Product Introduction
Mechanical seal (also known as sealing ring) is a key sealing component installed between the impeller and the pump body, which reduces fluid leakage from the high-pressure area to the low-pressure area through a precisely matched annular gap (usually 0.2-0.5mm). Its design directly affects the efficiency (which can increase by 5% -8%) and lifespan of the water pump, and is suitable for rotary fluid equipment such as centrifugal pumps and mixed flow pumps.
Product Features
Material innovation
Using silicon carbide/tungsten steel composite material, the hardness reaches HRA90, and the wear resistance is three times higher than traditional cast iron
Structural optimization
Maze groove design reduces leakage to 30% of conventional structures
Adaptability
Modular size (DN50-DN600) supports quick replacement
Key points of production
1. Casting
Vacuum melting casting process controls porosity ≤ 0.5%
2. Machining
Radial runout tolerance ≤ 0.02mm (GB/T1804-m level)
3. Heat treatment
Gradient quenching results in a surface hardness greater than 10% of the internal hardness
Advantage analysis
Energy saving: Reduce volume loss by 10% -15%
Maintenance cost: Extended lifespan to 20000 hours (8000 hours for regular products)
Safety: Explosion proof design certified by ATEX
Application scenarios
Nuclear power field: main circulation pump
Our factory
Hebei Jutong Pump Industry was founded in 2021 based on 35 years of pump technology accumulation, and quickly realized the full-chain production of slurry pumps, valves, and mechanical seals; in 2022, it passed the CAE simulation system and intelligent casting to obtain ISO/CE/MA triple certification, opening up the high-end market of mine environmental protection; domestic projects have accumulated 50,000+ hours of operation to verify equipment reliability, and 85% repurchase rate to build customer stickiness; in 2024, it will export Chilean copper mines and UAE desalination projects through multilingual digital platforms; in 2025, it will cover 50 countries along the "Belt and Road" and the goal of earning 50 million foreign exchange is imminent.
