Key Features
- Heavy-duty, high-efficiency, air filled, Class H insulated motor – rated for 356°F with a 1.15 service factor dissipates heat easily; thermal protection in each phase of windings protects; operates cooler with higher efficiencies; longer service life with lower operating costs
- Watertight cable entry system – protects against moisture and capillary action; reduces maintenance costs
- Self-cooling jacket – eliminates the need for external pumping devices or special heat transfer fluids; offers simplicity and high reliability by effectively dissipating heat in dry pit applications only
- 60,000 hour single and double row thrust bearings – long dependable operation, lowers maintenance costs
- High-efficiency impellers – ability to pass large solids with high outputs prevent clogging and handles stringy material better, impellers are optimized for hydraulic coverage lowering operating costs
- Double mechanical seals – operate in an oil bath providing longer service life and lower maintenance costs
- Stainless steel shaft – high tensile strength and corrosion resistance
- Replaceable wear components – maintain working clearances while reducing casing and volute costs
