DAB Micra: 3-Inch Submersible Pumps for Narrow Wells

DAB Micra: 3" Submersible Pumps for Small Diameter Wells

The professional solution where space is limited

The DAB Micra series is the ideal choice for lifting clean water from drilled wells with a minimum diameter of 3 inches (DN 80). Designed for domestic, irrigation, and small civil applications, this pump combines an ultra-slim design with the robust construction of stainless steel, ensuring excellent performance even in space-constrained conditions.

  • ✅ Diameter 74mm: Designed specifically for narrow wells or deformed liners.
  • ✅ Stainless Steel Construction: Pump body, shaft and joint made of AISI 304 stainless steel for maximum durability.
  • ✅ Easy Maintenance: Pump and motor can be separated, making any technical interventions easier.
  • ✅ DAB Quality: Reliable and high-performance asynchronous submersible motor.

Why choose a 3" pump like the Micra?

Often, in older artesian wells or those drilled using light drilling techniques, the internal space does not allow for the insertion of a standard 4-inch pump. Forcing a larger pump into the well risks it getting stuck or not being cooled properly. The DAB Micra , with its mere 74mm footprint, slides easily into the well, ensuring a constant flow of water without mechanical risks.

It is the ideal pump for those looking for a home pressurization system or an efficient sprinkler irrigation system, without having to face the high costs of a larger drilling or complex inverter systems.

🛡️ Miniature toughness

Despite its small size, the Micra series makes no compromises on materials:

  • Impellers and Diffusers: Made of high-resistance technopolymer to handle water with small impurities.
  • Motor Protection: In single-phase versions, thermal protection is included in the motor to prevent damage from overheating.
  • Non-Return Valve: Integrated into the pump head to protect impellers and diffusers from water hammer.

Tips for a perfect installation

To ensure maximum longevity for your DAB Micra pump, we recommend using a suitable electrical protection panel. Since the space between the pump and the well wall is minimal, it is essential that the water is clean and free of excessive sand. Using an electrical cable of the correct gauge will prevent voltage drops that could strain the asynchronous motor.

Frequently Asked Questions about DAB Micra

Is the Control Box (capacitor) included?

It depends on the specific model. Many single-phase versions of the Micra require an external capacitor, which is usually housed in the electrical control panel. Always check the technical data sheet to see if the panel is included or if it must be purchased separately.

What is the difference between Micra and Micra HS?

The standard Micra operates at a fixed speed (50Hz), is simpler and more economical. The Micra HS operates at a high speed with an inverter that regulates constant pressure. If you have a simple system or a limited budget, the standard Micra is the best choice.

How deep can it go?

The Micra series allows for a maximum immersion below water level of up to 70 metres, with total heads that can exceed 90 metres depending on the number of impellers in the chosen model.
