SX 2-3

No. These are different limits of the curve. Read flow at your actual total head on the SX 2 curve.

Supply the internal sump dimensions and intended switching levels. Leave room for the float to move without catching on the wall or pipe.

Flygt SX 2-3 drains water from basements, garages and rainwater tanks. At 50 Hz the SX 2 and SX 3 have distinct curves. Add discharge-line losses to the lift from the sump and compare the resulting duty; a model’s maximum flow and maximum head are not delivered simultaneously. Example applications: Emergency drainage of basements and garages; Water transfer or garden irrigation from rainwater tanks.

SX 2 limits (50 Hz): 135 L/min; 7 m (separate limits). Verify against the complete model code, frequency and operating conditions.

SX 3 limits (50 Hz): 225 L/min; 11 m (separate limits). Verify against the complete model code, frequency and operating conditions.

Maximum immersion: 5 m. Verify against the complete model code, frequency and operating conditions.

SX 2 is single-phase; SX 3 supply and float options depend on the version. Stainless steel outer casing; pumped water cools the motor. Assess these features with flow, head, fluid and installation conditions.

Establish solids size, fibrous content, sump geometry and minimum liquid level. Drainage and sewage pumps have different application limits.

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.

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.

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.
