GW 28 Imperial Size Seal for Haigh® Pump & Macerator Equipment
This robust mechanical seal is specifically designed to withstand the demanding conditions of solid-laden and high-viscosity media. It is particularly well-suited for:
• Municipal wastewater and sewage treatment plants
• Sludge transfer and maceration systems
• Industrial effluent handling with abrasive particles
• Pumping applications involving fibrous materials
Product Detail
+
The GW 28 is a mechanical seal engineered for severe-duty applications in Haigh® pumps and macerator equipment. Its design incorporates premium Silicon Carbide (SiC) sealing faces, a material known for exceptional hardness (Knoop hardness 2500 kg/mm²) and superior wear resistance, making it ideal for handling abrasive media common in wastewater processing.
The seal's robust construction and balanced design provide reliable performance under the shock loads, viscosity changes, and solid contents encountered in maceration and sludge transfer duties. Precision-engineered spring loading maintains optimal face contact pressure even under shaft deflection and vibration conditions. As a direct OEM replacement, it ensures dimensional interchangeability while offering enhanced durability for extended maintenance intervals in challenging environments.
