BJ 40/55 (0.55kW, 230V) – pump with accessories IPRO
BJ 40/55 set with accessories IPRO is a ready-made solution for automatic water supply, combining the brand's BJ 40/55 pump IPRO with Multi Press 2 electronic pressure switch, glycerin manometer and five-way discharge outlet. The heart of the set is a single-stage, self-suction centrifugal pump, designed for pumping clean and cold water from your own intakes and increasing the pressure in water supply installations. The venturi tube system ensures high suction capacity, and the AISI 304 stainless steel body guarantees durability of the structure even after intensive use.
For whom
- Users of their own water intakes - a set with a digital controller maintains stable water pressure in the entire home installation, with a preview of current operating parameters.
- Water supply system installers - ready-made configuration of pump + Multi Press 2 + pressure gauge + five-way output shortens the process of selecting equipment and simplifies installation of the installation.
- Farms with two pumps or the need for redundancy - Multi Press 2 allows synchronization with a second controller and operation of the main pump with the auxiliary pump.
- Plots and gardens - capacity up to 55 l/min is suitable for powering irrigation, sprinklers and drip lines.
Application
BJ 40/55 set with accessories IPRO is used in water supply installations supplied from their own intakes - dug or deep wells - where it ensures stable water consumption parameters and effective pressure increase. The system with a Venturi tube allows for sucking water from a depth of up to 9 meters, which works well when the water level changes during the season.
The Multi Press 2 electronic pressure switch independently controls starting and stopping the pump, with separately adjustable start and stop pressure and preview of operating parameters on the display. The glycerine manometer ensures stable, clear pressure readings even when the installation is vibrating, and the five-way discharge outlet facilitates the connection of additional system elements. The BJ 40/55 230V hydrophore set operates in single-phase systems, typical for home and allotment installations.
Features
The design of the BJ 40/55 pump is based on a body and shaft made of AISI 304 stainless steel, which translates into corrosion resistance when working with clean water. The impeller and diffuser made of PPO polymer reduce the weight of the device without losing strength, and the mechanical stuffing box in the ceramic/graphite/NBR system protects against leaks on the motor shaft.
Multi Press 2 is equipped with a digital display showing pressure (in bar or psi) and current consumption, and its protections include protection against overload, dry running, too frequent switching on and sensor failure. Manual recovery after detecting an error allows you to control the situation after the protection has been triggered, instead of automatic, uncontrolled resumption.

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 to be drawn from a depth of up to 9 meters without the need to additionally prime the suction system. This solution is particularly useful when the water level in the well varies.
What is the difference between Multi Press 2 and a regular pressure switch?
Multi Press 2 is an electronic pressure switch with a digital display that allows you to separately set the pump on and off pressure and monitors the current operating parameters - pressure and power consumption. Unlike a classic mechanical pressure switch, it also offers protection against dry running, overload and too frequent engine starts.
Does the Multi Press 2 set require an additional expansion tank?
No, the Multi Press 2 controls the pump directly based on the system pressure and does not require an expansion tank, although the BJ 40/55 pump can also operate with a tank if the specific installation requires it.
Is it possible to configure your own set with a custom-made pump?
Yes, it is possible to configure your own custom set. The set can be complemented by a pump, a pressure switch, and other safety devices available in the assortment. To this end, we encourage you to: contact with the service department.
What warranty applies to the BJ 40/55 set with accessories IPRO?
BJ 40/55 set with accessories IPRO is covered by a 36-month (3-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
