ZGT Hydraulic Damping Spring Vibration Isolator
ZGT Hydraulic Damping Spring Vibration Isolator is a high-performance vibration control solution designed for heavy-duty mechanical equipment. It combines high-elasticity spring suspension technology with built-in hydraulic damping to effectively absorb and dissipate vibration energy, reduce structural vibration transmission, and minimize operating noise.
It is widely used for punching machines, water pumps, chillers, rooftop air conditioning units, ventilation fans, cooling towers, compressors and other industrial equipment where stable operation and low noise are required.
With a load capacity range of 1000–8000 kg per unit, ZGT isolators provide flexible vibration isolation solutions for different equipment weights and installation conditions. The spring system supports excellent static load performance, while the hydraulic damping mechanism improves vibration attenuation, reduces resonance impact, and enhances equipment stability during start-up and operation.
Why Choose ZGT Hydraulic Damping Spring Vibration Isolator?
1. Effective Vibration Isolation and Noise Reduction
Industrial equipment such as motors, pumps, compressors, and punching machines generate continuous vibration during operation. These vibrations can be transmitted through foundations and structures, causing:
- Equipment damage
- Structural vibration
- Operating noise
- Reduced machine accuracy
- Shortened service life of components
ZGT vibration isolators effectively reduce vibration transmission through a combination of spring isolation and hydraulic damping technology.
The system helps to:
- Absorb mechanical vibration
- Reduce vibration transmission to the foundation
- Lower operating noise
- Improve equipment stability
- Protect surrounding structures
2. High Elastic Spring + Hydraulic Damping Technology
Traditional spring mounts mainly rely on spring elasticity for vibration isolation. However, during equipment start-up, shutdown, or sudden load changes, excessive movement may occur.
ZGT hydraulic damping spring isolators integrate a damping system to control vibration movement and quickly consume vibration energy.
Main advantages:
✔ Reduce equipment movement
✔ Control resonance amplification
✔ Absorb shock loads
✔ Improve vibration attenuation performance
✔ Provide smoother equipment operation
This makes ZGT suitable for heavy-duty and dynamic-load applications.
3. Heavy Load Capacity for Industrial Applications
ZGT series vibration isolators are designed for medium and heavy equipment applications.
Load capacity:
1000 kg – 8000 kg per unit
Suitable for:
- Industrial pumps
- Large chillers
- HVAC systems
- Compressors
- Cooling towers
- Ventilation equipment
- Punching machines

Chillers and Rooftop HVAC Units
Large HVAC equipment, chillers, and rooftop air conditioning units often create vibration through compressors, fans, and motors.
ZGT isolators help reduce:
- Compressor vibration
- Fan vibration
- Structural noise transmission
- Building vibration
They are ideal for commercial buildings, factories, hospitals, and industrial facilities.
Pumps, Compressors and Rotating Equipment
Rotating equipment may produce vibration caused by motor imbalance, shaft rotation, and mechanical operation.
Installing ZGT vibration isolators can:
- Improve equipment stability
- Reduce mechanical stress
- Protect bearings and components
- Extend equipment service life
Frequently Asked Questions (FAQ)
Q1: What is a ZGT Hydraulic Damping Spring Vibration Isolator?
A ZGT Hydraulic Damping Spring Vibration Isolator is a high-performance vibration control device that combines a spring isolation system with hydraulic damping technology.
The spring element supports the equipment load and provides vibration isolation, while the hydraulic damping system absorbs vibration energy and controls excessive movement.
Compared with conventional spring mounts, ZGT isolators provide better control during:
- Equipment start-up
- Shutdown conditions
- Sudden load changes
- Dynamic vibration environments
They are especially suitable for heavy industrial equipment requiring both vibration reduction and operational stability.
Q2: Is ZGT vibration isolator a standard product?
No. ZGT vibration isolators are mainly designed as custom-engineered products.
Different machines have different vibration characteristics, operating speeds, weights, and installation requirements. A fixed standard size cannot guarantee the best vibration isolation performance.
The design is customized based on:
- Equipment weight
- Number of support points
- Operating RPM
- Vibration direction
- Installation conditions
- Required isolation efficiency
Each ZGT isolator can be engineered according to the customer’s actual application.
Q3: What information is required for customization?
To select the correct ZGT vibration isolator, customers are recommended to provide:
- Equipment type
- Equipment total weight
- Quantity of isolators required
- Equipment dimensions
- Installation space limitations
- Operating speed (RPM)
- Vibration requirements
- Environmental conditions
If complete technical data is unavailable, customers can also provide equipment photos, nameplates, or drawings. Our engineering team can assist with selection.
Q4: What is the load capacity of ZGT isolators?
The standard customized load range of ZGT hydraulic damping spring isolators is:
1000–8000 kg per unit
The actual capacity depends on:
- Equipment weight distribution
- Number of mounting points
- Spring configuration
- Required safety factor
For heavier equipment, multiple isolators or special structures can be designed.
Q5: What is the difference between hydraulic damping isolators and normal spring isolators?
A normal spring isolator mainly relies on spring elasticity to isolate vibration. However, when equipment starts or stops, the spring may allow larger movement.
A hydraulic damping spring isolator adds damping control, which provides:
- Faster vibration reduction
- Less equipment movement
- Better stability
- Improved shock absorption
- Reduced resonance effects
Therefore, hydraulic damping isolators are more suitable for large, dynamic, and precision equipment.
Q6: Can ZGT isolators be used outdoors?
Yes.
ZGT isolators can be customized for outdoor applications such as:
- Rooftop HVAC units
- Cooling towers
- Outdoor fans
- Industrial equipment areas
Depending on the environment, different surface treatments can be provided:
- Anti-corrosion coating
- Galvanized steel structure
- Stainless steel components
The final design depends on the installation environment and customer requirements.
Q7: How long is the service life of ZGT vibration isolators?
The service life depends on:
- Equipment operating conditions
- Load cycles
- Environmental factors
- Installation quality
- Maintenance conditions
With proper selection and installation, ZGT vibration isolators are designed for long-term industrial operation and reliable vibration control.
