Problem
The site needed stable water pressure across multiple floors during demand peaks. Inconsistent BWSSB supply pressure was the upstream cause. The risk was uneven guest-room pressure on upper floors, frequent pump cycling, and noise complaints in rooms adjacent to the pump room.
Engineering review
FlowCore reviews fixture demand peak, static head to highest outlet, pipe friction losses, minimum required pressure at the fixture, pressure zoning for high-rise sections, expansion tank sizing, VFD control logic, and dry-run protection before specifying a booster package.
- Peak demand flow vs average day flow — both matter for staging and tank sizing
- VFD pressure control — set point, deadband, and minimum speed
- Expansion tank pre-charge and bladder condition
- Duty-standby pump arrangement
- Pump room noise isolation and vibration mounting
Solution approach
A variable-speed booster package with correctly sized pressure vessels, dry-run protection, service isolation valves, and a commissioned pressure set point matched to the highest fixture requirement on each pressure zone.
What this project confirms
Booster pump selection for hotels combines hydraulics and controls in equal measure. A correctly sized pump with a wrong pressure set point or waterlogged tank produces the same guest complaints as an undersized pump.
