SX 5 - 15
Open-impeller drainage with SX 5, 7, 11 and 15
Flygt SX 5-15 offers four 50 Hz curves for water containing small suspended particles. Choose between SX 5, 7, 11 and 15 by combining the flow required for the tank emptying time with the total discharge head, rather than motor power alone. The catalogue minimum liquid level of 25 mm does not mean the pump can run dry.
Final performance and suitability are verified for the selected model and duty point.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Emptying industrial water tanks · Removing dirty drainage water from plant and building sumps
Selection considerations
Establish solids size, fibrous content, sump geometry and minimum liquid level. Drainage and sewage pumps have different application limits.
Share your operating conditions with our technical team. We can assess liquid compatibility, hydraulic duty point and installation requirements together to identify the suitable variant.

Frequently asked questions
Can the SX 15 be selected for a single-phase supply?+
The 50 Hz catalogue lists the 1.5 kW SX 15 as three-phase. If only single-phase power is available, compare the duty with the single-phase models rated up to 1.1 kW.
Can SX 5-15 handle any type of dirty water?+
No. The stated limit for suspended particles is 8 mm. Larger solids, fibrous material or heavy sludge require a separate hydraulic selection.
Which applications is Flygt SX 5 - 15 used for?+
Flygt SX 5-15 offers four 50 Hz curves for water containing small suspended particles. Choose between SX 5, 7, 11 and 15 by combining the flow required for the tank emptying time with the total discharge head, rather than motor power alone. The catalogue minimum liquid level of 25 mm does not mean the pump can run dry. Example applications: Emptying industrial water tanks; Removing dirty drainage water from plant and building sumps.
What is the motor range (50 hz) specification for Flygt SX 5 - 15?+
Motor range (50 Hz): Single-phase: 0.55–1.1 kW; three-phase: 0.55–1.5 kW. Verify against the complete model code, frequency and operating conditions.
What is the maximum particle size specification for Flygt SX 5 - 15?+
Maximum particle size: 8 mm. Verify against the complete model code, frequency and operating conditions.
What is the maximum immersion specification for Flygt SX 5 - 15?+
Maximum immersion: 7 m. Verify against the complete model code, frequency and operating conditions.
Which design features influence selection of Flygt SX 5 - 15?+
Open impeller and multiple seals with an oil chamber. Single- or three-phase availability depends on the model rating. Assess these features with flow, head, fluid and installation conditions.
Which selection conditions should I check for Flygt SX 5 - 15?+
Establish solids size, fibrous content, sump geometry and minimum liquid level. Drainage and sewage pumps have different application limits.
Can Flygt SX 5 - 15 run dry?+
Dry running and dry installation are different. Even variants approved for dry installation require the specified liquid flow and motor cooling. Verify minimum level, permitted installation and thermal protection in the exact model manual.
How can I access PDF documents for Flygt SX 5 - 15?+
The Technical Documents section lists 1 document links. PDFs open on the Parla site. Check model, language, 50/60 Hz and revision; document types may vary by product.
What should I include in a quotation request for Flygt SX 5 - 15?+
