On February 18, 2025, the National Intellectual Property Administration announced that SEAD Pump (Zhejiang) Co., Ltd. had obtained a utility model patent for “A Wear-resistant Mechanical Seal Structure” (Authorization Announcement No.: CN 222502155 U). This technology, through innovative structural design, significantly improves the sealing performance of centrifugal pumps in industrial water pumps. It provides a new solution for the equipment reliability in application fields where the working conditions are prone to cause water – shortage and dry – running of mechanical seals.Innovative Structure Solves Industry Pain PointsAs indicated by the patent documents, this wear – resistant impeller features a new structural design. There are a lubrication cavity and an oil – seal groove within the oil – seal seat. When the pump is in operation and rotating, the grease in the lubrication cavity is spread between the rotating ring and the stationary ring of the mechanical
Seal, providing a lubricating effect. This enables the mechanical seal to endure dry – running for at least 8 hours without damage during trial operation or when there is a lack of water inside the pump chamber. Its dry – running lifespan is increased by over 20 times compared to that of ordinary mechanical seals!
The industry has broad application prospects.As the pioneer of the digital intelligent industrial pump category, since its establishment, SEAD PUMP Intelligence has set its sights high. Positioning its products to endow traditional industrial pumps with functions like intelligent sensing, remote control, and intelligent operation and maintenance. It is committed to solving the pain points of traditional industries through digital intelligence technologies and effectively creating value for users.
Therefore, this breakthrough in the patent for the wear – resistant mechanical seal structure marks a phased achievement for SEAD PUMP on the path of fulfilling its corporate vision.
At present, big data and AI technologies have become key areas for the upgrading of industrial equipment. As SEAD PUMP technologies are gradually applied to various types of pumps such as centrifugal pumps, pipeline pumps,sewage pumps, split – case pumps, fire pumps, single – stage double – suction centrifugal pumps, and end – suction centrifugal pumps.When applied in fields such as industrial water treatment, district heating, air – conditioning systems, building water supply, municipal drainage, energy, metallurgy, environmental protection, food cleaning, and the petroleum industry, these technologies will significantly reduce the operation and maintenance costs for users and promote the green and efficient development of the industry!
