DAB Micra HS: 3" Constant Pressure Submersible Pump

DAB Micra HS: 3-Inch Constant Pressure Technology

High Performance in Ultra-Compact Size

The DAB Micra HS (High Speed) series represents the cutting edge of submersible pumps for boreholes. With a diameter of just 3 inches , it is designed to operate in extremely narrow or partially obstructed wells, ensuring constant pressure thanks to the system's integrated frequency converter (inverter).

  • ✅ 3" Diameter: Ideal for wells where standard 4" pumps cannot access.
  • ✅ HS Inverter: Modulates the motor speed to keep the pressure always constant.
  • ✅ Energy Saving: Consumes only the energy strictly necessary for water demand.
  • ✅ Integrated Protections: Safety against dry running, overload and voltage surges.

Why choose Micra HS for your well?

Older artesian wells often have restrictions or 3-inch jackets that make it impossible to use standard pumps. The DAB Micra HS solves this problem without sacrificing power. Thanks to its high-speed motor, this small pump can push water to great heights, offering performance comparable to much larger machines.

But the real advantage is comfort . The variable frequency system eliminates annoying pressure fluctuations: whether you're using just one sprinkler or the whole family is showering, the water flow will always remain the same, without drops.

💎 The Active Driver Plus System

The Micra HS is usually paired with DAB's Active Driver Plus inverter. This electronic "brain" allows you to:

  • Extend pump life: Thanks to "soft start" (slow starts), water hammer is eliminated.
  • Reduce your bill: The engine does not always run at maximum, but adapts to the actual consumption.
  • Eliminate large expansion vessels: A small 2-liter tank is enough to manage the entire system.

Noble Materials and Reliability

Despite its compact size, there's no compromise on quality. The pump body, impellers, and shaft are made of AISI 304 stainless steel to ensure complete corrosion resistance. It's the perfect choice for those seeking a modern, invisible, and incredibly efficient pressurization system.

Frequently Asked Questions about the DAB Micra HS

What does "High Speed" mean?

This means the motor can rotate up to 6,300 rpm (compared to 2,800 rpm for standard pumps). This allows for a lot of pressure to be generated with very small impellers, keeping the pump diameter within 3 inches.

What is the exact diameter of the well required?

The Micra HS has a diameter of 74mm. It can be installed in wells with a minimum internal diameter of 3 inches (approximately 76-80mm).

Can I use it without the inverter?

Micra HS pumps are designed specifically to work with their inverter module. Using them without the dedicated electronic control is not possible as the motor requires a variable power frequency.
