What are the Main Structures of Piston Pump?

A piston pump can be defined as a machine used to transfer liquid or compressed gas from one point to another. This is a positive displacement pump with a high pressure seal reciprocating with the piston. Plunger pumps are robust, efficient and versatile. Machining, drilling, etc. are just a few of the application areas where plunger pumps are used. Piston pumps are used to transport liquids or compressed gases.

It is a hydraulic pump with stable performance and high efficiency. In this article, we will introduce the structure of piston pump.

As shown in the above figure, the ATO industrial automation piston pump consists of different parts. Each part is explained in brief.

• Intake. This is part of the pump where the input is given. It may be liquid or high-pressure gas etc.
• Port plate. This acts as the separating medium between the input port and output. The compressed gas or liquid is sent out through this medium.
• Discharge. This forms the output of the pump.
• Rotating barrel. This is a dynamic part of the pump, in which the pistons are inserted in their specific slots. When the barrel rotates, along with that the pistons rotate and displace the liquid or compressed gas.
• Piston. This forms the most important part of the pump. They are the interfacing medium between the nonrotating swash plate and the barrel. Pistons do have a spring-like system such that they reshape their size when the barrel revolves.
• Nonrotating swash plate. This is the interface for the external system and pistons. The pistons reshape themselves, get compressed when they come down under a force by the swashplate. The swashplate is a non-rotating part. It is fixed to the shaft.
• Shaft. The shaft is coupled to the rotating barrel and the swashplate. On the shaft, the complete assembly is house.

Due to its robustness, it has versatile applications. A few of them are mentioned as high pressure cleaning, water hydraulics, oil hydraulics, process technology, water injection, water cutting, drilling service, industrial, commercial, hydraulic pressure testing, etc.
