MS PTFE Lined Stirrer

MS PTFE Lined Stirrer

The MS PTFE Lined Stirrer is a special-purpose industrial stirrer designed for highly corrosive chemical processes requiring high mechanical strength and chemical inertness. The stirrer consists of a mild steel (MS) core fully lined with PTFE (Teflon), combining structural rigidity with excellent corrosion resistance.

It is widely used in glass reactors, glass-lined vessels, and chemical process equipment where pure metal stirrers are unsuitable due to corrosion and solid PTFE stirrers lack sufficient strength.

Construction & Design

• Core Material: Mild Steel (MS)
• Lining Material: PTFE (Teflon) – virgin grade
• Shaft Design: Solid MS shaft with uniform PTFE lining
• Blade Types: Anchor / Paddle / Custom profile
• Surface Finish: Smooth, non-stick, pinhole-free
• Mounting: Compatible with mechanical seals, stuffing boxes, and drive couplings

Key Features & Benefits

• Outstanding chemical resistance to acids, alkalis, solvents, and corrosive media
• High torque capability suitable for viscous and dense fluids
• Wide operating temperature range up to 200°C
• Non-stick PTFE surface minimizes material buildup and contamination
• Long service life with reduced maintenance
• Custom-manufactured to suit reactor size and process conditions
