DAB.MOTOR 4OL - 4" submersible motors
The DAB.MOTOR 4OL series includes 4-inch submersible motors designed for deep well and industrial pumping systems. These motors are built with a two-pole asynchronous design and rewound for custom applications. Constructed with AISI 304 stainless steel components, they offer durability in corrosive environments. The rotor is supported by plain radial bearings, with axial loads managed by a plain heel bearing, all lubricated and cooled using FDA-approved oil. The stator is sealed in an AISI 304L stainless steel housing, and the winding connections are routed through a flat four-core cable for secure power integration.
How to choose
- Verify the required voltage (1x230V or 3x400V) to match the electrical system of the installation.
- Select the appropriate power rating (e.g., 1.1kW) based on the pump’s hydraulic requirements and flow rate.
- Ensure compatibility with NEMA 4" flange connections for secure mounting to the pump body.
- Confirm the motor is suitable for the intended installation orientation—vertical or horizontal (0.5 HP to 10 HP range).
- Consider the need for a control box for single-phase motors, which includes a start capacitor and overload protection.
Frequently asked questions
Can the motor be installed horizontally?
Yes, the DAB.MOTOR 4OL supports horizontal installation for power ratings between 0.5 HP and 10 HP.
What type of lubrication is used for the bearings?
The radial and heel bearings are lubricated and cooled using FDA-approved oil filling.
What protection rating is provided?
The motors are rated IP68, allowing full submersion up to a maximum depth of 250 m.
