Description
4" IBQ 20-3 – submersible pump
The IBO 4" IBQ 20-3 submersible pump belongs to the 4" IBQ IVR series of multistage centrifugal pumps designed for drawing and pumping technically clean raw / untreated water from deep intakes before the treatment process. It is driven by a permanent-magnet synchronous motor (PM) working with a dedicated variable frequency drive (VFD), operating at speeds of up to 5000 rpm. This is the highest-capacity model in the series, with a moderate head height – it is suitable wherever high flow is important and the intake is not very deep.
Who is it for?
- Owners of single-family and multi-family homes – the pump operates as part of a raw-water intake and pumping system before treatment, supplying a pressure tank system or water treatment station.
- Agricultural and horticultural farms – a capacity of up to 500.0 l/min allows the pump to supply irrigation systems, drip lines, and buffer tanks.
- Industrial and construction installations – continuous-duty operation, IP68 protection, and an AISI 304 stainless steel construction make the pump suitable for demanding conditions.
- Installers – the PM motor with an inverter provides high hydraulic performance with compact installation dimensions in a 4" borehole.
Applications
The 4" IBQ 20-3 pump is designed for drawing and pumping technically clean raw / untreated water from deep wells, retention tanks, and rivers before the treatment process. Typical applications include:
- supplying raw-water intake and pumping systems in single-family and multi-family homes,
- industrial and construction installations,
- irrigation and watering systems in agriculture,
- heat pump installations and pressure-boosting systems in the raw-water zone,
- hard-to-access locations where reliability and operational monitoring are essential.
The submersible pump is not a water treatment device and does not confirm that the water is fit for human consumption. If water from a private water intake is to be used for drinking, cooking, food preparation, or other household purposes, the user should ensure proper treatment and water quality control at the point of collection.
The maximum temperature of the pumped liquid is 35°C. The pumped raw / untreated water must not contain mechanical impurities exceeding the permissible parameters for this model.
Features of the 4" IBQ IVR series
As a manufacturer, we design the 4" IBQ IVR series to provide higher energy efficiency and more compact dimensions than traditional 4" submersible pumps at speeds of up to 5000 rpm. The inverter is not used to regulate capacity according to water consumption – its purpose is to achieve and maintain the high rotational speed of the permanent-magnet synchronous motor, allowing the same hydraulic parameters to be achieved with a smaller drive unit.
The structural components of the pump and motor are made of AISI 304 stainless steel, while the hydraulic components are made of PC and POM engineering plastics. The motor is equipped with a mechanical seal designed for operation in a deep well and lubricated with eco-friendly oil.

Frequently asked questions (FAQ) – IBO 4" IBQ 20-3 submersible pump
What type of well is the 4" IBQ 20-3 pump suitable for?
The pump has an outer diameter of 98 mm and a length of 1040 mm, allowing installation in typical 4-inch drilled wells. The maximum immersion depth is 100 m. Before purchasing, it is advisable to measure the actual borehole diameter and check the water table level.
What distinguishes the 4" IBQ IVR series?
Pumps in this series use a synchronous permanent-magnet (PM) motor that operates with a dedicated variable frequency drive (VFD) at speeds of up to 5000 rpm. This solution provides higher energy efficiency and more compact dimensions than traditional 4" submersible pumps with similar hydraulic parameters.
What power supply is required for the 4" IBQ 20-3 model?
The pump is powered by three-phase voltage, 3~400 V, 50 Hz, with a power rating of 4.0 kW and a rated current of 10.0 A. Operation is possible only with a dedicated variable frequency drive (VFD) designed for this series. The electrical installation should be carried out by a qualified electrician.
Does the 4" IBQ 20-3 pump supply drinking water?
No. The pump operates in the raw / untreated water zone and is used to draw and convey water before the treatment process. It is not a water treatment device and does not confirm that the water is suitable for drinking. When using water for consumption or household purposes, appropriate treatment and water quality monitoring at the point of collection must be ensured.
How do I choose the right model from the 4" IBQ IVR series for my needs?
The 20-3 model delivers up to 500 l/min at a head of up to 100 m. It is designed for installations with high simultaneous water demand and a moderate intake depth. If you need a higher head at the same flow rate, choose the 20-4 model; if high head at a lower flow rate is the priority, choose the 12-4 model. If in doubt, we encourage you to contact the technical department.
Where can I buy the IBO 4" IBQ 20-3 submersible pump?
Dambat does not sell directly. Pumps from the 4" IBQ IVR series are available from commercial partners, plumbing wholesalers, and authorized online distributors.
