When selecting the right pump for food, beverage and other sensitive applications, it is important to consider the requirements of the application, the properties of the fluids being transferred and the overall cost-effectiveness of the pump technology. While there are many different types of pumps available, each with their own unique set of advantages and disadvantages, there are three main types of pumps that are widely used in these types of applications: centrifugal pumps, rotary lobe pumps and diaphragm pumps.
Centrifugal pumps are a popular choice for transferring high-volume fluids at a reasonable price point. These pumps are highly efficient, requiring minimal maintenance and producing minimal heat, making them ideal for applications where heat transfer may be a concern. Additionally, centrifugal pumps are highly versatile, able to handle a wide range of fluids, including those with low viscosity.
Rotary lobe pumps, also commonly referred to as positive displacement (PD) pumps, are another popular choice for sensitive applications. These pumps are able to transfer fluids at high flow rates and high pressures, making them ideal for higher viscosity fluids. Additionally, rotary lobe pumps are highly efficient, producing minimal shear and preserving the integrity of the fluids being transferred.
Diaphragm pumps are an ideal choice for handling slurries and solids, making them ideal for initial ingredient transfer and difficult ingredients. These pumps are highly efficient and reliable, able to handle a wide variety of fluids while producing minimal heat and shear. Additionally, diaphragm pumps are highly sanitary, making them an excellent choice for food and beverage applications.
When selecting the right pump for your food, beverage and other sensitive applications, it is important to consider the specific requirements of your application, including the properties of the fluids being transferred, the volume of fluids required and the cost-effectiveness of the pump technology. By taking these factors into account, you can select the right pump for your unique application and ensure the safe, reliable and efficient transfer of fluids in even the most sensitive applications.
