Designation
Example: 6 SDX L 30 / 17 6SM
6 = Well diameter in inches
SDX = Series
L = Design made of 1.4401 EN 10088 (AISI 316)
30 = Stage identification
17 = Number of stages
6SM = Motor flange coupling

The electropumps comply with the European Regulation no. 547/2012.

Motor
2-pole induction motor, 50 Hz (n ≈ 2900 rpm).
Sized for connection to the pumps according to NEMA Standards (10” excluded).
Standard voltages:
single-phase 230 V - up to 2,2 kW for 4” motors.
three-phase         230 V; 400 V, for 4” motors.
                            400 V; 400/690 V for 6-8-10” motors.
Voltage tolerance : ± 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.
