1 / 2Flygt STA — Product view
STA
Coated open impeller for drainage water carrying sand
Flygt STA is intended for flooded excavations and drainage water containing fine solids. The rubber-coated open impeller resists wear, while a labyrinth helps protect the mechanical seal from sand. Where the water level falls during pumping, do not size the unit on the fully submerged temperature rating alone.
Final performance and suitability are verified for the selected model and duty point.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Draining flooded excavations and waterlogged ground · Irrigation water transfer from rainwater storage or ditches
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 STA pump a dense sand slurry?+
The 5 mm limit describes particle size, not an allowable high concentration of solids. For sand-rich mixtures, review particle distribution and slurry density separately.
Does partial immersion change the temperature limit?+
Yes. The catalogue specifies 50 °C for full immersion and 25 °C for partial immersion. Provide the lowest operating water level.
Which applications is Flygt STA used for?+
Flygt STA is intended for flooded excavations and drainage water containing fine solids. The rubber-coated open impeller resists wear, while a labyrinth helps protect the mechanical seal from sand. Where the water level falls during pumping, do not size the unit on the fully submerged temperature rating alone. Example applications: Draining flooded excavations and waterlogged ground; Irrigation water transfer from rainwater storage or ditches.
What is the maximum immersion specification for Flygt STA?+
Maximum immersion: 5 m. Verify against the complete model code, frequency and operating conditions.
What is the maximum liquid temperature specification for Flygt STA?+
Maximum liquid temperature: Fully submerged: 50 °C; partly submerged: 25 °C. Verify against the complete model code, frequency and operating conditions.
What is the maximum particle size specification for Flygt STA?+
Maximum particle size: 5 mm. Verify against the complete model code, frequency and operating conditions.
Which design features influence selection of Flygt STA?+
Maximum suspended particle size of 5 mm. Oil-bath motor and a labyrinth limiting sand ingress at the seal. Assess these features with flow, head, fluid and installation conditions.
Which selection conditions should I check for Flygt STA?+
Establish solids size, fibrous content, sump geometry and minimum liquid level. Drainage and sewage pumps have different application limits.
Can Flygt STA 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 STA?+
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 STA?+
Share minimum, normal and maximum flow, total head, liquid and temperature, power supply, suction and installation conditions. For replacements add the nameplate, connection dimensions and measured operating values.
