Positive Displacement Pumps

A positive displacement pump is a type of pump used to move fluids such as liquid or gas from one place to another. Positive displacement pump enables fluid to be transported by a moving part, such as a piston, rotor or diaphragm, enlarging and contracting a cavity within the pump.

The positive displacement pump is widely used in the transport of liquids and gases at high pressures and high volumes. In addition, this type of pump can also be used for conveying low viscosity liquids, high viscosity liquids and solids.

Among the various types of positive displacement pumps there are different types such as gear, reciprocating, rotary, diaphragm and screw pumps. Each pump type is designed for different applications.

The gear pump narrows the gap between the two gears, allowing the fluid to be transported. The reciprocating pump provides the transport of fluid by the back and forth movement of a piston in the pump. A rotary pump allows fluid to be transported by narrowing the space inside a rotor. The diaphragm pump provides the transport of fluid by the action of a diaphragm. The screw pump ensures that the fluid is transported by the rotation of the screws.

Each type of positive displacement pump has its advantages and disadvantages and should be chosen depending on the application.

Positive Displacement Pump Usage Areas

The positive displacement pump is a common type of pump used for many industrial applications. This type of pump can handle many different fluids and can be used in different industrial sectors.

Here are some application areas where positive displacement pumps are commonly used:

1. Chemical industry: Positive displacement pump is used to transport chemical products. For example, acids, alcohols, solvents and other chemical liquids.
2. Food industry: Positive displacement pump is used in food processing and packaging applications, for example to transport sugar, milk, oil, juice and other food liquids.
3. Petroleum industry: Positive displacement pump is used to transport oil, natural gas and petroleum products. For example, mud, crude oil, bitumen, petroleum products, etc.
4. Water treatment industry: In water treatment and wastewater treatment plants, for example, a positive displacement pump is used to transport sludge, chemicals and other fluids.
5. Pharmaceutical industry: In pharmaceutical manufacturing and packaging processes, for example, positive displacement pump is used to transport sirups, tablets, creams and other pharmaceutical liquids.
6. Marine industry: In the marine industry, for example, a positive displacement pump is used to transport fuel, oil, water and other fluids.

Because the positive displacement pump can be used in many different application areas, there are many cross-industry applications.
