SQF pump
Run-up time Depends on the energy source.
Start/stop No limitation to the number of starts/stops per hour.
Enclosure class IP68
Motor protection
Built into the pump.
Protection against:
• dry running by a water level electrode
• over- and undervoltage
• overload
• overtemperature.
Conductivity ≥ 70 μs/cm (micro siemens)
Sound pressure level The sound pressure level of the pump is lower than the limiting values stated in the EC Machinery Directive.
Radio noise
The SQF complies with the EMC Directive 89/336/EEC.
It is tested according to the standards EN 61000-6-2 and EN 61000-6-3.
Reset function The SQF can be reset through the CU 200 or by disconnecting the power supply for 1 minute.
Power factor PF = 1
Operation through generator Make sure that the generator output is equal to the motor input power (P1) plus 50 %, and at least (P1) plus 10 %.
Earth-leakage circuit breaker
If the pump is connected to an electric installation where an earth-leakage circuit breaker (ELCB) is used as an
additional protection, this circuit breaker must trip out when earth fault currents with DC content (pulsating DC) occur.
Installation depth
The pump must be completely submerged in the pumped liquid.
The maximum installation depth must be 500 ft below the static water table (220 PSI).
Suction strainer
Holes of the suction strainer:
• 3 SQF, 5 SQF, 6 SQF, 11 SQF, 15 SQF, 22 SQF, 30 SQF: ∅0.09 in
• 16 SQF, 25 SQF: ∅0.10 in
• 35 SQF, 45 SQF, 77 SQF: 0.16 in x 0.80 in.
Pumped liquids
pH 5 - 9
Sand content: up to 50 ppm
