TK078DAM stuffing box is exclusive shaft seal base for 6/4-TKAH/AHR-E/D slurry pump, forming complete packing sealing assembly with D075 shaft sleeve, D118 lantern ring and D044 split packing gland. Two types available: standard TK078DAM and high-seal TK078DAMHS1. Independent flushing water inlet is reserved on side wall to feed clean cooling & slurry isolation water. Materials include grey cast iron D21, high chrome A05 alloy, 304/316 stainless steel. All dimensions fully follow OEM drawings for direct interchange, ideal for heavy-duty mining abrasion and power plant desulfurization corrosion conditions. Integrated OEM casting with precise tolerance, seamless fit for full sealing set Manufactured strictly per6/4-TKAH/AHR-E/D original drawings, accurate inner cavity, flange and positioning slot, no misalignment or leakage gap after assembly, fully compatible with all D-series seal components. Independent side flushing channel with 360° uniform water circulation for stable cooling & slurry isolation Dedicated side water inlet connects internal annular tank, clean water wraps sleeve and packing to build water barrier against slurry penetration, dissipate friction heat and prevent packing carbonization under high temperature. Extended large-capacity packing cavity holds multi-layer packing for reliable sealing under high pressure Sufficient cavity depth accommodates combined multi-layer packing and lantern ring, effectively reduce slurry leakage during high-concentration high-pressure pumping. Thickened casting body, erosion & pressure resistant, deformation & crack free for long-term operation Thick wall structure resists continuous sand erosion and medium pressure impact; high chrome version owns much longer service life than ordinary cast iron boxes. Matched with D044 split gland, packing replacement without rotor disassembly Cavity opening perfectly fits split gland design, maintenance without removing full rotor assembly, fast packing replacement to cut production downtime significantly. Standard & high-seal HS1 dual versions for different leakage control standards Standard TK078DAM for general mining; extended-cavity TK078DAMHS1 for strict environmental scenarios such as desulfurization and chemical industry with zero slurry overflow demand. Full material range covering abrasive and corrosive harsh working conditions Cast iron for low-cost general use, high chrome for severe abrasion, stainless steel for acid & alkali medium, flexible material selection to lower long-term equipment maintenance cost. Sufficient stock for standard sizes, custom machining available with stable bulk order lead time Standard TK078DAM and TK078DAMHS1 in stock; customized extended/thickened stuffing box available, stable mass production schedule for large quantity orders.
