IWH2-03 – pressure booster pump
The IPRO IWH2-03 is a single-stage, self-priming centrifugal pump designed for pumping technically clean, cold raw water from private water sources and for increasing pressure in systems for drawing and pumping this water. As a Dambat product designed for professionals and demanding applications requiring increased reliability, it stands out with a Venturi tube system that provides high suction capability and an AISI 304 stainless steel casing that ensures structural durability even under intensive use.
Who is it for
- Water supply system installers – clear operating parameters and the ability to work with a diaphragm tank or pressure booster controller make it easier to select and quickly install the set.
- Contracting and construction companies – the compact IWH2-03 design enables pressure-boosting sets to be assembled efficiently wherever short installation times are important.
- Technical wholesalers and sales outlets – a proven, versatile self-priming model that complements the range offered to individual customers and contractors.
- Farms and horticultural companies – the pump performs well when supplying basic irrigation systems using technically clean water.
Applications
The IWH2-03 pressure booster pump is used in systems for drawing and pumping raw water supplied from private water sources—dug or deep wells—where it ensures stable water intake parameters and effectively increases pressure. The Venturi tube system allows water to be drawn from depths of up to 9 metres, which is useful when the water table varies throughout the season. The pump does not treat water; when using it for other purposes, we recommend ensuring appropriate water treatment.
In installation practice, this model is used both to build complete pressure booster sets in single-family homes and in simpler irrigation systems on allotments and farms. The IWH2-03 230V pressure booster pump works with a diaphragm tank and pressure booster controllers, allowing the set configuration to be adapted to the specific installation.
Features
The IWH2-03 is constructed with a casing, shaft, and intermediate wall made of AISI 304 stainless steel, providing corrosion resistance when handling technically clean water. The AISI 316 stainless steel impeller offers additional corrosion resistance, including in water with elevated chloride content, while the PPO polymer diffuser reduces the unit’s weight without compromising its strength.
The motor has built-in thermal protection in the winding, protecting the pump from overheating during extended continuous operation. The IP55 degree of protection and insulation class F enable safe operation in typical utility rooms and pressure-booster rooms.

Frequently asked questions
How does the Venturi tube system in the IWH2-03 pump work?
The Venturi tube increases the pump's suction capacity, enabling water intake from depths of up to 9 meters without the need to prime the suction system before startup. This solution is particularly useful when the water level in the well varies.
Can the IWH2-03 operate with a hydrofor controller or a diaphragm tank?
Yes, the pump is designed to work with both a diaphragm tank and hydrofor controllers, allowing you to build a complete system for increasing and stabilizing pressure in the installation.
Which installations is the IWH2-03 best suited for?
The IWH2-03 is best suited for raw-water intake and pumping systems supplied from private water sources—dug or deep wells—in single-family homes, as well as simpler irrigation systems on allotments and farms.
What is the difference between the IWH2-03 and the IWH3-04?
The IWH2-03 is a smaller, less powerful unit with lower power consumption, suitable for basic water intake from a private water source. The IWH3-04 offers greater head and capacity, making it suitable for higher water demand.
What warranty applies to the IPRO IWH2-03 pump?
The IPRO IWH2-03 pump is covered by a 36-month (3-year) manufacturer's warranty, while warranty and post-warranty service is provided by Dambat. For maintenance or repairs, it is advisable to contact the service department directly.
