Description
BJ 40/55 (0.55kW, 230V) – pump IPRO with Water Pass 2 controller
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 an intelligent Water Pass 2 controller, a glycerin manometer and a 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 - the 1 l tank built into Water Pass 2 reduces water hammer and smoothes the operation of the installation when opening and closing the water intake.
- Water supply system installers - ready configuration pump + Water Pass 2 + pressure gauge + five-way output shortens the process of selecting equipment and simplifies installation of the installation.
- People looking for simple start-up without programming - Water Pass 2 calibrates itself to the set pressure, without the need to manually configure the thresholds.
- 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 intelligent Water Pass 2 controller examines changes in pressure and water flow in the pipeline, independently starting and stopping the pump depending on the current consumption - the built-in check valve protects the system against water returning to the pump, and the integrated 1-liter tank reduces pressure peaks each time it is turned on. 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.
Water Pass 2 protects the pump against dry running by automatically turning it off after detecting a lack of water in the installation, and the built-in 1 l tank limits the frequency of engine starts with small, temporary water consumption. The controller is universal - it works with both surface and hydrophore pumps, as well as deep-well, submersible and vertical pumps.

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 built-in 1 liter tank in the Water Pass 2 controller used for?
The 1-liter tank limits hydraulic shocks occurring each time the pump is turned on and off and reduces the frequency of its activation with small, temporary water consumption, which extends the engine's life.
Does the Water Pass 2 set require an additional expansion tank?
No, Water Pass 2 has its own, integrated 1 l tank and controls the pump independently based on the pressure and flow in the installation - it does not require a separate expansion tank.
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.
