How Hydraulic Pump Work: Types & Applications

The hydraulic pump converts mechanical energy into fluid power to power hydraulic systems. These pumps help several industries operate their heavy lifting and automated systems. Companies can pick the right pumps for their needs because they understand hydraulic pump technology. 

This article describes hydraulic pump technology through its working principles and types while showing examples from THM Huade Hydraulics. 

How Hydraulic Pumps Work

The hydraulic pump forms an airless chamber to pull hydraulic fluid into the system. The pump utilizes hydraulic fluid to generate high pressure that moves through the system to operate equipment. The hydraulic system uses this method to power lifting and rotating operations with precise control. 

Hydraulic pumps work best when connected to hydraulic pump motors to transform hydraulic power into mechanical energy for reliable performance. Before buying a hydraulic pump motor you need to compare its efficiency rating with its power output and system compatibility. 

Types of Hydraulic Pumps

Different hydraulic pump designs exist for different working needs. Here are the main hydraulic pump types used today: 

1. Radial Piston Pumps

Radial piston pumps deliver strong pressure output and stand up well under heavy use. Each piston inside the pump moves in a circle to rotate on a single power shaft. As the shaft turns the pistons extend to absorb fluid before moving back to push it out with high force. 

Applications:

• Industrial presses 
• Machine tools 
• Injection molding machines 

2. Servo Pumps 

Standard hydraulic pump parts work together with servo motors to adjust the delivery rate and output pressure of servo pumps. These pumps achieve the best possible energy savings while handling various operating conditions and speed adjustments. 

Applications:

• CNC machinery 
• Plastic injection molding 
• Automation systems 

3. Axial Piston Pumps

The axial piston pump contains a set of pistons rotating inside a cylinder block. People continue to choose these pumps because they save energy while taking up minimal space.

Applications: 

• Marine applications 
• Heavy duty industrial machinery 

4. Gear Pumps

Simple and affordable gear pumps deliver reliable performance. The system transfers hydraulic fluid through two perfectly aligned gears. The pumps produce sufficient power and volume but do not reach the performance level of piston pumps. They deliver suitable hydraulic power for tasks that do not require high performance. 

Applications: 

• Agricultural equipment 
• Hydraulic power units 
• Lubrication systems 

5. Vane Pumps 

A chamber fills with hydraulic fluid as rotating vanes turn inside it. These pumps operate silently and provide their power at lower and middle hydraulic pressure levels.

Applications: 

• Automotive power steering 
• Plastic processing machines 
• Industrial hydraulic systems 

6. Pump Motor Assembly 

A pump motor assembly brings hydraulic pump and motor functions into a single integrated unit. These combined units deliver hydraulic power while moving parts with high efficiency in applications that need both functions. 

Applications: 

• Mobile machinery 
• Conveyor systems 
• Hydraulic presses 

Applications of Hydraulic Pumps

Hydraulic pumps deliver good performance in manufacturing and aerospace industries plus construction work. The main industries depend on hydraulic pumps to perform essential tasks. 

1. Construction & Earthmoving Equipment

• Excavators 
• Bulldozers 
• Loaders 

2. Manufacturing & Industrial Automation 

• Press machines 
• CNC machining centers 
• Injection molding machines 

3. Agriculture & Forestry 

• Tractors 
• Harvesters 
• Log splitters 

4. Automotive & Material Handling 

• Power steering systems 
• Forklifts 
• Cranes 

Choosing the Right Hydraulic Pump 

The hydraulic pump motor you need depends on these main factors: 

1. Make sure the pump motor picks the correct power amount since your system requires a specific amount of pumping power. 

2. Servo pumps help users save energy when used in their proper applications. 

3. The tough operating conditions require hydraulic pumps made of durable materials with built-in protection. 

4. Compatibility – Check compatibility with existing hydraulic components.
