The HWS Ceramic Mechanical Seal is a versatile and robust connector designed for use with stirrers in glass, metal, and coated materials. This innovative stirrer guide features an encapsulated ball bearing in stainless steel, ensuring reliable and safe operation even under challenging conditions. With its advanced design and high-quality materials, the HWS Ceramic Mechanical Seal provides unmatched sealing capabilities and longevity.
Key Features and Benefits
Universal Compatibility
The HWS Ceramic Mechanical Seal accommodates various stirrer materials, including glass, stainless steel, and Hastelloy. Its unique static seal prevents shaft damage during operation, making it particularly advantageous for use with coated stirrers (e.g., PFA, PTFE).
High Gas Tightness and Low Friction
Engineered for high gas tightness, the seal ensures smooth,
low-friction rotation across a wide speed range (up to 800 r/min), providing long operational efficiency without frequent maintenance or lubrication (grease-free operation up to 200 r/min).
High Chemical and Thermal Resistance
The use of premium materials enhances the seal’s durability.
Modular and Customizable Design
The HWS Ceramic Mechanical Seal offers a modular configuration that supports various glass connectors, including conical joints, flat flanges, and screw threads. Optional features include a hose clip for nitrogen overlay, direct-connected stirrer motors, and stainless-steel flanges for secure cover connections.
