When choosing a pump for your industrial or commercial applications, there are several factors that you need to consider. The role of temperature is a major one, how hot or cold the fluid in the system is, the levels of heat generated by the pump and other equipment, and the particular range required for the operation, being key. So why is the role of temperature so integral to the pump selection process? In this blog, we will outline the ways in which temperature can have an effect on your pump and operations. These are as follows:
Corrosion to construction parts
The temperature of the pump can cause corrosion to the parts or construction materials if you plan to be pumping specific kinds of chemicals. Keep in mind that the hotter the liquid, the more corrosive effect it can have. Thus, it is crucial to check the compatibility of different chemicals and the temperature at which you are going to be pumping.
The pump’s components
With an increase in the temperature, heat gets transferred from gland packing to the bearing through the shaft. This takes a toll on the bearing by shortening its life and possibly even seizing it if the pump’s gland is saturated. This must be avoided at all costs for the pump to be function at peak efficiency.
Viscosity of liquids
Fluids that are affected by temperature can see a change in viscosity during the pumping process. For instance, some become runny when heated, thus influencing how they will be pumped. This is why it is important to understand how temperature can change the viscosity of your product in order to select the right pump.
Expansion of parts
Metal parts can expand at varying rates at high temperatures. So it is essential to finalize the materials of construction while you are choosing the pump itself.
Maintaining the temperature
In certain cases, you may need to maintain a specific temperature or a range of temperatures depending on the application. You can achieve this by preserving the conditions of the flow or use a heating jacket which permits you to maintain higher temperatures. Conversely, you can implement proper insulation in the system to maintain a lower temperature.
Even if you have a suction for the pump that is flooded, it is important to note that you will still have to take the vapour pressure of the liquid, as well as the temperature into consideration in order to ensure that your pump contains the right Net Positive Suction Head Available (NPSHa).For more information on industrial pumps, motors, and other equipment, feel free to reach VEMC on +91-9819907445.
