Industrial pumps

Industrial pumps are machinery designed to transport fluids, sludge or gases through mechanical movements.
Each type of pump has advantages and limitations that depend on the type of fluid to be pumped, the pressure required, and the operating conditions of the system. Proper pump selection is crucial to ensure the efficiency and reliability of the pumping system.

• Positive displacement pumps: For high pressure applications, viscous liquids, and precise dosing.
• Centrifugal pumps: For large flow rates, water, cooling, drainage systems, etc.
• Axial pumps: To move large volumes of water in applications such as irrigation canals, industrial refrigeration and in large drainage systems.
• Screw Pumps: For viscous liquids or in situations where the fluid must not come into contact with air in the pharmaceutical industry, wastewater treatment or in the food industry.
• Vacuum pumps: In systems that require a partial or complete vacuum, such as in laboratories or specific industrial processes.
• Peristaltic pumps: For liquids sensitive to contamination, with high viscosity, or in applications in the chemical, pharmaceutical, food, or biotechnology industries.

Positive displacement pumps

Positive displacement pumps work by trapping a fixed amount of fluid each cycle and forcing it through the pump, regardless of the pressure in the system.

• Piston (or plunger) pumps: In these pumps the fluid is displaced by the reciprocating movement of a piston within a cylinder. They are used in high pressure systems or where a constant and controlled flow is required such as in cleaning applications or hydraulic systems.
• Diaphragm pumps: Use a flexible membrane that moves back and forth to create suction and expel fluid. They are used in applications where viscous or corrosive liquids are handled, such as in the chemical industry or water treatment.
• Gear pumps: In these pumps two gears rotate relative to each other, trapping the fluid and pushing it outward. They are used in oil and fuel pumps, and in lubrication processes in engines and industrial machinery.
• Peristaltic pumps: The fluid moves through a flexible tube that is compressed by a roller that advances along the tube. They are used in chemical, pharmaceutical, food and biotechnology applications, and in handling viscous or delicate fluids.
• Lobe pumps: Use two lobes (usually oval in shape) that rotate to create fluid flow. They are used in pumps for viscous liquids, sludge, and in food transfer processes such as juices or food pastes.

Centrifugal pumps

Centrifugal pumps are the most common and are based on the conversion of the mechanical energy of the motor into kinetic energy, which is then converted into pressure energy to move the fluid.

• Single-stage pumps: They have a single impeller that increases the velocity of the fluid, and kinetic energy is converted to pressure when the fluid decelerates. Used in water circulation systems, cooling systems, and in the supply of water in domestic and industrial systems.
• Multistage pumps: Use multiple impellers in series to increase fluid pressure. They are used in systems that require high pressure performance, such as heating systems, large-scale drinking water, and in oil and gas industry applications.
• Submersible pumps: They are designed to operate underwater or in liquids, with the motor submerged in the fluid to be pumped. Used in wells, flood drains, and pumping systems in underground tunnels, deep wells or in sewage systems.
• Turbine pumps: Use a series of turbines to propel the fluid. They are used in large-scale water pumping applications, such as irrigation systems, in power plants and in water treatment plants.

Axial pumps

Axial pumps use an impeller with a design that allows fluid to move along the axis of the pump, unlike centrifugal pumps that push it at a radial angle. Fluid enters and exits in the same direction, allowing high volume flow at low pressures. They are mainly used to move large volumes of water in applications such as irrigation canals, industrial refrigeration and in large drainage systems.

Screw pumps

Screw pumps operate by using a helical screw that moves fluid along the pump shaft without the need for valves or rotating impellers. They are especially useful for viscous liquids or in situations where the fluid must not come into contact with air. They are used in the pharmaceutical industry, wastewater treatment or in the food industry to handle sludge or food products such as pasta.

Vacuum pumps

Vacuum pumps are those designed to remove air and other gases from a closed space, creating a partial or complete vacuum.

• Piston pumps: They use a piston to generate vacuum by suction and compression of air. They are used in laboratories, packaging processes and semiconductor manufacturing.
• Diaphragm pumps: Use a flexible diaphragm that moves to create suction and evacuation of air. They are used in low pressure gas or liquid evacuation systems.
• Rotary blade pumps: They use a set of blades that rotate to generate vacuum by expelling air. They are used in industrial high vacuum systems, in refrigeration equipment or in chemical processes.

Peristaltic pumps

Peristaltic pumps use a system of flexible tubes and a roller that compresses the tubes, moving the fluid in one direction. They are ideal for viscous fluids, sensitive to contamination or where precise flow control is required such as in the pharmaceutical, food, and biotechnology industries.

Fluid Compressors

Fluid compressors are machines designed to increase the pressure of a gas or vapor, reducing its volume. They are used in a variety of industrial applications, such as air conditioning systems, refrigeration, power systems, chemical processing plants, and many more. Compressors are essential to handle gases efficiently, generating high pressure for various applications.

There are several types of compressors depending on their operation and the type of gas they process. The choice of a type of compressor depends on the application, the pressure and flow required, as well as the characteristics of the gas or fluid to be compressed.

• Positive displacement compressors: Capture a quantity of gas and compress it to a smaller volume. They are ideal for high pressure or relatively low flow applications.
• Dynamic compressors: They use a continuous flow of gas and accelerate it to increase its pressure. They are best suited for high flow rates and moderate pressures.
• Hybrid/Dual-Stage Compressors: Combine features of positive displacement and dynamic compressors for greater efficiency and flexibility.
• High and low temperature/cryogenic compressors: Specially designed to handle gases at extremely high or low temperatures.
• Natural Gas Compressors: Specifically designed to compress natural gas and other gas mixtures at high pressure for transport through pipelines.

Positive displacement compressors

Positive displacement compressors work by capturing a fixed amount of gas each cycle and then compressing it into a smaller volume, increasing its pressure.

• Piston (or reciprocating) compressors: They have a piston that moves back and forth inside a cylinder, sucking and compressing gas. This is one of the most common and versatile compressors. They are suitable for high pressure and relatively low flow applications. They are used in refrigeration systems, air compression, and power systems in workshops or HVAC equipment.
• Screw (or rotary displacement) compressors: These use two helical rotors (screws) that rotate and will trap the gas between them, compressing it as the gas moves toward the end of the screws. They are more efficient for higher gas flow rates and work well in continuous industrial applications. They are common in the construction industry, food processing, industrial systems, and refrigeration applications.
• Lobe compressors: Use two rotating lobes that rotate in opposite directions to compress the gas trapped between them. The gas moves as the lobes rotate and is compressed in the process. They are commonly used in low pressure applications and for light or non-corrosive gases. They are used in chemical processes, in natural gas compression and in ventilation systems.
• Rotary blade compressors: They consist of a rotor that rotates inside a casing. The gas is captured by the rotating blades and compressed as they move out of the casing. They are suitable for applications that require a constant flow and are used in refrigeration and compressed air systems or in power plants.

Dynamic compressors

Dynamic compressors do not operate by positive displacement, but rather transfer energy to the gas continuously to increase its speed and pressure.

• Centrifugal compressors: They use an impeller that accelerates the gas using centrifugal force. As the gas moves outward, its pressure is increased thanks to a series of stages (impellers) in the compressor. They are suitable for high flow rates and moderate pressures, such as in power generation plants, gas pumping stations, and industrial refrigeration systems.
• Axial compressors: The gas flows in a direction parallel to the axis of the compressor, and is compressed in stages by a series of fixed and moving blades. Used for applications that require high flow rates and relatively low pressures, such as in aviation (in aircraft engines) and in large industrial facilities.

Hybrid/Dual Stage Compressors

Hybrid compressors combine two stages of compression, one positive displacement and one dynamic, to increase pressure in two phases and make the process more efficient, reducing temperature and effort. They are used in high pressure applications or where the fluid has characteristics that are difficult to handle in a single compression stage.

High and low temperature/cryogenic compressors

Some compressors are designed to handle gases at extremely high or low temperatures. Cryogenic compressors specifically are specially designed to work with cryogenic gases at extremely low temperatures (below -150°C). These compressors can be positive displacement or dynamic, depending on the application. They are used in the cryogenic refrigeration industry, such as in the transportation of liquefied natural gas (LNG) or in the production of oxygen and nitrogen at low temperatures.

Natural Gas Compressors

These compressors are specifically designed to compress natural gas and other gas mixtures at high pressure for transport through pipelines. Natural gas compressors are often piston or screw compressors, which operate at high pressures to ensure that the gas is transported efficiently and safely. They are used in natural gas compression stations, on drilling platforms, and in gas processing plants.
