Customized Pressureless Sintered SSIC Bushing for Pumps

Silicon Carbide-Graphite Composite Bushing Product Introduction

Designed for stainless steel magnetic drive pumps, the SiC+Graphite composite bushing combines high-hardness silicon carbide with self-lubricating graphite, delivering both wear resistance and self-lubrication – a core component for leak-free pump operation.

Key Features

Technical Specifications

Design for Magnetic Pumps

• Precision clearance: 0.03-0.05mm ID/shaft gap (prevents fluid flashing)
• Anti-rotation grooves: Outer spiral channels improve coolant flow
• Fail-safe: SiC matrix provides backup support after graphite wear

Applications

• Chemical mag pumps: 31% HCl transfer, >20,000h service life
• Electroplating pumps: CrO₃ resistance, zero metal contamination
• Pharmaceutical pumps: FDA-compliant for WFI systems
