DP 355 pressure booster 50 – 230 V pressure booster set with a 50 l tank
DP 355 with a 50 l pressure tank is a pressure booster set for automatically drawing and pumping untreated water in households. It combines a single-stage, self-priming DP 355 surface pump with a power rating of 1.1 kW, a 50 l diaphragm tank, and pressure control. Thanks to the Venturi tube system and return piping, the pump draws water from depths of up to 23 m – significantly deeper than standard surface pumps. When a water outlet is opened, the pump starts automatically, and when it is closed, the pump switches off.
Who it is for
-
Owners of homes and plots with deep water sources – the DP 355 pressure booster set draws water from depths of up to 23 m, where standard surface pumps are unable to operate.
-
Farms and irrigation systems – reliable operation with fluctuating water levels in the source makes it suitable for supplying sprinklers and drip lines.
-
Owners of drilled wells – deep suction enables water to be drawn from sources with a low or fluctuating water table.
-
Water system installers – the set, supplied with selected accessories, reduces the time required to complete and commission a pressure installation.
Applications
The IBO DP 355 pressure booster set with a 50 l pressure tank is designed for automatically drawing and pumping technically clean, cold untreated water in single-family homes, farms, recreational facilities, and plots. Its suction capacity reaches up to 23 m and is achieved using return piping lowered into the well. The set pumps water from drilled wells, private water sources, and tanks, and also increases pressure in systems supplying installations. The set is not a water treatment device – when using the water 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 pressure and reduces the frequency of motor starts. Factory-selected accessories dedicated to the pump simplify the process of completing and installing the system. The set operates on a 1~ 230 V / 50 Hz power supply.
DP 355 pressure booster 50 – features, description, and technical data
The set is based on a single-stage, self-priming centrifugal pump with a suction system based on a Venturi tube and return piping, enabling the pump to draw water from depths of up to 23 m. Thermal protection is built into the motor winding and protects it against overheating.
The pressure gauge is installed on the five-way discharge outlet, which creates a single connection point for the tank, installation, and control system – making it easier to distribute 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 DP 355 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. Our pressure booster controllers offer includes controllers dedicated to IBO pressure booster sets.

Frequently asked questions (FAQ) – DP 355 pressure booster 50 set
What is included in the DP 355 pressure booster 50 set?
The set includes: DP 355 pump, 50 l diaphragm tank, anti-vibration hose with elbow, five-way discharge outlet, pressure gauge, and pressure switch. You can find the remaining dedicated accessories and tanks with other capacities in our pressure booster sets offer.
How does the DP 355 differ from standard surface pumps?
The DP 355 draws water from depths of up to 23 m thanks to its Venturi tube and return piping, while standard surface pumps usually draw water from depths of up to 8 m. It is suitable wherever the water level in the source is low or fluctuating, for example in drilled wells.
What tank capacity should I choose for the set?
The DP 355 pump can be paired with tanks of various capacities, 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 for 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 pressure and reduces the frequency of motor starts.
Can the DP 355 pump be connected to a pressure booster controller?
Yes – in addition to the standard configuration with a diaphragm tank, the DP 355 pump can be paired with PC or SK series pressure booster controllers, or with an IVR series frequency converter. These controllers provide additional protection against dry running. We recommend consulting our technical department when selecting the appropriate configuration.
Does the DP 355 pressure booster 50 set come with a manufacturer’s warranty?
IBO – 24 months (2 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
Where can I buy the DP 355 pressure booster 50 set?
As a manufacturer, we do not sell directly. The set is available from our trading partners, installation wholesalers, and authorized online distributors.
