PDF datasheet mirror for 7045 (Flygt Pumps). Verify with OEM before design.
Summary
Product identification
Flygt propeller pumps are designed for cost-effective transport of large volumes of water at low heads. Specific models mentioned include 7045, 7050, 7055, 7061, 7065, 7076, 7081, 7101, 7105, 7121, and 7125.
Operating limits
- Ratings: Up to 578 kW or 775 hp
- Flow: Up to 7200 l/s or 120,000 USgpm
- Stator windings: Rated at 180°C (355°F)
- Starts per hour: Up to 15
- Bearing service life: Minimum 100,000 hours
Feed water
Flygt propeller pumps are designed to operate submerged in the pumped liquid. Typical applications include:
- Storm water
- WWTP Effluent
- Water intakes
- Flood control
- Amusement park attractions
- Surf riders
Electrical
- Power ratings: Up to 578 kW or 775 hp
- Stator windings: Rated at 180°C (355°F) with Class H insulating resin.
- Sensors:
- Thermal sensors in stator windings prevent overheating.
- Analogue temperature sensor monitors the lower bearing.
- Leakage sensors in the stator housing and junction box.
- Compliance: Tested and approved in accordance with national and international standards, including IEC 34-1 and CSA. Explosion-proof versions are approved by Factory Mutual, European Standard, and IEC.
- Monitoring and Control:
- Flygt MiniCAS: Supervision relay for stator temperature and leakage sensors for smaller Flygt propeller pumps.
- Flygt MAS 711: Protective monitoring system for medium and large capacity Flygt propeller pumps.
Mechanical / hydraulic
- Flow: Up to 7200 l/s or 120,000 USgpm
- Design:
- Slim profile for a considerably smaller pump station footprint.
- Submersible design, requiring no fastening bolts for installation.
- Patented N-technology for self-cleaning capabilities, featuring backswept propeller blade design, a relief groove in the wear ring, and guide vanes.
- Modular design.
- Sealing:
- Active Seal™ system: A patented zero-leakage double-seal system that actively prevents liquid from entering the motor cavity. The unique inner seal has laser-cut spiral grooves that act as a micro-pump.
- Two sets of mechanical shaft seals work independently for double security.
- Cable entry provides sealing and strain relief.
- Bearings: Durable bearings provide a minimum service life of 100,000 hours.
