OPERATION OF DRY INSTALLED SUBMERSIBLE PUMPS
Flygt submersible pumps offer operational advantages in pump stations with dry installed pumps:
- Leakage free operation. There is no external shaft seal that can leak wastewater into the pump room.
- Flood-proof motor. If the pump room is flooded, the submersible pump keeps on working.
- Motors bigger than 10kW feature built-in cooling that minimizes the power consumption of ventilation fans. Cooling is independent of the ambient air temperature.
Service is simplified with:
- The patented telescopic service hatch, allowing good access to the pump suction side (Flygt pumps 3085–3315)
- Drainage valve in the pump volute (Flygt pumps 3085–3315)
- Lifting equipment designed for handling of the motor and impeller
- Service cart and rails for easy access to the drive unit and impeller (Flygt pumps 3153–3315)
Flygt pumps NT 3085–3315 have a stand with the patented telescopic service opening. Options include:
- Drainage valve
- Service lifting device
- Service cart and rails (10–100 kW, pumps 3085–3315)
Large Flygt pumps CT and NT 3231–3800 come with a sturdy steel stand. An optional service lifting device is available for the motor and impeller.
