Positive displacement pumps have been around for centuries, providing reliable, efficient solutions for industrial, agricultural, and domestic applications. They are used to transfer a wide variety of liquids, including water, oils, fuels, chemicals, and more. In this blog, we'll explore the benefits of positive displacement pumps, discuss what they are and how they work, and examine some common applications. With the right information, you can make an informed decision on whether a positive displacement pump is the best fit for your needs.
Positive displacement pumps are so named because they create a positive displacement within the pump's chamber. This displacement is created by the pump's rotating impeller, which forces the liquid to flow through the pump's inlet and out the outlet. The impeller is attached to a rotating shaft, which is powered by an electric motor or a diesel engine.

There are many different types of positive displacement pumps, but most of them rely on one of two mechanisms to create the displacement: reciprocating or rotating.
Reciprocating pumps are the simplest type of positive displacement pump. They use a piston to create the displacement by moving up and down in the pump's chamber. This motion causes the liquid to be drawn in and expelled from the pump.
Rotating pumps use a rotating impeller to create the displacement. The impeller is attached to a rotating shaft, which is powered by an electric motor or a diesel engine. As the impeller rotates, it causes the liquid to be drawn in and expelled from the pump.
The benefits of positive displacement pumps include:
1. Reliability – Positive displacement pumps are reliable and can handle a wide range of liquids, including water, oils, fuels, and chemicals.
2. Efficient – Positive displacement pumps are very efficient and can achieve high flow rates with low horsepower requirements.
3. Durable – Positive displacement pumps are durable and can withstand high pressures and temperatures.
4. Easy to maintain – Positive displacement pumps are easy to maintain and typically have a long lifespan.
Applications for positive displacement pumps include:
2. Agricultural – Positive displacement pumps are used in many agricultural applications, including irrigation, livestock feeding, and grain handling.
3. Domestic – Positive displacement pumps are used in many domestic applications, including water supply, septic systems, and pool and spa circulation.
