There are many pumps in the market which can be confusing when looking for a pump. Your pump selection is mainly based on the application, including the type of fluid you want to pump, the distance you want to move the liquid, and the volume you need to move within a specific time frame. It is essential to understand the different types of pumps to make things easier for you when selecting a pump.
There are two main categories of pumps:
- Dynamic pumps comprising centrifugal, vertical and horizontal centrifugal, submersible and fire hydrant.
- Positive displacement pumps including diaphragm, gear, peristatic, lobe, and piston.
Here is a deeper look into them.
These are the most commonly used worldwide because their working mechanism is easy, efficient, and proven. The pump is strong, and the fluid pressure increases from the pump’s inlet to the outlet whenever it is in action. Then the change of pressure propels the liquid through the system. It enhances the force by transmitting the mechanical power from the electric motor to the fluid via a revolving impeller. Therefore, the liquid enters the center of the impeller and exits through the blades.
Depending on the application, submersible pumps are also called septic, sewage, and stormwater pumps. PumpBiz submersible pumps are used in industrial, commercial, domestic, building services, and rainwater recycling applications. They come in handy for shifting subsoil water, blackwater, stormwater, greywater, chemicals, bore water, trade waste, and foodstuffs. These pumps feature different impellers, including multi-stage, vortex, closed, contra block, cutter, and single channel. There is also a wide range of selection for various applications.
Fire hydrant systems
These are also known as fire pumps used to enhance the capacity of fire fighting of construction by boosting the pressure within the hydrant system because the mains is not enough. It is used in applications like irrigation and water transfer.
Diaphragm pumps are mainly used in continuous operations like industrial, mining, and general plants. They also come in handy for transmitting food manufacturing, chemical, and underground coal mines. Generally, these pumps are used in applications where power is not obtainable, especially in unstable and explosive areas. They feature two diaphragms operated with condensed air.
Also known as tube pumps, these kinds of positive displacement pumps are used in water treatment industries, food processing, and chemicals. The pump provides a stable flow for measuring materials such as toothpaste and other kinds of chemicals.
These pumps are designed with a revolving positive dislocation mechanism that enables them to move a stable amount of fluid with every rotation. They can pump at high forces and exceed pumping high thickness fluid efficiently. However, a gear pump doesn’t have valves, making it suitable for handling thick liquids like grease oils.
Lobe pumps have various features, including corrosion resistance, high efficiency, reliability, and hygienic qualities, and can handle fluids with high thickness without harming them. They are made with stainless steel and have superior pumping rooms to move slurries.
Understand the properties of the fluids you intend to pump to help you select an ideal pump.
