Product Description
Griffco Pulsation Dampeners
The Griffco Pulsation Dampeners improve the performance of chemical-feed and metering-pump systems. Moreover, they reduce pressure fluctuations created by positive-displacement pumps.
A dosing pump usually delivers chemicals in repeated pulses. Consequently, the discharge piping may experience vibration, pressure surges and uneven flow.
The pulsation dampener absorbs energy from each pressure wave. As a result, the system delivers a smoother and more continuous chemical flow at the injection point.
Improve Chemical Dosing Performance
Uneven discharge flow can affect dosing accuracy and system reliability. Therefore, a correctly sized pulsation dampener helps stabilise the chemical feed.
In addition, smoother flow improves the operation of important system components, including:
- Injection valves
- Back-pressure valves
- Pressure gauges
- Flow meters
- Control instruments
- Discharge piping
- Chemical injection quills
Moreover, reduced pulsation can limit vibration and operating noise. Consequently, the system places less stress on fittings, instruments and piping connections.
Key Benefits of Griffco Pulsation Dampeners
Griffco pulsation dampeners provide several practical advantages:
- Reduce harmful pressure waves
- Smooth positive-displacement pump output
- Support continuous chemical dosing
- Improve chemical-feed consistency
- Protect discharge piping and fittings
- Reduce vibration and operating noise
- Help control water hammer
- Reduce stress on gauges and instruments
- Offer plastic and metal construction options
- Support standard and high-pressure applications
- Provide several connection styles
- Offer multiple chemical-resistant materials
- Include several diaphragm material options
- Support a wide range of dampener volumes
Together, these benefits improve dosing-system reliability. Moreover, they may reduce maintenance requirements and equipment downtime.
Available Sizes and Connections
Griffco offers several connection sizes for different chemical-feed systems.
Available sizes may include:
- ½ inch
- ¾ inch
- 1 inch
- 2 inches
In addition, available connection styles include:
- NPT threaded
- BSPT threaded
- Union
- Flanged
- Socket connections on selected models
Therefore, users can integrate the dampener into many new or existing dosing systems.
However, pipe size alone does not determine the correct dampener capacity. Instead, users should consider pump displacement, pressure and pulsation-control requirements.
Pressure and Temperature Capabilities
Plastic Griffco pulsation dampeners can support pressures up to 150 PSI, depending on the selected material and configuration.
Meanwhile, selected metal and high-pressure models can support significantly higher system pressures.
Temperature limits also depend on the body and diaphragm materials. For example, PVC models suit lower operating temperatures, while PVDF, Noryl and metal configurations may support higher temperatures.
Therefore, users should confirm both pressure and temperature requirements before ordering.
Chemical-Resistant Material Options
Different chemicals require compatible body and diaphragm materials. Consequently, Griffco offers several construction options.
Available Body Materials
- Noryl
- PVC
- Polypropylene
- PVDF
- 316 stainless steel
Available Diaphragm Materials
- EPDM
- Viton
- Hypalon
In addition, selected configurations may include brass or stainless-steel charging components.
As a result, Griffco pulsation dampeners can support many acids, alkalis, disinfectants and water-treatment chemicals.
However, chemical concentration and temperature can affect material compatibility. Therefore, users should complete a compatibility review before final selection.
How a Pulsation Dampener Works
The dampener contains a flexible diaphragm that separates the process chemical from a compressed gas chamber.
When discharge pressure rises, chemical enters the dampener and compresses the gas. Therefore, the unit absorbs part of the pressure pulse.
When pump pressure falls, the compressed gas pushes the stored chemical back into the discharge line. As a result, the injection flow remains more consistent.
Moreover, the diaphragm prevents direct contact between the chemical and the gas charge. Consequently, the dampener maintains effective separation during operation.
Correct Installation and Sizing
Install the pulsation dampener on the pump discharge line. Moreover, place it as close to the dosing pump as practical.
Correct sizing depends on several factors:
- Pump type
- Pump displacement per stroke
- Number of pump heads
- Average operating pressure
- Minimum and maximum pressure
- Required pulsation reduction
- Dampener pre-charge pressure
- Chemical compatibility
Therefore, users should not select a dampener only by connection size.
In addition, the pre-charge pressure must match the system conditions. Otherwise, the dampener may not absorb pressure fluctuations effectively.
A properly sized and charged unit provides better pulsation control. Consequently, it helps protect the complete chemical-feed system.
Griffco Pulsation Dampener Applications in the UAE
Griffco Pulsation Dampeners suit many UAE applications, including:
- Water and wastewater treatment
- Reverse osmosis systems
- Desalination facilities
- Cooling-tower chemical dosing
- Boiler-water treatment
- Swimming pools and aquatic facilities
- Chlorination systems
- Chemical-processing plants
- Oil and gas chemical injection
- Food and beverage water treatment
- Industrial chemical-feed skids
- Municipal water systems
For example, a dampener can smooth sodium hypochlorite dosing in a disinfection system. Similarly, it can reduce fluctuations during antiscalant or pH-control chemical injection.
Moreover, stable pressure can improve instrument readings. As a result, operators can monitor the dosing process more accurately.
