What Is a Pump Plunger?
Pump plungers are a type of pump used to supply and transfer liquids and gases.
It is designed to move liquid or gas by utilizing the volume change occurring when a cylindrical piston (plunger) moves in a linear reciprocating motion inside a compartment in the pump housing.
Operating principle and structure
- Precise adjustment of discharge volume is possible
- High suction and discharge pressures can be set
Therefore, pump plungers are used in equipment requiring high metering performance and discharge pressure.
Uses of Pump Plungers
Because of its ability to accurately adjust the discharge volume, the pump plunger is used in the following locations where high quantitative performance is required.
- Chemical laboratory equipment
- Medical drug injectors used for insulin pump therapy, etc.
- Fuel supply for automobiles
- Mixing liquids in pharmaceutical production lines
- Injection of materials in food production lines
- Chlorine injection in water supply facilities
- Equipment for water quality control in water storage tanks
The ability to achieve high discharge pressure is also used in high-pressure household cleaners and high-pressure gas appliances.
Principle of Pump Plungers
The basic principle of operation is the same for all pumps. To repeat this process, the volume of the compartment in the housing is changed to apply pressure to the liquid or gas inside to provide sufficient energy for transfer. A pump with this principle of operation is called a positive displacement pump.
There are two main types of positive displacement pumps, reciprocating pumps, and rotary pumps, depending on the difference in the internal mechanism that induces the volume change.
Reciprocating pumps use the same principle of a syringe to suck in and discharge liquid or gas by moving a moving part in a straight line back and forth.
When an impeller or rotor rotates, a rotary pump moves a certain amount of liquid or gas.
Because of their principle of operation and the characteristics of their structure, positive displacement pumps are also called metering pumps. They can suction and discharge a fixed amount of liquid or gas with a high degree of accuracy.
Pump plungers are a type of reciprocating pump, and as the name implies, the linear reciprocating motion of the plunger achieves the volume change inside the compartment.
