive starts. Consequently, operators can reduce overload, component wear and startup delays.
Seal and Port Options
Available sealing arrangements include:
- Component mechanical seals
- Cartridge mechanical seals
- Cartridge triple-lip seals
Available port arrangements include:
- NPT connections
- BSP connections
- ASME or ANSI flanges
- Rotatable right-angle ports
Therefore, users can configure the pump for different piping layouts and leakage-control requirements.
However, the correct seal depends on the liquid temperature, viscosity and chemical properties.
