The UPVC Air Chamber Pulse Damper is a high-performance pressure buffering device installed at the discharge side of metering or diaphragm pumps. By utilizing the compressibility of air within the chamber, it effectively absorbs pressure spikes and smooths out flow pulsations in industrial piping systems.
Key Features
Corrosion Resistance: Constructed from high-grade UPVC, making it ideal for handling aggressive acids, alkalis, and chemical reagents.
Cost-Efficiency: Features a simplified, robust design that provides a budget-friendly solution without compromising on operational reliability.
Integrated Protection: Includes a diaphragm-sealed pressure gauge that allows for real-time monitoring while protecting the internal gauge components from corrosive media.
Functional Characteristics
Simple structure and cost-effective.
Made of UPVC material with superior corrosion resistance.
Equipped with a diaphragm pressure gauge to prevent gauge corrosion.
Volume Selection of Air Damper
The minimum required volume of the pulse damper can be calculated by multiplying the metering capacity per stroke (ml) of the metering pump (or diaphragm pump) by 26.
| Volume (L) | Caliber | d (mm) | D (mm) | H (mm) | Diaphragm type H (mm) | Rated pressure (MPa) |
| 0.6 | DN15 | 20 | 85 | 266 | 330 | 1 |
| 0.9 | DN20 | 25 | 100 | 266 | 330 | 1 |
| 1.2 | DN25 | 32 | 110 | 286 | 351 | 1 |
| 2.2 | DN32 | 40 | 130 | 380 | 445 | 1 |
| 3.2 | DN40 | 50 | 162 | 398 | 465 | 1 |
| 5 | DN40 | 50 | 162 | 560 | 625 | 1 |
| 10 | DN50 | 63 | 162 | 925 | 1000 | 1 |
