Description
BJ 40/55 – 230 V pressure booster set with a 50 L FIX tank
The BJ 40/55 pump with a 50 L FIX pressure tank is a set for the automatic intake and transfer of raw water in households before treatment. The IPRO line is designed for professional and demanding applications requiring increased reliability. At the heart of the set is a single-stage, self-priming centrifugal pump intended for pumping technically clean, cold raw water from private water sources and for increasing pressure in the water intake and transfer system. The Venturi tube system provides high suction capability, while the AISI 304 stainless steel casing ensures structural durability even under intensive use.
Who it is for
- Users of private water sources – The pressure booster set maintains stable water pressure throughout the household installation.
- Allotments and gardens – a capacity of up to 55 L/min is suitable for supplying irrigation systems, sprinklers, and drip lines
- Wholesalers and technical retail outlets – a proven set with a versatile self-priming model, complementing the product range for individual customers and contractors.
- Water system installers – the set includes selected, dedicated accessories, shortening the equipment selection process and simplifying installation.
Applications
The BJ 40/55 pressure booster pump set with a 50 L FIX tank is used in raw-water intake and transfer systems supplied from private water sources – dug or deep wells – where it ensures stable water intake parameters and effective pressure boosting. The Venturi tube system allows water to be drawn from depths of up to 9 metres, making it suitable for fluctuating water levels throughout the season. The set does not treat water – if water from a private source is to be used for drinking, it must be appropriately treated and its quality monitored.
In installation practice, this set is used both to create complete pressure booster systems in single-family homes and recreational allotments, and in simpler irrigation systems. The 50 L FIX diaphragm tank stabilises pressure and reduces the frequency of motor starts, extending the service life of the installation. The factory-selected dedicated accessories simplify the process of completing and installing the system. The set operates on a 230 V / 50 Hz power supply.
Features
Tested in accordance with IPRO brand standards, the BJ 40/55 is based on a casing and shaft made of AISI 304 stainless steel, providing corrosion resistance when operating with technically clean water. The PPO polymer impeller and diffuser reduce the unit’s weight without compromising durability, while the ceramic/graphite/NBR mechanical seal prevents leaks around the motor shaft.
The motor has built-in thermal protection in the winding, protecting the pump from overheating during extended continuous operation. The IP55 protection rating and F insulation class enable safe operation in typical utility rooms and pressure tank rooms, in accordance with the requirements for IPRO-class equipment.
In addition to conventional pump-and-tank sets, the pump can also be configured with pressure booster controllers from the following series: PC, SK, as well as the electronic pressure switch Water Pass 2. These controllers provide additional dry-run protection.

Frequently asked questions
How does the Venturi tube system work in the BJ 40/55 pump?
The Venturi tube increases the pump’s suction capability, enabling water to be drawn 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 the well fluctuates.
Is it possible to configure a custom pump set to order?
Yes, it is possible to configure a custom set to order. The set can be equipped with a selected pump, pressure switch, and other protective devices available in our range. To do so, please contact our customer service department.
Which installations are best suited to the BJ 40/55 set with a 50 L FIX tank?
The BJ 40/55 set with a tank is best suited to raw-water intake and transfer systems supplied from private water sources – dug or deep wells – in single-family homes, recreational allotments, and simpler irrigation systems.
What is the difference between the BJ 40/55 and BJ 60/100?
The BJ 40/55 is a smaller, lower-capacity 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 set with a 50 L FIX tank?
The IPRO BJ 40/55 set with a tank is covered by a 36-month (3-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
