The SG-805 Series™ sealless external gear pump is designed for applications where shaft seal leakage is unacceptable. This mag drive pump offers a hermetically sealed solution using magnet drive technology which eliminates traditional shaft seals and associated issues like wear, leakage, and air infiltration. It can handle flows up to 11.2 GPM (2.54 m³/h).
Features & Benefits
- Leak-Free Operation: Hermetically sealed design eliminates shaft seals, preventing leakage and air infiltration—ideal for hard-to-seal or hazardous liquids.
- Low Maintenance: Magnetic drive system reduces wear and eliminates seal-related maintenance, improving reliability and uptime.
- Enhanced Cooling & Flow: Hollow shaft enables internal fluid circulation for magnet cooling and product movement, preventing stagnation and ensuring consistent performance.
