Условия применения
Liquid temperature:
— up to a 35 °C for 4” motors
— up to 30 °C for 6” motors.
Maximum amount of sand in the water:
— 150 g/m3 for 4SDP and 300 g/m3 for 6SDP.
— 300 g/m3 high percentage of solids and sand.
Continuous duty
Двигатель
2-pole induction motor, 50 Hz (n ≈ 2900 rpm).
Sized for connection to the pumps according to NEMA Standards.
Standard voltages:
single-phase — single-phase 230 V up to 2,2 kW for 4” motors.
three-phase — three-phase 230 V; 400 V, for 4” motors.
— three-phase 400 V; 400/690 V, for 6” motors.
Voltage tolerance : +6% / -10%.
In order to limit both current and torque at each starting, for rated motor powers equal to or higher than 7.5 kW, one of the following types of starting is necessary: star/delta, soft starter, stator impedance or autotransformer.
Insulation class F for 4” motors, class E for 6” motors.
Protection IP 68.
Continuous duty.
4” motor suitable operation with frequency converter (4” singlephase excluded).
6” motor suitable operation with frequency converter (with suitable filter dv/dt).
