DAB 4GG 3.0 kW 4" submersible motor, 3 × 400 V – water-filled, two-pole (DAB.MOTOR 4GG)

Product detailed description

The DAB 4GG 3.0 kW T (code 60122758) is a 4" two-pole asynchronous submersible motor for a 3 × 400 V three-phase supply. It is coupled to the pump end of a submersible pump via the standard NEMA 4" flange – for example DAB S4 pumps – and drives it in the borehole or well.

Construction

All parts in contact with the pumped water are AISI 304 stainless steel; the upper and lower end covers are Teflon-coated cast iron with stainless-steel cladding. The stainless shaft runs in graphite sleeve bearings, and axial forces are carried by a self-centring stainless Kingsbury thrust bearing. The bearings are cooled and lubricated by a water–glycol fill, and the stator is enclosed in a watertight stainless-steel housing. From 3.0 kW the rotor has a copper cage. The motor is supplied with a detachable four-core cable (4 × 1.5 mm², 2.7 m), which makes installation and removal easier.

Data for 3.0 kW / 3 × 400 V

• rated current 8.3 A, starting current 38 A
• max. power input P1 4050 W, speed 2840 rpm
• permissible axial load 6000 N
• length 544 mm, weight 19.7 kg
• IP68 protection, class F insulation, submersion up to 300 m, no more than 20 starts per hour

The motor can run vertically or horizontally, and also on a frequency converter between 30 and 50 Hz. The water may be 0 to +35 °C if it flows past the motor at no less than 0.2 m/s; otherwise a cooling sleeve is needed. Protection of the three-phase motor is provided by the user in the electrical installation; connection must be carried out by a qualified person.

Technical data

Frequently asked questions

Which pumps does the 4GG motor go with?
4" submersible pumps with a NEMA 4" flange, for example DAB S4 pump ends. The pump power must not exceed the motor’s 3.0 kW.

How does the water-filled 4GG differ from the oil-filled 4OL?
The 4GG is filled with a water–glycol mixture and has sleeve bearings; the 4OL has an oil fill and rolling bearings. The 4GG allows submersion to 300 m, the 4OL to 250 m.

Is motor protection included?
No. Overload protection of the three-phase motor is provided by the user in the electrical installation, for example with a suitable control panel. The motor comes with a detachable four-core cable 2.7 m long.
