Good service access to pump suction side with unique telescopic opening
Flygt Z lifting equipment simplifies service
Optional rails and service cart
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)
INSTALLATION COMPONENTS
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.
Dry Installation (Z)
Horizontal, permanent, dry pump installation. The submersible pump is installed in a dry pit, with flange connection to suction and discharge piping.
