4" IBQ IVR 12-6 - high-speed submersible pump with PM motor and dedicated inverter
The IBO 4" IBQ IVR series submersible pumps are multistage centrifugal devices for drawing and pumping raw water from deep sources. They are equipped with a synchronous permanent magnet (PM) motor and a dedicated inverter (VFD). As a manufacturer, we designed this series to deliver higher energy efficiency and compact dimensions at speeds of up to 5,000 rpm compared with traditional 4" submersible pumps.
Who it's for
-
Water system installers - with a design up to 60% shorter and 50% lighter than other pumps of similar capacity, clear technical specifications, and an inverter panel with quick error code diagnostics, installation and operation are significantly easier.
-
Owners of single-family homes and farms - we provide a steady supply of raw water from deep wells, with a soft start that does not overload the household electrical system.
-
Service companies and hydrogeologists - we offer easy access to documentation, Dambat technical support, and warranty and post-warranty service.
-
Agricultural, industrial, and construction facilities - our devices feature a programmable Timer function for automatic cyclic start/stop operation, making them ideal wherever the pump needs to run unattended according to a schedule.
-
Designers of heat pump and pressure-boosting systems - thanks to their compact dimensions, 4" IBQ IVR pumps are easy to integrate, even in hard-to-reach locations.
Applications
- Drawing and pumping raw water from deep wells with a minimum diameter of 4" in homes, farms, and industrial facilities.
- Supplying pressure-boosting systems in single-family and multi-family buildings.
- Irrigation systems for gardens, orchards, and agricultural crops, as well as filling and emptying retention tanks.
- Industrial and construction installations requiring continuous, automated operation with parameter monitoring.
- Compatible with heat pump installations and water retention systems in hard-to-reach locations.
The 4" IBQ IVR submersible pump runs on a three-phase 380–415 V / 50 Hz power supply with a dedicated inverter included in the set. The pump is not a water treatment device - if you use it for other purposes, we recommend ensuring appropriate water preparation.
4" IBQ IVR series features – description and technical data
IBO 4" IBQ IVR submersible pumps are multistage centrifugal units designed to draw and pump raw water from deep wells. A key feature of the series is its permanent magnet synchronous motor (PM) instead of a traditional asynchronous motor. The PM motor runs at speeds of up to 5000 rpm, resulting in higher energy efficiency, lower mechanical losses, and a much more compact design – 4" IBQ IVR pumps are up to 60% shorter and up to 50% lighter than conventional equivalents with the same hydraulic specifications.
Every pump in the 4" IBQ series is supplied with a dedicated inverter (VFD), which serves as the control and protection system. The inverter supports five operating modes: constant frequency, constant current, constant pressure, float switch, and Timer – allowing you to program a one-off operation with automatic shutdown, a delayed start, or cyclical start/stop operation according to a schedule.

Frequently asked questions (FAQ) – 4" IBQ IVR submersible pump with inverter
What is the 4" IBQ IVR submersible pump used for?
The 4" IBQ IVR submersible pump is designed to draw and pump untreated water from deep wells, storage reservoirs, and rivers for irrigation systems, pressure-boosting systems, and heat pump installations.
How does the 4" IBQ IVR pump differ from a traditional submersible pump?
The 4" IBQ IVR pump features a synchronous PM motor with a dedicated VFD inverter. Unlike traditional asynchronous pumps, it offers a soft start that eliminates water hammer, fully automatic operation, and electronic protection features not available in some designs
Who is the 4" IBQ IVR submersible pump designed for?
The 4" IBQ IVR pump is an advanced device designed for demanding systems. Thanks to its synchronous PM motor and dedicated inverter, it is ideal wherever high performance, a deep water source, and automatic operation are required: farms, industrial systems, irrigation systems, and heat pumps. Its compact design also makes it well suited to hard-to-access locations.
How do I install a 4" IBQ IVR submersible pump?
Install the pump vertically, at least 5 m above the bottom of a well with a diameter of at least 4", with a check valve directly above the discharge outlet. Install the inverter only indoors, in a dry, ventilated room at a temperature of 0–35°C. Installation must be carried out by a qualified installer.
How do I choose the right model from the 4" IBQ IVR series for my well?
The key parameters are the well depth, the dynamic water level, and the required pressure and flow rate of the system. The 4" IBQ IVR series includes models with flow rates from 400 to 800 l/min and a head of up to 195 m. We encourage you to contact our technical department or your local distributor to select the right model.
Where can I buy a 4" IBQ IVR submersible pump?
As a manufacturer, we do not sell directly. 4" IBQ IVR pumps are available from our sales partners, plumbing wholesalers, and authorized online distributors.
What warranty terms apply to the 4" IBQ IVR pump?
IBO – 24-month (2-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat. Service: tel. +48 22 632 86 09, email: serwis@dambat.pl (Mon–Fri, 8:00 a.m.–3:30 p.m.).
