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 into the motor provides a soft start without water hammer and a wide supply voltage tolerance range, while the drive's smaller dimensions make it easier to install in narrow boreholes.
Who it's for
-
Single-family homeowners – The compact design fits narrow wells, while the wide supply voltage range (160–250 V) improves 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 – Soft start reduces mechanical and electrical loads when the pump is switched on frequently.
-
Installers – Smaller motor dimensions with the same hydraulic performance reduce borehole drilling and installation costs.
Applications
The 3" IBQ series is designed to draw raw water from boreholes and open water reservoirs for single-family homes, farms, garden and orchard irrigation, land drainage, and supplying raw water to water supply and industrial systems before treatment. The pump does not treat water; if using it for other purposes, we recommend ensuring appropriate water treatment.
The pumps run on single-phase power across a wide voltage 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, as required by the motor's soft-start characteristics.
Features of the 3" IBQ Series
IBO 3" IBQ series pumps are equipped with a high-speed motor (6000 rpm) that uses permanent magnets, and an inverter. The inverter does not adjust the pump's output according to water demand; its purpose is to increase and maintain the motor's high speed, allowing a smaller motor to be used with the same hydraulic performance as a conventional pump.
The inverter provides a smooth, several-second startup without a sudden increase in current draw or water hammer in the system. It also monitors the motor's current draw and switches 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 pump has a maximum diameter of 78 mm, allowing it to be installed in standard 3-inch drilled wells. Before purchasing, it's worth measuring the actual borehole diameter to avoid installation problems.
What makes the 3" IBQ pump stand out?
The pump uses a high-speed motor (6000 rpm) with permanent magnets and a frequency inverter, allowing it to be smaller than a conventional motor while delivering the same hydraulic performance. 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 power consumption.
Does the 3" IBQ pump require a special pressure tank?
Due to its gentle, several-second startup, the pump should be used with a pressure tank with a capacity of at least 80 l. A tank that is too small may cause the pump to switch on too often.
How do I choose a 3" IBQ pump model to suit my needs?
The model you choose depends on the well depth and the amount of water needed at one time. The series includes models with different heads and flow rates, from modest household needs to larger agricultural and industrial installations. We encourage you to contact our technical department if you have any questions.
Where can I buy an IBO 3" IBQ submersible pump?
Dambat does not sell directly. 3" IBQ series pumps are available from sales partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 3" IBQ pump?
IBO - 24 months (2 years) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
