Real challenges, engineering solutions, measurable results.
Molten salt pump at 450°C, shaft 65mm, 1500rpm. Special alloy bearings suffered frequent seizure, 3-month average life.
Custom high-purity carbon graphite bearings with antimony impregnation, optimized clearance for 450°C operation.
Chocolate mixer, shaft 30mm, 200rpm, 80°C. Copper bushings + food-grade grease caused copper ion and grease contamination.
Replaced with FDA-grade resin-impregnated carbon graphite bushings — completely oil-free self-lubricating design.
Centrifugal pump handling corrosive chemicals, shaft 50mm, 1450rpm, 80-120°C. PTFE seals leaked every 3 months.
Custom carbon graphite mechanical seal face with chemical-resistant resin impregnation, paired with SiC mating face.
Seawater pump, shaft 60mm, 1750rpm. Copper bearings + rubber seals corroded in seawater, replacement every 6 months.
Marine-grade carbon graphite bushings with special anti-corrosion impregnation + EPDM elastomer seals.
Large circulating water pump, shaft 120mm, 990rpm, 60-95°C. Tin bronze bearings wore rapidly, monthly maintenance.
High-hardness carbon graphite bearings with anti-abrasion impregnation, designed for sandy/particulate water conditions.
