Some industrial fluids are directly affected by temperature changes. As temperature decreases, the viscosity of the fluid may increase, flow can become more difficult, and the product may even solidify completely. In such applications, simply transferring the fluid is not enough; the product must also be maintained at an appropriate temperature throughout the process. Otherwise, system efficiency may decrease and production disruptions may occur.
Especially for:
- Bitumen
- Chocolate
- Molasses
- Resin
- Adhesives
- Heavy oils
- Certain chemical fluids temperature control is of great importance.
This is where jacketed (heated) pumps come into play.
What Is a Jacketed Pump?
Jacketed pumps are special pumping systems equipped with an additional heating chamber surrounding the pump casing, bearing bracket, or cover.
Hot water, steam, or thermal oil is circulated through this chamber to maintain the fluid inside the pump at a specific temperature.
The purpose is to:
- Maintain fluid flowability
- Facilitate transfer
- Ensure efficient system operation
Why Are They Used?
- To Prevent Fluid Solidification
Some products can harden or become completely solid at low temperatures. For example, bitumen, chocolate, molasses, and paraffin-based products are highly sensitive to heat loss.
Jacketed systems help maintain the fluid at the required temperature throughout the transfer process. However, having only a jacketed pump is not sufficient; the transfer line should also be jacketed to prevent heat loss.
- To Control Viscosity
As temperature decreases, the viscosity of many fluids increases.
High viscosity may lead to:
- Reduced flowability
- Increased pressure
- Higher energy consumption
- Reduced pump performance
Jacketed pumps help keep the fluid within the desired viscosity range.
- To Ensure More Stable and Efficient Transfer
Maintaining the fluid at the proper temperature provides:
- More stable flow rates
- Higher operational efficiency
- More reliable transfer
Temperature control offers significant advantages, especially in processes where production continuity is critical.
Which Industries Use Jacketed Pumps?
Jacketed pump systems are widely used across many industries. Main application areas include:
- Bitumen and asphalt plants
- Food production
- Chocolate and confectionery manufacturing
- Chemical industry
- Paint and resin applications
- Heavy oil transfer systems
Why Is Proper Pump Selection Important?
Every fluid has different:
- Viscosity characteristics
- Operating temperatures
- Transfer conditions
- Process requirements
Therefore, when selecting a jacketed pump, the following factors should be evaluated together:
- Temperature requirements
- Fluid properties
- Flow rate
- Pressure
- System configuration
Selecting the right pump is critical for process efficiency and product quality when handling high-viscosity fluids that require temperature control.
