An Introduction to Plunger Pumps

Plunger Pumps

Plunger pumps are one of the oldest pump designs in existence, but their advanced engineering and reliable performance have made them a go-to choice for many industries. In this blog post, we will explore what exactly a plunger pump is, how it works, and why it is so popular among professionals who need to move liquids quickly and reliably.

What Is A Plunger Pump?

A plunger pump is a type of positive displacement pump that uses reciprocating plungers to transfer fluids from a low-pressure area to a high-pressure area. The plunger acts like a piston, moving back and forth in an enclosed cylinder to create suction at the inlet side of the pump while simultaneously pushing liquid out through the outlet. The number of plungers on the pump, as well as its size and pressure requirements, can vary depending on the application.

How Does It Work?             

A plunger pump works by creating suction at its inlet port which draws fluid into its cylinder chambers. The fluid then builds up pressure until it is forced out through the outlet port. This process is repeated with each stroke of the plunger until all of the fluid has been transferred from one side of the pump to another. Because plunger pumps are self-priming, they can be used in both open-loop systems where suction lift is required and closed-loop systems where priming is not necessary. This makes them very versatile for use in both industrial applications and residential settings alike.

The main advantage of using a plunger pump over other types of pumps is its ability to handle large volumes of fluids without losing efficiency or reliability. Additionally, a plunger pump’s design allows it to run more smoothly than other types of pumps since there are no rotating parts that can cause wear and tear over time. As such, plunger pumps require less maintenance than other types of pumps making them ideal for long-term use in demanding environments.


Plunger pumps are an effective way to move large volumes of liquids from one point to another with minimal risk or maintenance requirements. Their simple design makes them easy to set up and operate while their self-priming capabilities make them suitable for both open-loop and closed loop applications alike. Whether you’re an industry professional or just a homeowner looking for reliable equipment for your next DIY project, consider using a plunger pump – you won’t regret it!
