The hydraulic piston pump is a type of pump that holds together a very crucial task force for the hydraulic cylinder. The pumps seek to complete the task by following the rule of the hydrodynamic strategy. However, each variation of the hydraulic pump has many varieties of specific elements that stand out. Each specification looks forward to completing a specific task. 

Though the pumps have many specifications that work as their characteristics, they work toward achieving one single goal. The main aspect of the task is to convert the mechanical power into a hydraulic force using nothing but the mechanical force. The force generated using hydrostatic energy. Hydrostatic energy uses the power of flow and pressure. It is this flow that is utilized to create pressure in the pump outlet. 

The hydrostatic power utilizes Pascal’s law as an endowment to enhance the mechanism of the system. Each type of piston uses this particular law to enforce power. Depending on the variation, the amount of energy that is produced is managed. That is why it is a very crucial element of hydraulic cylinders. In this article, we will discuss the variation of hydraulic pumps and how it works. 

Types Of Hydraulic Pumps: 

Developing your idea around the basic parts of the hydraulic piston pump will help you understand where it needs servicing. Only by adhering to the basic functionality of the parts, you can determine your action. There are many types of pumps in the market. However, the one that is installed in your cylinder may deviate. 

Depending on your requirement, your choice of the pump will vary. You may need an axial piston pump or the radial one. That is why the installation process along with the servicing process requires a bit of understanding of the functionality of the parts. 

  • Radial piston pump: This specific pump uses the piston to function the whole mechanism. The piston extends in the radial direction to maintain the linearity of the effect. Hence the name radial piston pump came to be.
  • Inline axial piston pump: This type of piston pump borrows numerous variable compensation strategies to conserve more energy. 
  • Bent axis pump: Unlike the axial pump, this has fewer displacement techniques to incorporate while putting things in work. However, the functionality of the pump is all the more effective. 
  • Screw pumps: This type of pump uses fixed displacement along with two Archimedes’ screws. Those two screws are joined together in the same position to create linearity. It produces a high amount of flow and power. 
  • Gear pumps: Gear pumps are very economical for their volumetric capacity and efficient production of a result. That is why it is widely used. 
  • Rotary Vane pump: The mechanism is completed by using the positive displacement procedure to enhance the effectiveness of the product. 

How Does Hydraulics Piston Pumps Work? 

The mechanism of the pump uses a procedure in which it uses the equipment that is placed on the surface. The utility of the surface as a medium ensures the production of more high-pressure power through the fluid. The fluid is injected through the underlying pipes so that the manipulation of Rexroth piston pumps is done right. 

The method of oil production utilizes two parallel pipelines. One of the pipelines uses a powered liquid whereas the other is used for oil production. Sometimes a small tubing is installed in the larger one to systemize the piston pump. The power fluid consists of clean crude oil or any oil for that matter. It is sent through the hydraulic engine first. 

Coming from the high-pressure pump, through the platform, and finally to the large tubing. It makes the engine piston reciprocate which further generates the alternating movement of the oil pump piston working in the lower portion of the pump. It sucks the liquid and sends that to the upper part. The liquid is thus then subsided to the settling tank on the surface. It is then sent to the high-pressure pump for further cycling. 

Most Asked Question On The Internet:

The maximized amount of displacement produced by the hydraulic pump depends on the Well condition. Not only the Well condition but the tubing size, oil production, power of the fluid, etc.
Depending on the task you want the pump to complete, the power fluid will vary. Though closed power fluid is commonly used.
The advantages of using the piston pump are multifaceted. First and foremost, the piston pump is suitable to extract oil from the deep-seated bed of the ocean. The flexibility of the product provides the user to utilize the machine the way they want. And the variety of options to choose from only enhances its affectability.


The piston pumps are a crucial element of the hydraulic system which needs to be tended to. According to the regulations, the piston pump can work without maintenance for 12 years. However, a yearly inspection is required to maintain the production ability of the product.
