4. Types
Process pumps come in various types, each designed for specific applications and fluid characteristics. Understanding their working mechanisms helps selecting the right pump for specific applications and ensures their efficient operation. The three main categories are centrifugal, positive displacement, and specialty.
4.1 Centrifugal
Centrifugal pumps operate by converting rotational kinetic energy, typically from an electric motor or engine, into hydrodynamic energy of fluid flow. The impeller, a rotating disk with vanes, accelerates the fluid outward from the center of rotation. As the fluid leaves the impeller, it slows down, and its kinetic energy is converted into pressure. Many industrial processes use this type of process pumps because it is simple, efficient, and can handle large volumes of fluid.
Common applications
- Water supply and distribution: in municipal and industrial water systems.
- Chemical processing: for moving corrosive and non-corrosive fluids.
- HVAC (Heating, Ventilation and Air Conditioning) systems: circulating water in heating and cooling systems.
4.2 Positive displacement
Positive displacement pumps work by trapping a fixed volume of fluid and moving it through the pump housing. They are ideal for applications requiring precise flow control and handling viscous or shear-sensitive fluids. The movement can be achieved through various mechanisms:
- Diaphragm pumps: use a flexible diaphragm and check valves to move fluids; suitable for corrosive or abrasive fluids.
- Gear pumps: use two rotating gears to move fluid through the pump, ideal for high-viscosity fluids like oils and polymers.
- Piston Pumps: A piston moves back and forth in a cylinder, drawing fluid in on the intake stroke and pushing it out on the discharge stroke. Suitable for high-pressure applications.
Common applications
- Chemical industry: handling aggressive chemicals and slurries.
- Water and Wastewater Treatment: dosing chemicals and transferring sludge.
- Paints and Coatings: transferring, mixing and spraying of fluids.
4.2.1 Pneumatic pumps
They are a specific type that uses compressed air to move fluids. Unlike electrical or hydraulic pumps, pneumatic pumps utilize air pressure to create movement. This is why they are ideal for certain applications where electrical connections are not available or when the process is within a hazardous explosive location.
4.2.2 How do they work?
Basically, they work using compressed air to create a pressure difference. This pressure difference moves the fluid through the equipment. Here’s a basic outline of how they work:
- Air compression: Compressed air is supplied, usually from an external compressor that supplies the entire factory.
- Pressure transfer: The compressed air enters a chamber and creates a pressure difference between the air and fluid sections of the pump.
- Fluid movement: The pressure forces the fluid through the device and out the discharge side.
4.3 Specialty
Specialty ones handle specific applications that standard ones cannot manage. They come with unique features tailored to meet the demands of particular industries and processes, whether dealing with highly viscous fluids, delicate substances, or hazardous materials. Some types are peristaltic, screw, or magnetic drive pumps:
- Peristaltic: use a rotating roller to compress a flexible tube, ideal for handling delicate or shear-sensitive fluids.
- Screw: use one or multiple screws to move fluid, suitable for high-viscosity and high-pressure applications.
- Magnetic drive: use a magnetic coupling to eliminate the need for shaft seals, ideal for hazardous or corrosive fluids.
Common applications
- Chemical processing: magnetic drive ones are preferred for leak-free operation and handling of aggressive chemicals.
- Oil and gas: screw ones are common for their ability to handle multiphase fluids.
- Medical devices and food processing: peristaltic pumps are used for their gentle pumping action and precision dosing capabilities.
5. Applications of industrial process pumps
