50Pressure pump seal for plunger pump
The pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.
The application medium in the high-pressure cleaning machine is water, and the sealing parts need to meet the demand of increasing pressure. This type of seal originates from hydraulic equipment. In general, the shaft radial seal is mainly used on the gearbox. However, such seals are difficult to be used in water pumps, hot water equipment and other products. The main reason is that the service life is very short, and there is also a risk of water entering the oil chamber due to poor sealing effect. In addition, excessive slow relative movement of the seals can cause severe wear to the plunger.
In order to solve the above problems, we have developed a new sealing system, so that the seal can play a good sealing effect in water and the service life is greatly increased. Such a sealing system is adopted in the water pump, which effectively prevents the damage caused by water leakage and the failure of the water pump caused by the plunger friction overheating. Through detailed data analysis, the test shows that the sealing system can still ensure the normal operation of the system even under the conditions of large pressure change, high temperature and low lubrication. With such a sealing system, the high-pressure cleaning machine can work under the most severe working conditions.

The water pump seal D1 is composed of one or couple of fabric reinforced Chevron V rings (DM), back up ring (DD) and header ring (DS) for plunger sealing.
V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.
Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.
Pack off seal or Secondary Seal Assemblies is installed in the lower seal area of the Casing Spool or Tubing Head.
This product can fully meet the pressure working conditions of current hydrogen compressor transportation equipment, ranging from 0 to 90MPa, and the sealing element will not extrude and deform, with good sealing performance.
JST's RGD (Rapid Gas Decompression) o ring can be applicated in high and low temperature environment with high pressure. It is widely used in detection and drilling equipment, completion equipment, underwater valves and pumps, compressor ect.
DAS Compact Seal is a double-acting seal and guiding element comprising an elastomeric profile seal ring, two back-up rings and two guide rings.
Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
