What Is a Pressure Pump?
Pressure pumps are utilized to draw in liquids or gases and transfer them to the desired location. Due to their capacity to forcefully transfer liquids and gases, these pumps are employed when there is no difference in elevation, when pumping from low to high, or when high-speed transfer is required.
All pumps operate based on the pressure difference between the suction and discharge ports, and from this perspective, all pumps can be categorized as “pressure pumps.” However, it is commonly used as a general term for pumps employed in toilet drainage, sewage systems, pile erection work, and tunneling sites.
Uses of Pressure Pumps
Pumps used for the following applications are generally referred to as pressure pumps:
- Household toilet drainage systems
- Transfer of water and sewage between water supply and drainage tanks in high-rise buildings
- Discharge of excavated soil containing toxic gases at excavation sites
- Pumping muddy water during pile erection work
- Driving filtration equipment at sewage treatment facilities
- Lifting sand during dredging work
- Special type fuel injection equipment
- Submersible throw-in pumps
- Material transfer systems in food processing plants
- Oil supply systems
- Water supply systems using wells
Principle of Pressure Pumps
The fundamental operating principle of pumps is generally consistent: liquids and gases are moved by alternately suctioning and discharging a pump using various mechanisms to create a pressure differential within the pump. From this perspective, all pumps can be categorized as pressure pumps.
Based on their structural characteristics, pumps can be categorized into two primary types: those that rotate a turbine inside the pump at high speed and those that alter the pressure within a compartment located inside the pump.
The first type is referred to as a non-volumetric pump and can pump a relatively large volume of liquid at low pressure. However, depending on the nature of the liquid, accurately setting flow velocity and other parameters may be challenging.
The second type of pump is known as a positive displacement pump, which can maintain high suction and discharge pressures and precisely set flow rates but does not handle large volumes of liquid.
Today, the term “pressure pump” is commonly used as a general term for pumps employed in various systems and work processes, rather than denoting a specific type of pump.
