BJ 40/55 – booster pump
The BJ 40/55 is an IPRO brand pump from the Dambat line, dedicated to professionals and applications requiring increased reliability. It 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 water intake and delivery systems. The Venturi tube system provides high suction capacity, while the AISI 304 stainless steel body ensures structural durability even under intensive use.
Who is it for?
- Water-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 a set in single-family homes and recreational plots.
- Contracting and construction companies—the compact BJ 40/55 design enables pressure-boosting sets to be assembled efficiently wherever short installation times matter.
- Technical wholesalers and sales outlets—a proven, self-priming model with versatile applications, complementing the range for individual customers and contractors.
- Farms and horticultural companies—the pump performs well when supplying basic irrigation systems using technically clean water.
Applications
The BJ 40/55 booster pump is used in raw-water intake and delivery systems supplied from private water sources—dug or deep wells—where it provides stable water intake parameters and effectively increases pressure. The Venturi tube system allows water to be drawn from depths of up to 9 meters, making it suitable for varying water levels throughout the season. The pump is not a water-treatment device; when using it for other purposes, we recommend ensuring appropriate water preparation.
In installation practice, this model is used both to build complete pressure booster sets in single-family homes and recreational plots, and in simpler irrigation systems. The BJ 40/55 230V booster pump works with a diaphragm tank and pressure booster controllers, allowing the set configuration to be adapted to the specific installation.
Features
Tested according to IPRO brand standards, the BJ 40/55 construction is based on a body and shaft made of AISI 304 stainless steel, providing corrosion resistance when handling technically clean water. The PPO polymer impeller and diffuser reduce the unit’s weight without compromising strength, while the ceramic/graphite/NBR mechanical seal prevents leaks along the motor shaft.
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 F insulation class allow safe operation in typical utility rooms and hydrofor rooms, in accordance with the requirements for IPRO-class equipment.

Frequently asked questions
How does the Venturi tube system in the BJ 40/55 pump work?
The Venturi tube increases the pump’s suction capacity, enabling water intake from depths of up to 9 meters without the need for additional priming of the suction system. This solution is particularly useful when the water level in the well varies.
Can the BJ 40/55 operate with a hydrofor controller or 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 BJ 40/55 best suited for?
The BJ 40/55 is best suited to raw-water intake and delivery systems supplied by private water sources—dug or deep wells—in single-family homes, recreational plots, and simpler irrigation systems.
How does the BJ 40/55 differ from the BJ 60/100?
The BJ 40/55 is a smaller, less powerful unit with lower power consumption, suitable for basic water intake from a private source. The BJ 60/100 offers greater head and capacity, making it suitable for higher water demand or longer installations.
What warranty applies to the IPRO BJ 40/55 pump?
The IPRO BJ 40/55 pump is covered by a 36-month (3-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
