Available variations
For which applications is the eSPU-40/5-GR suitable?
The eSPU-40/5-GR is ideal for industrial applications and process industries.
How many simultaneous users can this pressure boosting unit support?
With a flow rate of 105 liters per minute, the unit can provide stable 40-bar water pressure for up to five simultaneous users.
How does the frequency-controlled pump ensure efficiency?
The stainless steel frequency-controlled centrifugal pump automatically adjusts to the water demand, saving energy and eliminating pressure fluctuations. This extends the pump’s lifespan and reduces operational costs.
What are the advantages of the automatic start-stop system?
This system only activates the pump when water is needed and stops it automatically when there is no demand. It minimizes energy use, reduces wear, and extends the unit’s lifespan.
Can the eSPU-40/5-GR be expanded with a water tank?
Yes, the unit can be expanded with a Belgaqua-approved water tank of 200, 400, 800, or 1600 liters, which is useful for installations with variable or limited water supply.
