Constant pressure delivers the same comfort on every floor
The frequency-converter panel keeps outlet pressure constant even as demand changes; the tap on the top floor flows just as smoothly as the one on the ground floor.

Booster Pump Systems
Booster pump systems keep water at the desired, constant pressure in buildings and facilities where mains pressure falls short. The frequency-converter control panel automatically adjusts pump speed to instantaneous demand, optimizing energy use; available in single- or multi-pump, stainless multistage casing options, they are commissioned on domestic water, fire and process lines.

Why it matters
What does a booster pump system do?
It keeps water at constant pressure on upper floors and process lines where mains pressure is insufficient.
The frequency-controlled panel optimizes energy use
Pump speed adjusts to instantaneous demand; electricity consumption drops noticeably compared with fixed-speed systems.
A multi-pump setup provides redundancy
Multiple pumps engage in sequence or in parallel; if one fails, the system keeps running without a water outage.
Dry-run protection protects the pump
When inlet pressure or water level drops, the system shuts down automatically, preventing the pump from running dry and being damaged.
Types
Sub-types of booster pump systems
All three keep outlet pressure constant; what sets them apart is the pump count and control logic.
Single-pump booster system
A simple, economical solution preferred for small residential and commercial installations with low-to-medium flow and a single consumption line.
- Low investment cost
- Small/medium-scale installation
- Simple commissioning
Multi-pump (staged) booster system
Multiple pumps engage in sequence or in parallel according to demand; used in buildings and facilities that need redundancy and high flow rate.
- Automatic backup
- High flow capacity
- Uninterrupted water supply
Frequency-converter (VFD) booster system
Pump speed is continuously adjusted to demand; there is no pressure fluctuation, and energy use is kept to a minimum.
- The lowest energy consumption
- Fluctuation-free pressure
- Suitable for fire and domestic water use

FAQ
Questions from the field
The questions we hear most often when quoting booster pump systems.
How many pumps does the system need?
A single pump is enough for small installations with one consumption line. For buildings and process lines that need redundancy or high flow rate, a multi-pump setup (2-6 pumps) is preferred.
What is the difference between a fire booster system and a domestic water booster system?
A fire booster system keeps the high flow rate and pressure needed in a fire event constantly ready; it is usually a separate system. A domestic water booster system meets daily water demand; the two can be combined into one system, but designing them separately is recommended.
What happens if mains pressure is cut off entirely?
If the system is fed from an intermediate tank or reservoir, water supply continues. If it is fed directly from the mains, dry-run protection kicks in and the pumps stop automatically; no water can be delivered during the outage.
How often does it need maintenance?
An annual periodic maintenance checks the pressure settings, dry-run sensors and pump shaft seals; for systems that run continuously, this interval can be shortened.
Do you only serve Istanbul?
No. While our office is on Istanbul's Anatolian side (Ataşehir), we supply and ship across Istanbul's European side, the surrounding provinces and the Marmara region, and Turkey as a whole — covering your equipment end to end, from a single source.
