DAB.MOTOR 4TW - 4" submersible motors

The DAB.MOTOR 4TW series includes 4-inch submersible motors designed for integration with submersible pump systems. These motors are built for durability and performance in submerged environments, commonly used in deep well pumping, water supply systems, and industrial water management. The motors feature a compact design and are suitable for both vertical and horizontal installation, depending on the power rating (0.5 HP to 1.5 HP).

Constructed with AISI 304 stainless steel for mechanical components and a hermetically sealed stator, these motors are engineered to withstand high-pressure and corrosive conditions. The radial and heel bearings are lubricated and cooled via liquid filling, ensuring long-term reliability. A four-core flat cable allows for secure electrical connections, while the built-in start-up capacitor eliminates the need for an external start-up box.

How to choose

• Power rating: Select a motor with the appropriate kW rating (0.55kW, 0.75kW, or 1.1kW) based on the pump’s hydraulic requirements and system load.
• Electrical connection: Ensure compatibility with the system’s voltage (1x230V) and the presence of a protective conductor in the winding nodes.
• Material compatibility: The stainless steel construction makes these motors suitable for aggressive water conditions and long-term submersion.
• Installation orientation: Choose a model that supports the required installation type (vertical or horizontal) based on the pump setup and site constraints.

Frequently asked questions

Can these motors operate horizontally?
Yes, motors with power ratings from 0.5 HP to 1.5 HP are suitable for horizontal installation.

What is the maximum depth for submersion?
The motors are rated for a maximum immersion depth of 300 metres.

How is the start-up capacitor integrated?
The start-up capacitor is built into the noryl housing beneath the motor, eliminating the need for an external start-up box.
