A Pulsation Damper is primarily used to reduce and control pressure pulsations and vibrations in the flow of liquids or gases. It plays an important role in many industrial applications.
Pump accessories play a vital role in optimizing the performance, accuracy, and longevity of dosing and metering pumps. These components not only enhance the efficiency of pump operations but also protect the pump and its system from potential damage. Below are some key accessories that contribute to better pump performance and system protection:1. Back Pressur
The back pressure valve can stabilize the flow rate of the metering pump while maintaining stable pipeline pressure, ensuring metering accuracy. A pulsation dampener can effectively prevent pipeline vibration caused by pulsation
The pulsation damper is one of the indispensable accessories for the use of metering pumps. The following is an analysis and solution of the failures that may be encountered during the use of the back pressure valve.
There are several things to note when using a pulsation dampener:Due to the harsh working environment of construction machinery, the dampener has high sealing performance, so it should be protected from dust and other debris. Also, avoid scratching or damaging the piston rod surface of the dampener with sharp tools, and do not apply paint or corrosive chemicals
The structure of the stainless steel flow calibration column without sheath is simple, with a transparent tube in the middle and metal material at both ends. The connection between the metal and the transparent tube is usually a threaded or threaded rod fixed connection.
Technical Spec.:
Volume: 20ml-40L, customizable according to requirements
Connection method: threaded, flange, quick-connect, etc.
Can be made into: two end pipes, bottom pipe with top threaded plug
Materials:
Transparent tube materials: transparent PVC, acrylic glass, quartz glass (standard configuration for below 500ml), high borosilicate glass (standard configuration for 1L or more)
Liquid contact materials: stainless steel, carbon steel, PVC, PVDF, etc.
The jacketed flow calibration column refers to adding a protective cover outside the transparent tube to prevent it from being scratched or damaged by impact, making it particularly suitable for use in harsh environments. Usually, a metal material Jacket is used, which can effectively protect the internal transparent tube, increase its service life, and improve the product grade.

The Bladder type pulsation damper isolates the medium and pre-charged gas from the airbag. The airbag has high sensitivity and can effectively eliminate pulsation. It can withstand high pressure (the maximum pressure resistance of the airbag pulsation damper produced by our company is 40 MPa).
The features of airbag/Bladder pulsation damper:
During operation, the compressed liquid in the pipeline compresses the airbag, causing the airbag to contract and then expand to compensate for the pressure loss in the pipeline, thus achieving a buffering effect. Compared with the diaphragm type, the airbag pulsation damper has higher sensitivity, better buffering effect, and can be made with a larger volume. However, because the airbag material is generally rubber, its range of use is not as wide as the diaphragm type. The simple selection method is to multiply the volume of each pump stroke by 10 to obtain the minimum volume that can reduce 90% of pulsation.
Proportional relief valves, also known as proportional pressure control valves, are hydraulic valves that are designed to maintain a constant pressure in a hydraulic system, regardless of changes in the system's flow rate. They operate by diverting excess fluid flow away from the system's working components and back to the reservoir, thereby maintaining a constant system pressure.
Proportional relief valves are typically used in hydraulic systems that require precise pressure control, such as in machine tools, injection molding machines, and metalworking machinery. They can also be used in mobile hydraulic applications, such as construction equipment and agricultural machinery.
In addition to maintaining a constant pressure, proportional relief valves can also provide other features, such as temperature control, pressure sequencing, and remote control options. They are available in a variety of sizes and configurations, and can be customized to meet specific system requirements.
