3" IBQ 2-11 – submersible pump
The IBO 3" IBQ submersible pump is a multistage design with a high-speed motor, intended for drawing and pumping raw water in single-family homes and farms, as well as for irrigation, drainage, and industrial applications. The inverter integrated with the motor provides a soft start without water hammer and a wide range of tolerated supply voltage, while the drive’s smaller dimensions facilitate installation in narrow boreholes.
Who it is for
-
Owners of single-family homes – the compact design fits narrow wells, while the wide supply voltage range (160–250 V) increases resistance to fluctuations in the power grid.
-
Farms and horticultural operations – higher-capacity models supply irrigation systems and drip lines without the need for a larger motor.
-
Industrial and drainage systems – the soft start reduces mechanical and electrical loads during frequent pump starts.
-
Installers – the motor’s smaller dimensions, while maintaining the same hydraulic parameters, reduce borehole and installation costs.
Applications
The 3" IBQ series is designed for drawing raw water from boreholes and open water tanks for single-family homes, farms, garden and orchard irrigation, site drainage, and supplying water-supply and industrial systems with raw water before treatment. The pump is not a water-treatment device – when using it for other purposes, we recommend ensuring appropriate water preparation.
The pumps operate on single-phase power across a wide range of 160–250 V, with a maximum pumped-liquid temperature of 35°C. The 3" IBQ 230 V submersible pump works with a pressure tank with a capacity of at least 80 l, which results from the motor’s soft-start characteristics.
Features of the 3" IBQ series
The IBO 3" IBQ series pumps are equipped with a high-speed motor (6000 rpm) using permanent magnets and an inverter. The inverter does not regulate pump capacity according to water demand – its purpose is to increase and maintain the motor’s high speed, which allows a smaller motor to be used with the same hydraulic parameters as a traditional pump.
The inverter provides a gentle, several-second start without a sudden increase in current draw or water hammer in the system, and it also monitors the motor’s current draw, switching off the pump if dry running is detected. The body, housing, shaft, and rotor are made of AISI 304 stainless steel, while the impeller and diffuser are made of PPO polymer.

Frequently asked questions (FAQ) – IBO 3" IBQ submersible pump
What type of well is the 3" IBQ submersible pump suitable for?
The maximum pump diameter is 78 mm, allowing installation in typical 3-inch drilled wells. Before purchasing, it is worth measuring the actual borehole diameter to avoid installation problems.
What distinguishes the 3" IBQ pump?
The pump uses a high-speed motor (6000 rpm) with permanent magnets and an inverter, allowing it to have smaller dimensions than a traditional motor while maintaining the same hydraulic parameters. The inverter also provides a soft start without water hammer, a wide supply voltage range (160–250 V), and built-in dry-run protection based on monitoring current draw.
Does the 3" IBQ pump require a special pressure tank?
Due to its gentle, several-second start, the pump should operate with a pressure tank with a capacity of at least 80 l – a tank that is too small may cause the pump to start too frequently.
How do I choose the right 3" IBQ pump model for my needs?
The choice of model depends on the well depth and the amount of water required at the same time – the series includes variants with different delivery heads and capacities, from modest domestic needs to larger agricultural and industrial systems. If in doubt, we encourage you to contact the technical department.
Where can I buy the IBO 3" IBQ submersible pump?
Dambat does not sell directly. 3" IBQ series pumps are available from commercial partners, installation wholesalers, and authorized online distributors.
What warranty terms apply to the 3" IBQ pump?
IBO – 24-month (2-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
