WZI 750 pressure booster 50 – 230 V pressure booster set with a 50 L tank
The WZI 750 with a 50 L pressure tank is a pressure booster set for the automatic intake and delivery of raw water in residential properties. It combines a single-stage, self-priming WZI 750 peripheral pump with a power rating of 0.75 kW, a 50 L diaphragm tank, and pressure control equipment. When a water outlet is opened, the pump starts automatically, and when it is closed, the pump switches off – the system operates without manual control.
Who it is for
-
Owners of single-family homes with their own water source – the WZI 750 pressure booster set maintains stable water pressure throughout the household plumbing system.
-
Owners of holiday homes and allotments – the compact system with a 50 L tank supplies water from a private well without a connection to the mains water supply.
-
Users who value durability – the pump’s brass impeller provides resistance to abrasion and a long service life for the hydraulic system.
-
Water system installers – the built-in check valve and factory-selected equipment reduce the time required to assemble and commission the installation.
Applications
The IBO WZI 750 pressure booster set with a 50 L pressure tank is designed for the automatic intake and delivery of technically clean, cold raw water in single-family homes, holiday homes, allotments, and smaller farms. Its suction capacity reaches up to 8 m, while its maximum head of 60 m is suitable for long installation runs. The set delivers water from wells, tanks, and private water sources, and it also increases pressure in the system supplying the installation. The set is not a water treatment device – when the water is used for other purposes, we recommend ensuring appropriate treatment.
The pressure switch automatically starts and disconnects the pump depending on the pressure in the system, while the 50 L diaphragm tank stabilizes the pressure and reduces the frequency of motor starts. The equipment dedicated to the pump and selected at the factory simplifies the assembly and installation process. The set operates on a 1~ 230 V / 50 Hz power supply.
WZI 750 pressure booster 50 features – description and technical data
The set is based on a single-stage, self-priming peripheral pump with a built-in check valve that protects the installation against water backflow and eliminates the need to install an external check valve. The pump housing is made of cast iron, the shaft is made of AISI 304 stainless steel, and the impeller is made of brass, ensuring durability and resistance to abrasion. Thermal protection is built into the motor winding.
The pressure gauge is mounted on the five-way discharge outlet, which creates a single connection point for the tank, installation, and control equipment – this facilitates routing the installation in multiple directions. The anti-vibration hose with an elbow limits the transmission of pump vibrations to the tank and piping.
In addition to the standard pump + tank configuration, the WZI 750 pump itself can be connected to PC or SK series pressure booster controllers, as well as to the IVR-02 frequency converter. These controllers also protect the pump against dry running. The range of controllers dedicated to IBO pressure booster sets is available on our website.

Frequently asked questions (FAQ) – WZI 750 pressure booster 50 set
What is included in the WZI 750 pressure booster 50 set?
The set includes: WZI 750 pump, 50 L diaphragm tank, anti-vibration hose with an elbow, five-way discharge outlet, pressure gauge, and pressure switch. Additional equipment and tanks with other capacities can be found here.
What are the benefits of a brass impeller in the WZI 750 pump?
The brass impeller provides high resistance to abrasion and a long service life for the hydraulic system. Combined with the built-in check valve, which protects the installation against water backflow, it creates a durable, maintenance-free system.
What tank capacity should I choose for the set?
The WZI 750 pump can be paired with tanks with capacities of 24, 50, 80, 100, and 150 L, available in horizontal, vertical, and stainless-steel versions. A larger tank starts the pump less frequently and provides a greater water reserve, while a smaller one takes up less space. To select a configuration suited to your individual needs, contact the Dambat technical department.
Does the set operate automatically?
Yes – the pressure switch starts the pump when a water outlet is opened and switches it off when the outlet is closed. The diaphragm tank stabilizes the pressure and reduces the frequency of motor starts.
Can the WZI 750 pump be connected to a pressure booster controller?
Yes – in addition to the standard configuration with a diaphragm tank, the WZI 750 pump can be paired with PC or SK series pressure booster controllers, or with an IVR series frequency converter. These controllers provide additional dry-running protection. The appropriate configuration should be selected in consultation with our technical department.
Is the WZI 750 pressure booster 50 set covered by the manufacturer’s warranty?
IBO – 24 months (2 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
Where can I buy the WZI 750 pressure booster 50 set?
As a manufacturer, we do not sell directly. The set is available from our commercial partners, plumbing wholesalers, and authorized online distributors.
