Pulse dampers can smooth out pipeline pulsations caused by displacement pumps such as plunger pumps and diaphragm pumps, and eliminate water hammer phenomena in the system. They isolate gas from liquid in the pipeline through corrosion-resistant diaphragms, smooth pipeline pulsations through changes in chamber volume, and store and release energy from pressurized liquid. This series of products is widely used in industries such as chemical, water treatment, food and beverage, electricity, papermaking, textile, and fluid machinery.

Features:

Diaphragm type pulsation dampers can reduce pulsation generated by reciprocating pumps such as metering pumps or diaphragm pumps by 95%. They can pre charge the system pressure by about 50-70% before use (70% before installing the pump and 50% after installing the pump), avoiding water hammer in the system, reducing pipeline vibration, stabilizing flow, and protecting precision instruments.

Diaphragm type pulse damper model:

LGMZ-4.0L/LGMZ-P4.0L（DN40/DN50）

Main functions:

1. Eliminate the harm of water hammer to the system.

2. Reduce the peak value of flow rate fluctuations to ensure the correct display of the pump outlet pressure gauge.

3. Reduce the impact of pressure fluctuations on pipelines, elbows, and joints.

4. Absorb the pulsation of the pump, create a good working environment for it, and improve the working performance of the pump.

5. Allow the system to use smaller pipe diameters to reduce costs.

6. When used in conjunction with back pressure valves, it can make the pressure fluctuations in the pipeline close to zero.

7. Emergency or rapid energy storage to reduce system energy consumption

Notes:

The high operating pressure of the diaphragm pulsation damper Z is 1.6MPa for PVC and PP materials. Overpressure use is prohibited to avoid the danger of shell rupture. Z has a high operating temperature of 75 ℃. The low operating temperature of Z is 5 ℃, and the operating temperature is 10-45 ℃. PVDF, PC, SUS304 can withstand higher temperatures.

During the installation process, collisions should be avoided to prevent the shell from breaking. Sufficient space should be reserved around the pulsation damper during installation to facilitate pre filling of the damper with gas and future maintenance and adjustment. A shock-absorbing material should be placed between the pulsation damper and the fixed bracket to absorb the vibration energy of the pulsation damper housing and prevent co vibration.

Pre charge with nitrogen or argon gas before use, with a pressure of 50% -70% of the average system pressure. If installed at the pump outlet, it is recommended to pre charge 50% of the pressure. If installed at the pump inlet, it is recommended to pre charge 70%. If not used for a long time, the pre charge gas should be released to extend the diaphragm life. The material of the pulsation damper diaphragm is corrosion-resistant fluororubber. Do not pre charge with oxidizing gases (such as oxygen and air), otherwise it will accelerate the oxidation rate of the rubber and reduce the service life of the diaphragm.

When in use, the pressure gauge pointer should swing slightly. If the swing is too large, it indicates that the pre charge gas pressure is too low or the selection is too small. If it does not swing, it indicates that the pre charge gas pressure is too high or the pipeline is not connected.
