Functionality and Pressure Zone Management
A Roof Pressure Stabilizing Pump Station is a small-scale, often dedicated booster system installed on the top floor or roof level of a high-rise building. Its primary function is to boost water pressure specifically for the upper-most floors (the highest pressure zone) that may experience inadequate pressure due to their elevation relative to the main building booster system or rooftop tank.
These systems utilize small, highly efficient booster pumps and VFD control to provide the final pressure lift, ensuring all fixtures in the top zone receive consistent, adequate flow and pressure without over-pressurizing the lower zones.
Specification Table: Roof Stabilizing Station
| Configuration | Compact Skid or Wall-Mounted |
| Pump Type | Vertical Multi-Stage Centrifugal Pump (Quiet Operation) |
| Control | VFD for Constant Pressure Output |
| Max. Head Boost | 10 to 30 meters (Zone-specific) |
| Acoustic Level | Designed for Low Noise Emission (≤60 dB(A)) |
| Power Requirement | Typically Single Phase or Small 3-Phase Motors |
| Sealing | Mechanical Seals (Low Leakage) |
| Weight | Low Weight for Rooftop Structural Loading Requirements |
Application Fields
- Top-floor penthouse apartments and hotel suites requiring premium water pressure.
- Upper floors of commercial office buildings with high water usage fixtures.
- Final pressure boosting for rooftop cooling towers or utility rooms.
- Small-scale boosting in the transfer of water from a rooftop storage tank to a gravity feed system.
- Integrated into the High Pressure Water Mist System as a local zone booster.
Engineering and Custom Fabrication
Our design process includes dynamic analysis of the rooftop structure to ensure the pump operating frequency does not align with the building's natural harmonic frequency, preventing structure-borne noise.
Customization Scope: Custom acoustic enclosures, specific VFD programming for highly sensitive flow control (e.g., medical clinics), and integration with the main building BMS via Modbus for remote monitoring of rooftop pressure status.
All units are tested in the factory to verify noise levels and pressure stability before being shipped to the site.
