Plunger Pump vs Piston Pump: Industrial Pump Types
Introduction to Plunger and Piston Pumps
Plunger pumps and piston pumps are both types of positive displacement pumps commonly used in industrial applications. The pumps use reciprocating plungers or pistons to create a positive displacement of the fluid being pumped. A plunger or a piston is sealed against the pump cylinder with a set of packing or seals. The plunger or piston moves back and forth in the cylinder, drawing fluid in through an inlet valve and forcing it out through a discharge valve.Typical Uses of Plunger and Piston Pumps
Plunger pumps are typically used in high-pressure applications where a steady flow rate is required. They are often used in oil and gas drilling, water treatment, and chemical processing. On the other hand, Piston pumps are often used in applications where a high flow rate is required, such as in agricultural irrigation, construction, and mining.To Learn More：What is Plunger Pump?

Key Differences between Plunger and Piston Pumps
-
Material
Plunger pumps typically use a ceramic or stainless steel plunger, while piston pumps typically use a metal piston. -
Sealing
Plunger pumps typically use a set of packing or seals to seal the plunger against the cylinder, while piston pumps typically use a set of rings or seals to seal the piston against the cylinder. -
Pressure vs. Flow
Plunger pumps are typically used in high-pressure applications where a steady flow rate is required, while piston pumps are often used in applications where a high flow rate is required. -
Maintenance
Plunger pumps are generally easier to maintain than piston pumps, as they have fewer moving parts and are less likely to suffer from wear and tear.
Making the Right Pump Choice
Overall, both plunger and piston pumps have their own unique advantages and disadvantages, and the choice of which type of pump to use will depend on the specific requirements of the application.Deep Dive：Plunger Pump Applications: How Does a Plunger Pump Work?
