Submersible sewage pump: FA 15.99D
Motor type: FKT 50.1-4/57G
Type of impeller: Three-channel
Type of installation: Dry sump installation

VERSION
Submersible sewage pump as a submersible, single-stage monobloc unit in stationary, vertical installation, for pumping untreated sewage that does not attack the pumps either chemically or mechanically. Pump with radially arranged discharge port and axial pump inlet. Unit structure is easy to service due to split motor and pump housing unit.
The pumping values must be guaranteed in accordance with ISO 9906 Annex A.
For the pump type FA 15.99D, the version type also depends on the motor!
Please select a motor in the drop-down menu on the right and read the relevant description:

Submersible motor in pressure-resistant design with internal, sealed active
circulation cooling between motor housing and cooling shroud. The heat is dissipated via the heat exchanger. Motor chamber dry.
Sealing of the motor at the shaft by two wear-resistant mechanical shaft seals independent of the direction of
rotation entirely made of silicon-carbide. Both seals are cooled and lubricated by water-glycol.
Motor chamber and terminal chamber are monitored by a humidity sensor.
The terminal chamber is equipped with a terminal board.
Both lower ball bearings are filled with high-quality grease and can be subsequently lubricated.
The upper ball bearing is maintenance-free and filled with high-quality grease.
Leakage chamber with float switch for the control of second mechanical seal.
Protection of the motor winding by thermistors installed.
The cable trumpet is longitudinally tight.
All casing parts are made of cast iron, cooling shroud made of steel, connection elements made of stainless steel, motor shaft made of
high-quality heat-treated steel. The motor is suitable for continuous operation (S1) under full load in immerged and completely emerged condition.
