Building on the revolutionary technology of the e.sybox, the e.sybox Max water pump with pressure tank takes integration, efficiency, and modularity to an unprecedented level. This intelligent, variable speed pumping system is engineered to meet the substantial and fluctuating water demands of multi-storey and high-volume applications, ensuring unparalleled comfort and significant operational savings.

Sizing Your System: What Size Water Pump and Pressure Tank Do I Need?

Choosing the right water pump and pressure tank isn’t just about “bigger is better.” It’s about balance. If your equipment is undersized, you’ll deal with weak showers; if it’s oversized, your pump will “short cycle,” leading to a burnt-out motor and expensive repairs.

Here is a simple 3-step guide to sizing your system like a pro.

1. Calculate Your Flow Rate (GPM)

The size of your pump is determined by your home’s peak demand, measured in Gallons Per Minute (GPM).

• The Rule of Thumb: In a standard residential home, count the number of water fixtures (faucets, showers, toilets, dishwashers).

• The Math: A common industry standard is 1 GPM per fixture. If you have 10 fixtures, you need a 10 GPM pump.

2. Determine the “Drawdown” Capacity

The pressure tank doesn’t actually create pressure; it stores it so your pump doesn’t have to turn on every time you flush a toilet.

• The 1-Minute Rule: Most quality pumps should run for at least one minute per cycle to stay cool.

• The Math: If you have a 10 GPM pump, you need a tank that can provide a 10-gallon drawdown (the amount of water delivered between the pump turning off and starting again).

3. Understanding Tank Volume vs. Drawdown

This is where most homeowners get confused. A “20-gallon tank” does not hold 20 gallons of water. Because of the air bladder inside, the actual water available (drawdown) is usually only 25% to 30% of the total volume.

• For a 10-gallon drawdown: you typically need a 30-gallon or 40-gallon physical tank.

Frequently Asked Questions (FAQs)

1. What types of buildings or applications is the e.sybox Max specifically designed for?

The e.sybox Max is designed for commercial building services and medium/large-scale water distribution applications. This includes, but isn’t limited to, high-rise residential complexes (even those over 14 floors), hotels, large apartment buildings, hospitals, and extensive irrigation systems where consistent, high-pressure water boosting is required.

2. What is the maximum number of pumping units that can be grouped together in a single e.sybox Max booster system?

A single e.sybox Max booster system can be configured to include up to four pumps (a quadruple system). This modular design allows the system to meet the flow and pressure demands of very large commercial or multi-unit residential properties.

3. What is the significance of the “O.S.A.” (On Site Assembly) concept for the e.sybox Max?

The On Site Assembly (O.S.A.) concept means the system is composed of modular elements that can be easily assembled directly at the installation site. This simplifies logistics, makes the components easier to handle, and allows for assembly even by a single person, which is a major advantage over traditional, pre-built, bulky booster sets.

4. How does the e.sybox Max’s motor technology contribute to its energy efficiency and quiet operation?

The e.sybox Max uses a water-cooled permanent magnet motor paired with an integrated variable frequency drive (VFD). The VFD ensures the motor speed constantly matches the water demand, optimizing performance and saving energy (up to 20% compared to traditional systems). The water-cooling and sound-deadening casing contribute significantly to its whisper-quiet operation.

5. How are the e.sybox Max units monitored and controlled, particularly in a multi-pump configuration?

The units are monitored and controlled via a high-resolution LCD display and an integrated Wi-Fi module which connects to the DConnect cloud service and app. In a multi-pump set, the units use wireless communication and DSync technology to automatically synchronize their operation after the first pump is configured, allowing for seamless remote monitoring, parameter changes, and system diagnostics.

Empower your large-scale water boosting needs with the ultimate in performance, efficiency, and intelligence. The DAB e.sybox Max is not just a pump system; it’s a future-proof investment in superior water management for Singapore’s most demanding applications.
