Product Overview
Operating at 485 rpm with flow capacity of 21000 L/min and maximum head of 7.6 m, the Grundfos S3.120.300.150.12.62F.C.449.G.N.D.513GPA 12-pole submersible sewage pump handles wastewater, process water and unscreened raw sewage where very high flow rates at low heads are required. The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m.
A 15 kW motor (P2) at 485 rpm from a 415 V three-phase supply draws 36 A with 84% efficiency at full load and 85% at 3/4 load. The 449 mm impeller delivers the specified performance, with DN300 outlet and DN120 inlet connections carrying a PN10 pressure rating.
Hydraulic performance is achieved through a 3-channel ductile iron impeller with 120 mm free passage, with the impeller diameter and triple-channel configuration matched to the F lifting height class requirements. The impeller geometry determines the head and flow characteristics for this Range 62 model.
IP68 enclosure and Class F insulation are provided by the cast iron housing, with primary silicon carbide and secondary silicon carbide-carbon shaft seals protecting the motor compartment. Integrated moisture sensors are fitted as standard, with 15 m S1BN8-F cable and Star/Delta starting.
FEATURES
- 12-Pole Motor Design: The 12-pole motor operates at 485 rpm, providing low-speed operation suitable for high-volume transfer applications where reduced hydraulic loading is beneficial.
- 3-Channel Ductile Iron Impeller: The triple-channel impeller design provides stable hydraulic performance across the operating range while maintaining efficient solids handling capability for municipal wastewater applications.
- 120 mm Free Passage: The internal clearance through the impeller and volute allows solids and unscreened sewage particulates to pass without blocking the hydraulic flow path during operation.
- DN300 / DN120 Connection: The outlet connection is sized at DN300 with a PN10 pressure rating, while the inlet connection is DN120, matching the hydraulic design requirements of this configuration.
- Variant C Cooling Jacket: The integrated cooling jacket surrounds the motor stator to dissipate heat during continuous submerged operation, maintaining stable motor temperatures in wet well installations.
- IP68 Enclosure Protection: The motor housing is fully sealed against permanent submersion, with the IP68 rating confirming suitability for continuous operation at depths up to 20 m.
- Silicon Carbide Shaft Seals: The primary shaft seal uses silicon carbide faces while the secondary seal employs a silicon carbide-carbon combination, providing two-stage protection against liquid ingress into the motor compartment.
- Integrated Moisture Sensors: Sensors are fitted within the motor housing to detect the presence of moisture, providing early indication of potential seal degradation or liquid ingress during service.

What metallurgy and internal hydraulic clearance ensure anti-corrosion operation in this pump?
Manufacturing standards for the S3.120.300.150.12.62F.C.449 specify Cast iron housing and wetted components paired with a specialized channel impeller providing spherical solid passage up to 120 mm.
What electrical supply voltage and motor power current are engineered into this sewage pump?
Functioning on three-phase electrical distribution, the Grundfos S3.120.300.150.12.62F.C.449 employs a motor rated at 15 kW running on 415 V, 50 Hz, three-phase at 36 A.
What maximum operational submergence depth and fluid temperature are engineered into this pump?
Submergence tolerance certified on the S3-120-300-150-12-62F-C-449 permits installation depths extending up to approximately 20 m in liquid temperatures up to 40°C.
Through its robust hydraulic design, what peak vertical elevation head does this pump deliver?
Operating against vertical static pressure, the S3 120 300 150 12 62F C 449 produces a maximum dynamic head of approximately 7.6 m.
Under full fluid loading, what maximum delivery flow does this wastewater pump maintain?
Delivering high fluid displacement, the S3.120.300.150.12.62F.C.449.G.N.D.513GPA produces a maximum delivery flow volume of approximately 21000 L/Min through a DN 300 (standard flanged connection).
