Dongsuh Industrial Co., Ltd. has officially registered a new patent for an upgraded Hydraulic Sealing Device for Pumps, further solidifying our technical leadership and R&D capabilities.
When the drive shaft rotates, oil injected into the oil inlet cover moves along the internal oil guide toward the inflow prevention sealing section. This mechanism effectively counters internal pressure within the stuffing box to prevent fluid leakage. With this advanced design, Dongsuh Industrial continues to deliver reliable, high-performance sealing solutions to meet demanding industrial needs.
