Piston Pumps

Piston pumps are a type of positive displacement pump that use reciprocating pistons to move fluids. These pumps are known for their ability to generate high pressures and handle a wide range of fluids, making them essential in various industrial applications. From water pumping to vacuum generation, piston pumps offer reliable and efficient performance across diverse sectors.

Types of Piston Pumps

Single Piston Pump

A single piston pump consists of one piston moving back and forth within a cylinder. These pumps are simple in design and suitable for low to medium flow rate applications.

Multi-Piston Pumps

Multi-piston pumps, such as the Edwards 612J piston pump, use multiple pistons to increase flow rate and provide smoother output. They are commonly used in high-pressure and high-volume applications.

Rotary Piston Pumps

Rotary piston pumps combine rotary and reciprocating motion, offering efficient operation and good vacuum performance. These pumps are often used in industrial vacuum systems.
