DAB S4 AMEIRA: The Evolution of the 4-Inch Submersible Pump

Superior Efficiency and Maximum Sand Resistance

The DAB S4 AMEIRA series is the new line of multistage submersible pumps designed for wells 4 inches or larger. An evolution of the historic S4 series, the Ameira improves hydraulic efficiency and construction robustness, confirming itself as the ideal choice for domestic water supply, agricultural irrigation, and professional pressure booster sets.

  • ✅ Anti-Sand: Floating impellers that allow the passage of sand up to 150 g/m³.
  • ✅ AISI 304 Stainless Steel: Support, head and external jacket in stainless steel for eternal durability.
  • ✅ NEMA Standard: Universal fit for 4" submersible motors.
  • ✅ Certified Efficiency: Compliant with the ErP directive with MEI indices higher than the market standard.

Why upgrade to the new AMEIRA S4 series?

In an artesian well, working conditions are unseen and demanding. The DAB S4 AMEIRA has been redesigned to overcome the limitations of traditional pumps. Thanks to the new technopolymer materials of the impellers and the geometry of the diffusers, this pump drastically reduces friction and mechanical wear, ensuring a constant water flow rate even after years of use in the presence of sandy sediments.

It's the "standard" pump for installers who don't want to return to the job site due to blockages or pressure drops. If you're looking for a solution that combines DAB tradition with technological innovation, the Ameira series is your new go-to.

⚙️ Technical Features of Relief

Every detail of the S4 Ameira is designed for maximum reliability:

  • Non-Return Valve: Integrated into the head to protect the impellers from water hammer.
  • Suction Filter: Made of stainless steel to block larger debris.
  • Cable Protection: Stainless steel cable cover to prevent damage during descent into the well.
  • Drinkable certification: Materials suitable for contact with water intended for human consumption (WRAS/ACS).

Modularity and Simplified Maintenance

The Ameira series is supplied as a hydraulic unit that can be separated from the motor. This is a huge advantage: if after years of reliable service the motor fails, you can replace only the motor while keeping your Ameira hydraulic unit, or vice versa, reducing maintenance costs and system downtime.

Frequently Asked Questions about DAB S4 AMEIRA

What does "Floating Impellers" mean?

It's a technology that allows the impellers to move axially. If a grain of sand enters the pump, the impeller "moves" slightly, allowing it to pass instead of jamming and destroying the pump. This is the secret to the Ameira series' durability.

Can I use it for a constant pressure system (Inverter)?

Absolutely. The Ameira S4 series is perfect for pairing with wall-mounted inverters like the Active Driver Plus, ensuring consistent water pressure throughout your home.

What diameter should the well be?

The pump has a maximum diameter of 99mm. It is designed for wells with a 4-inch jacket (internal diameter approximately 100-105mm).
