DAB Drenag 1000-1200: Construction Site Pumps for Sandy Water

DAB Drenag 1000 - 1200: The Stainless Steel Pump for Sandy Water

Power and Resistance for Construction Sites and Severe Flooding

The DAB Drenag series (models 1000 and 1200) represents the professional standard for draining clear or slightly dirty water containing sand and abrasive debris . Built entirely in AISI 304 stainless steel, it is designed to withstand the harsh conditions of construction sites, excavations, and major domestic flooding.

  • Anti-Abrasion: Rubberized shaving disc to resist sand wear.
  • High Performance: Head up to 17 metres (Drenag 1200) for emptying deep underground garages.
  • Solids Passage: Handles debris up to 10mm in diameter.

Do you need to empty a construction site or a room full of liquid sludge?

Normal plastic pumps burn as soon as they suck up a bit of sand or gravel. The DAB Drenag was designed for this very purpose: the pump body, impeller, and suction screen are made of cast stainless steel to withstand impact or abrasion.

It's the ultimate choice for those seeking speed: with a flow rate exceeding 400 litres per minute, it empties a garage ramp or flooded excavation in just a few minutes, allowing you to get back to work right away.

⚙️ Version Guide (Don't mess up your code!)

For each model (1000 or 1200), there are three configurations. Choose the one that's right for your job:

1. MA Version (Automatic Single Phase)
• Has the wire float included.
• Turns on and off automatically. Ideal for fixed installations in wells or for domestic emergencies.
2. M-NA Version (Single-Phase Non-Automatic)
WITHOUT Float . It turns on as soon as you plug it in.
• Preferred by bricklayers for draining excavations "to the last drop" under manual supervision.
3. T-NA Version (Three-Phase)
• For construction sites with 400V industrial power supply. Without float switch.

Total Reliability

The motor is cooled directly by the pumped water, allowing the pump to operate even when partially submerged (as long as the grid is covered). The rubberized handle ensures a firm grip even with wet work gloves.

Frequently Asked Questions about DAB Drenag

What is the difference between Drenag 1000 and 1200?

Change the power and delivery head (height thrust). The Drenag 1000 reaches about 15 meters in height. The Drenag 1200 is more powerful (1.2 kW) and reaches 17 meters. If you have a very high drop or long pipes, choose the 1200.

Can I use it for the sewer (toilet)?

No. Although powerful, the Drenag has a screen that traps solids larger than 10mm. For wastewater with large solids (stool, paper), the DAB FEKA series is needed, which has wider passages.

Which exhaust pipe do you need?

The delivery is 1" 1/2 (one and a half inches) . We strongly recommend using a spiral or rigid tube of this diameter (or larger) to avoid restricting the pump's performance.
