Submersible sewage pump: FA 10.44W
Motor type: T 20.1-6/32K
Type of impeller: Vortex impeller
Type of installation: Suspension device 1
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 10.44W, 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 double mechanical shaft seal in EMU block design, as well as separate
sealing chamber filled with medical white oil and additional leakage chamber with float control. Motor chamber dry. Sealing
of the motor at the shaft by a double, wear-resistant mechanical shaft seal independent of the direction of rotation entirely
made of silicon-carbide as closed unit in sealing cartridge of stainless steel and additional shaft sealing ring. Both seals in the
sealing cartridge are cooled and lubricated by medical white oil or water/glycol on customer’s request. The motor chamber is
equipped with connecting terminals. Protection of the motor winding by thermistors installed. Both closed ball bearings are
maintenance-free and filled with high-quality grease. All casing parts are of cast iron, shaft and connecting elements are of
stainless steel. The motor is suitable for intermittent operation (S2) under full load in emerged condition.
