Client: Sunrise Residences Tower, Manila, Philippines
Industry: Residential & Commercial Building – Water Supply Boosting
Product used: YISA Multi-Stage Surface Booster Pump Set (7.5kW, 3-phase)
Sunrise Residences Tower is a 22‑story condominium with over 180 units. The building relies on a rooftop water tank fed by the municipal water line. However, during peak hours (morning and evening), the water pressure on upper floors (above the 15th floor) dropped dramatically. Residents complained of weak shower flow, slow tank filling, and occasional dry taps.
The existing single pump system was undersized, unreliable, and frequently overheated. The building management needed a high‑head, stable‑flow, low‑maintenance boosting system that could handle variable demand without constant breakdowns.
Key requirements:
Flow rate: 25–30 m³/h during peak hours
Head pressure: sufficient to reach 22nd floor (approx. 80m height)
Reliable operation with Philippine voltage (220V/60Hz, 3-phase)
Energy efficiency – to reduce common area electricity bills
After a site visit and hydraulic calculation, our engineering team proposed a YISA horizontal multi‑stage surface pump booster set including:
2 x YISA 7.5kW multi‑stage centrifugal pumps (duty/standby configuration)
Variable frequency drive (VFD) for constant pressure control
Stainless steel pump head for corrosion resistance
Pressure tank & sensor for smooth start/stop cycles
Why YISA was selected:
Custom 60Hz motor winding suited to Philippines grid
VFD included – saves up to 30% energy compared to constant‑speed pumps
Compact footprint – fits existing pump room
18‑month warranty and spare parts availability
We provided:
Full installation drawing and electrical schematics
Remote commissioning support via video call
Spare mechanical seal and impeller kit shipped with the order
The new booster set was installed during a weekend to minimize disruption. After one month of operation, the building management reported the following outcomes:
| Metric | Before (Old Pump) | After (YISA Booster Set) |
|---|---|---|
| Upper floor water pressure | 0.8 – 1.2 bar (insufficient) | 2.8 – 3.2 bar (steady) |
| Complaints from residents | 12–15 per week | 0 per week |
| Daily energy consumption | 85 kWh | 58 kWh (↓ 32%) |
| Pump breakdowns | Every 2–3 months | None (running 24/7) |
| Noise level | Loud (75 dB) | 55 dB (quiet operation) |
“We should have switched to YISA pumps years ago. The constant pressure is perfect – even on the 22nd floor, showers feel strong and consistent. The VFD saves us real money every month. The installation support via WhatsApp was surprisingly smooth. Highly recommended for any building manager facing pressure issues.”
– Mr. Ricardo M., Property Manager, Sunrise Residences Tower
