BJ 40/55 (0.55 kW, 230 V) – pump with IPRO equipment
The BJ 40/55 set with IPRO equipment is a ready-made solution for automatic water supply, combining the IPRO BJ 40/55 pump with the Multi Press 2 electronic pressure switch, a glycerin-filled pressure gauge, and a five-way discharge outlet. At the heart of the set is a single-stage, self-priming centrifugal pump designed for pumping clean, cold water from private water sources and boosting pressure in water supply 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
- Users of private water sources – the set with a digital controller maintains stable water pressure throughout the household installation, with a display of current operating parameters.
- Water supply system installers – the ready-made configuration of pump + Multi Press 2 + pressure gauge + five-way outlet shortens the equipment selection process and simplifies system installation.
- Farms with two pumps or a need for redundancy – Multi Press 2 enables synchronization with a second controller and operation of the main pump together with the auxiliary pump.
- Allotment gardens and gardens – the capacity of up to 55 l/min is suitable for supplying irrigation systems, sprinklers, and drip lines.
Applications
The BJ 40/55 set with IPRO equipment is used in water supply systems fed from private water sources—dug or deep wells—where it ensures stable water intake parameters and effective pressure boosting. The Venturi tube system can draw water from depths of up to 9 meters, making it suitable for fluctuating water levels throughout the season.
The Multi Press 2 electronic pressure switch automatically controls pump starting and stopping, with separately adjustable cut-in and cut-out pressures and a display showing operating parameters. The glycerin-filled pressure gauge provides a stable, clear pressure reading even when the system is subject to vibration, while the five-way discharge outlet makes it easier to connect additional system components. The BJ 40/55 230V booster set operates in single-phase systems typical of household and allotment-garden installations.
Features
The BJ 40/55 pump is built with a body and shaft made of AISI 304 stainless steel, providing corrosion resistance when handling 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.
Multi Press 2 is equipped with a digital display showing pressure (in bar or psi) and current consumption, while its protections include safeguards against overload, dry running, overly frequent starts, and sensor failure. Manual restart after an error is detected allows the situation to be controlled after the protection has been triggered, instead of an automatic, uncontrolled restart.

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 metres without the need for additional priming of the suction system. This solution is particularly useful when the water level in a well varies.
How does Multi Press 2 differ from a regular pressure switch?
Multi Press 2 is an electronic pressure switch with a digital display that allows you to set the pump's cut-in and cut-out pressure separately and view the current operating parameters—pressure and power consumption. Unlike a classic mechanical pressure switch, it also provides protection against dry running, overload, and excessively frequent motor starts.
Does the set with Multi Press 2 require an additional diaphragm tank?
No, Multi Press 2 controls the pump directly based on the pressure in the system and does not require a diaphragm tank, although the BJ 40/55 pump can also operate with a tank if the specific installation requires it.
Is it possible to configure a custom set with a pump to order?
Yes, it is possible to configure a custom set to order. You can select a pump, pressure switch, and other available safety devices for the set. To do so, please contact the customer service department.
What warranty applies to the BJ 40/55 set with IPRO equipment?
The BJ 40/55 set with IPRO equipment is covered by a 36-month (3-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
