Description
4" IBQ 20-4 – submersible pump
The IBO 4" IBQ 20-4 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 water intakes, before the treatment process. It is driven by a synchronous permanent-magnet (PM) motor operating with a dedicated variable frequency drive (VFD), running at speeds of up to 5000 rpm. The most powerful configuration combines high flow capacity with high head, making it suitable for deep water intakes and extensive installations.
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 hydrophore system or water treatment station.
- Farms and horticultural operations – a capacity of up to 500.0 l/min enables the pump to supply irrigation systems, drip lines and buffer tanks.
- Industrial and construction installations – continuous-duty operation, IP68 protection rating and AISI 304 stainless steel construction make the pump suitable for demanding conditions.
- Installers – the PM motor with inverter enables high hydraulic performance in a compact 4" borehole installation.
Applications
The 4" IBQ 20-4 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 operation monitoring are essential.
The submersible pump is not a water treatment device and does not constitute confirmation 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 appropriate treatment and water quality testing at the point of collection.
The maximum temperature of the pumped liquid is 35°C. Pumped raw / untreated water must not contain mechanical impurities exceeding the permissible parameters for this model.
Features of the 4" IBQ IVR series
As the 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 demand; 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 environmentally friendly oil.

Frequently asked questions (FAQ) – IBO 4" IBQ 20-4 submersible pump
What type of well is the 4" IBQ 20-4 pump suitable for?
The pump’s external diameter is 98 mm and its length is 1040 mm, allowing installation in typical 4-inch drilled wells. The maximum immersion depth is 100 m. Before purchasing, it is worth measuring the actual borehole diameter and checking the water table level.
What distinguishes the 4" IBQ IVR series?
These pumps use a synchronous permanent-magnet (PM) motor operating 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 20-4 model?
The pump is powered by three-phase voltage, 3~400 V, 50 Hz, with a power rating of 5.5 kW and a rated current of 12.8 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 20-4 pump supply drinking water?
No. The pump operates in the raw/untreated water zone—it 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 consumption. When using water for drinking or domestic purposes, appropriate treatment and water quality testing 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 20-4 model is the most powerful of the three: flow rate up to 500 l/min at a head of up to 138 m and a power rating of 5.5 kW. Choose it when the water intake is deep and a high flow rate is also required. For lower flow requirements, the 12-4 model will be sufficient, while for a shallower intake, choose the 20-3 model. If in doubt, we encourage you to contact the technical department.
Where can I buy the IBO 4" IBQ 20-4 submersible pump?
Dambat does not sell directly. 4" IBQ IVR series pumps are available from commercial partners, installation wholesalers, and authorized online distributors.
What warranty terms apply to the 4" IBQ 20-4 pump?
IBO – 24 months (2 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
