DAB Esybox Mini 3: Constant Pressure Water Pump for Homes and Residential Applications

Does your water pressure drop every time someone opens another faucet or turns on a second shower? Low and unstable water pressure is a common problem in homes, apartments and multi-story residential properties.

The DAB Esybox Mini 3 1 HP Electronic Constant Pressure Water Pump is designed to provide comfortable, stable and efficient water pressure throughout your home.

Unlike a conventional water pump, the Esybox Mini 3 features advanced variable speed technology that automatically adjusts pump performance according to the actual water demand.

The result is a compact, quiet and intelligent water pressure system designed to deliver consistent pressure when you need it most.

What is the DAB Esybox Mini 3?

The DAB Esybox Mini 3 is a compact electronic water pressure boosting system designed primarily for residential water supply applications.

It combines several components normally required in a traditional pressure system into one complete and compact solution.

• Multistage water pump.
• Variable speed drive.
• Pressure sensor.
• Flow sensor.
• Integrated expansion tank.
• Check valve.
• High-resolution LCD display.

How Does a Constant Pressure Water Pump Work?

This is one of the biggest differences between the DAB Esybox Mini 3 and a traditional water pump.

A conventional pump typically operates at a fixed speed. When it starts, the motor runs at its rated speed whether the home requires a small or large amount of water.

The Esybox Mini 3 works differently.

When someone opens a faucet or turns on a shower, the integrated sensors detect the water demand and the electronic control system automatically adjusts the motor speed to help maintain the selected water pressure.

For example:

• One shower running: the pump delivers the required flow.
• Shower + bathroom faucet: the pump automatically increases its performance.
• Shower + bathroom faucet + kitchen: the system adjusts again to meet the increased water demand.

When all water outlets are closed, the system detects that water demand has stopped and automatically shuts the pump down.

This means the pump does not need to operate at full speed all the time.

Enjoy Constant Water Pressure Throughout Your Home

The main purpose of the Esybox Mini 3 is to provide stable and comfortable water pressure throughout the plumbing system.

This can make a major difference in homes where several water outlets are used at the same time.

The system can improve water pressure for applications such as:

• Showers.
• Bathroom faucets.
• Kitchen faucets.
• Bathrooms.
• Washing machines.
• Dishwashers.
• Residential irrigation systems.
• Outdoor faucets.

When correctly sized for the application, the pump continuously adjusts its operating speed to respond to changes in water demand.

A Quiet Water Pump Designed for Residential Comfort

One of the standout advantages of the DAB Esybox Mini 3 is its low operating noise.

DAB designed the system to reduce both motor noise and vibration, making it especially suitable for residential installations.

Under specific operating and measurement conditions, the Esybox Mini 3 can operate at approximately 45 dB(A).

This makes it an excellent choice when the water pressure system must be installed near bedrooms, living areas, utility rooms or other locations where noise is an important consideration.

Energy Efficiency with Variable Speed Technology

The Esybox Mini 3 features an integrated variable speed drive that automatically adjusts motor speed according to actual water demand.

For example, filling a glass of water does not require the same amount of pump performance as operating two showers and a bathroom faucet at the same time.

The Esybox Mini 3 recognizes these changes and automatically adapts its operation.

Lower water demand allows the pump to operate at a lower speed.

This technology helps optimize pump operation and can improve energy efficiency compared with traditional fixed-speed pumping systems.

An All-in-One Water Pressure System

A traditional constant pressure installation may require several separate components.

For example:

Water pump + variable frequency drive + pressure sensors + pressure tank + valves + control system.

The DAB Esybox Mini 3 takes a different approach.

Many of these components are integrated into one compact system.

This provides several important advantages:

• Compact installation.
• Fewer external components.
• Reduced installation space.
• Clean and professional appearance.
• Integrated electronic control.
• Easy system configuration.
• Simplified residential water pressure installation.

How is the DAB Esybox Mini 3 Installed?

One of the most common applications is using the Esybox Mini 3 to pressurize water coming from a storage tank.

A typical installation follows this layout:

WATER STORAGE TANK → DAB ESYBOX MINI 3 → HOME PLUMBING SYSTEM

The suction line from the water tank connects to the inlet of the Esybox Mini 3. The pump discharge then connects directly to the home's plumbing system.

Once the hydraulic and electrical connections are correctly completed, the Esybox Mini 3 automatically controls pump operation according to water demand.

For a typical installation, the system does not require an external pressure switch, external variable speed controller or a large conventional pressure tank for normal operation.

Where Can the DAB Esybox Mini 3 Be Used?

Thanks to its compact design and intelligent control system, the Esybox Mini 3 can be used in a wide range of residential water pressure applications.

• Single-family homes.
• Apartments.
• Multi-story homes.
• Country homes.
• Homes supplied from water storage tanks.
• Potable water systems.
• Small residential buildings.
• Homes experiencing low water pressure.
• Residential systems with multiple simultaneous water outlets.

Is the Esybox Mini 3 Suitable for a Two or Three-Story Home?

A common question is whether the DAB Esybox Mini 3 can supply a two or three-story home.

The answer depends on the hydraulic requirements of the property.

Choosing a water pump based only on the number of floors is not recommended.

A proper pump selection should also consider:

• Number of bathrooms.
• Number of showers.
• Number of fixtures operating simultaneously.
• Vertical elevation between the water source and fixtures.
• Horizontal pipe distance.
• Pipe diameter.
• Required water pressure.
• Friction losses in the plumbing system.

Although the Esybox Mini 3 can deliver up to approximately 80 liters per minute, the actual available flow depends on the pressure required by the system.

Ideal for Homes with Water Storage Tanks

One of the most popular applications for the DAB Esybox Mini 3 1 HP is boosting water pressure from a residential storage tank.

The entire process is automatic:

1. A faucet, shower or other water outlet is opened.
2. The system detects the pressure drop and water demand.
3. The pump starts automatically.
4. The variable speed drive adjusts the motor speed.
5. Water is supplied to the home.
6. The system works to maintain the selected pressure.
7. When water demand ends, the pump automatically stops.

No manual pump operation is required during normal use.

Does the Esybox Mini 3 Require a Pressure Tank?

No large external conventional pressure tank is required for normal operation.

The DAB Esybox Mini 3 includes an integrated expansion tank inside the unit.

This helps make the installation much more compact compared with traditional booster pump systems that use large external pressure tanks.

Special applications may require additional components depending on the specific characteristics of the hydraulic system.

Does the Esybox Mini 3 Require a Pressure Switch?

No. The DAB Esybox Mini 3 features integrated electronic pressure control, eliminating the need for a conventional external mechanical pressure switch in a typical installation.

The electronic system automatically determines when the pump should start, stop and change operating speed.

Can the Esybox Mini 3 Draw Water from a Tank Below the Pump?

Yes. The Esybox Mini 3 can operate in suction lift applications where water must be drawn from a tank located below the pump.

The stated maximum suction lift can reach approximately 8 meters, although actual performance depends on installation conditions.

Important factors include:

• Elevation above sea level.
• Suction pipe diameter.
• Suction pipe length.
• Number of fittings and valves.
• Air-tightness of the suction line.
• Water temperature.

For optimum performance, the pump should always be installed as close as practical to the water source.
