Industrial pumps

Industrial pumps are an essential component of many industries, providing a reliable and efficient means of transferring liquids and gases from one area to another. They are designed to meet the specific needs of each application, from handling corrosive liquids and aggressive fluids to pressurizing and transferring both liquids and gases. Industrial pumps are used in areas and industries such as power generation, oil and gas, water and wastewater treatment, mining, chemical processing and food and beverage production. Industrial pumps can be divided into two main types: positive displacement pumps and centrifugal pumps. Each type of pump has its own advantages and disadvantages, making it important to select the appropriate type for the specific needs of the application.

Positive displacement pumps 

Positive displacement pumps are a type of mechanical pump that utilize the principle of enlarging (priming) and reducing (squeezing) the space in the pump housing to generate a constant volume displacement. This displacement is (approximately) directly proportional to the speed of the pump, meaning that the delivery (flow rate) of the pump is independent of the delivery pressure. In positive displacement pumps, a predetermined amount of fluid is moved with each cycle. The maximum head pressure is primarily limited by the mechanical strength of the pump. 

Centrifugal pumps 

Centrifugal pumps are the collective name for pumps that use centrifugal force to transfer liquids from one location to another by creating a vacuum. In its simplest form, a centrifugal pump typically consists of a rotating impeller with blades, housed in a pump casing. The suction line is connected to the central inlet of the pump casing, and the pressure line is connected to the outer circumference. When the impeller rotates, the centrifugal force causes the liquid to be propelled from the center to the outer periphery. 

INDUSTRIAL Pump types and their applications  

  • Sanitary pumps are designed for use in applications where hygiene and cleanliness are critical, such as the food, beverage, pharmaceutical, and biotech industries.
  • Hygienic rotary piston pumps can, among other things, pump cold and viscous substances, such as butter, with few dead spaces for easy cleaning.  
  • Rotary lobe pumps with food certificates are ideal for pumping yogurt with large delivery chambers, preventing damage to delicate ingredients like strawberries.  
  • Self-priming peristaltic pumps are often used in breweries to pump mash and meter diatomaceous earth in filtration processes.  
  • Self-priming air-operated diaphragm pumps are designed to pump water containing sand and other dirt particles without relying on an external power source.  
  • Eccentric screw pumps are used in water treatment, chemical, and food industry processes to convey abrasive liquids with high solids content.  
  • Metering pumps can inject chemicals into the process under high pressure, making them ideal for use in refineries and large chemical plants.  
  • Heavy-duty gear pumps are designed to handle media with high viscosity and temperature, making them ideal for pumping tar and asphalt.
