THM – A4VTG – Variable Displacement Piston Pump

Description

THM – A4VTG – Variable Displacement Piston Pump

This series is a swash plate-controlled axial piston pump from THM, designed for use in hydrostatic closed-loop systems. For use in medium-duty applications, this pump supplies precise control, high efficiency and great reliability in tough hydraulic environments.

 

Overview

The A4VTG pump is designed for hydrostatic transmissions that benefit from a small footprint, flexible flow and quick response. Thanks to its advanced design and strong construction, the pump fulfills the important requirements of hydraulic machinery used in construction, agriculture, handling materials and manufacturing.

 

Working Principle

The A4VTG axial piston pump follows the swash plate design. Pistons in the rotating cylinder block are controlled in angle by the swash plate. Reciprocating actions of the pistons are caused by the rotation of the cylinder block by the drive shaft.

1. When the swash plate is tilted, the pump displacement can be controlled. The bigger the tilt, the further the piston moves and so the more fluid can be pumped.
2. In the neutral position, the swash plate allows the flow to switch between the two directions without any problem.
3. The output flow is changed by how fast the drive is turned and how far the swash plate is tilted, so the pump can flow from zero to its maximum amount.
4. This design is intended for use in hydrostatic closed circuits, where the fluid goes from the pump to the motor and back again, without any reservoir in between.

 

Features

Swash Plate Design for high accuracy and the ability to change parameters.

• The system is designed for applications that need control in both directions and low energy consumption.
• The flow rate is determined by both the speed of the drive and the angle of the swash plate.
• Smooth switching of flow direction when the swash plate is in its neutral position.
• Dual Pressure Relief Valves: Keeps the pressure in the system safe and increases how long components last.
• The Integrated Boost Pump helps keep circuit pressure, pumps control oil and covers any internal leakage.
• The Valve helps maintain safe and efficient boost pressure.

Advantages of Using Our Hydraulic System Components

Hydraulic systems are important in many industrial and mobile applications, so selecting suitable parts can greatly boost efficiency, dependability and safety. The following are the most important benefits you can gain from our advanced hydraulic products and solutions:

 

1. Optimized Flow Control for Higher Efficiency

A major strength of our hydraulic components is that they can efficiently control fluid flow. This results in a major decrease in wasted energy. Traditional systems often end up with extra flow causing pressure to increase, heat to rise and the system to work less efficiently. Because our systems are designed for efficiency, they deliver only the flow and pressure that is actually needed. It results in less energy being used and less money spent over time, so it is both good for the environment and for industry finances.

 

2. Design for Spaces with Limited Space

There is often not enough space for industrial machinery and mobile equipment. Because of this, our hydraulic components are made to be as small as possible. Because they are compact, they suit places where space is at a minimum, but they still work well and are functional. The compact shape helps these motors be installed easily on factory equipment or on mobile construction equipment.

 

3. Made to Withstand Tough Conditions

Industrial and construction sites are typically very tough to work in. Our hydraulic systems are made to be durable. Because they are made from durable materials and sealed from contaminants, these parts are able to work well in tough situations, many cycles and extreme temperatures. Because of this, they last for a long time and need less maintenance and repair which saves money.

 

4. It is easy to integrate with many hydraulic components.

Designing our system with flexibility in mind is very important. The components are built so they are easy to combine with many hydraulic parts and accessories. It makes it easier to set up the system and to perform upgrades or repairs later. If you are setting up a new system or adding to an existing one, our components help the integration go smoothly.

 

5. Enhanced Safety with Built-In Pressure Relief Mechanisms

The safety of a hydraulic system is always a main concern. The components we use have pressure relief features designed to stop excessive pressure from building up. It prevents damage to equipment, keeps operators safe and increases the dependability of the system. They are necessary for following safety regulations and securing the plant for the long run.

 

Maintenance Tips

1. To make sure the A4VTG pump continues to function well, you should follow these maintenance tips.
2. Regular Inspection: Examine the system for leaks, strange sounds or overheating while it is working.
3. Use only good quality hydraulic oil and change it often to ensure it does not get polluted.
4. Change your filters as recommended to ensure your fluid is clean and the pump works well.
5. Check the swash plate regularly to make sure the controls are working well.
6. Integrated Boost Pump: Check that the boost pump is keeping the circuit pressure within the correct range.
7. Seal and O-ring Inspection: It is essential to replace seals and O-rings regularly to stop internal leaks.
8. Make sure that the pressure relief valves are set to the required pressure levels.

 

Conclusion

The Variable Displacement Piston Pump from THM – A4VTG is perfect for systems that need hydraulic components that are versatile, energy efficient and perform well. Because of its swash plate, smooth flow direction and strong protection, it can handle a variety of medium-duty tasks. Because the A4VTG series is designed for different pressure and displacement levels and is easy to maintain, it delivers reliable performance and a long life in many industries and mobile applications.

Go with THM – A4VTG to ensure your hydraulic circuits are highly controlled, precise and durable.
