Submersible sewage pump: FA 05.23RFW
Motor type: T 12-2/11GRF
Type of impeller: Vortex impeller
Type of installation: Suspension device
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 05.23RFW, 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. The sealing chamber is
filled with medical white oil. 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
with intermediate separation chamber. Both seals are cooled and lubricated by medical white oil. Both closed ball bearings are
maintenance-free and filled with high-quality grease. Power supply cable and control cable with longitudinally tight cable trumpet,
cores embedded in casting resin and soldered strands as additional
protection against penetrating humidity by capillary action.
Moisture probe by means of a pencil electrode as protection against penetrating humidity can be installed at a later time.
All casing parts are completely of stainless steel 1.4581. Shaft and connecting elements are of stainless steel.
