YISA Surface Booster Pump Solves Water Pressure Problem for Condominium in the Philippines

YISA Surface Booster Pump Solves Water Pressure Problem for Condominium in the Philippines

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)


The Challenge

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


The YISA Solution

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 Results

The new booster set was installed during a weekend to minimize disruption. After one month of operation, the building management reported the following outcomes:




MetricBefore (Old Pump)After (YISA Booster Set)
Upper floor water pressure0.8 – 1.2 bar (insufficient)2.8 – 3.2 bar (steady)
Complaints from residents12–15 per week0 per week
Daily energy consumption85 kWh58 kWh (↓ 32%)
Pump breakdownsEvery 2–3 monthsNone (running 24/7)
Noise levelLoud (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


Why This Project Matters

This project demonstrates that YISA surface booster pumps are a dependable solution for commercial and residential high‑rise buildings:

  •  Solves pressure problems on top floors

  •  Energy‑saving VFD technology reduces operating costs

  •  Duty/standby design ensures 24/7 water supply

  •  Remote technical support makes installation easy, even across borders


Other Applications for YISA Surface Pumps

  • Hotel water boosting

  • Hospital constant pressure systems

  • Small factory water supply

  • Garden irrigation (commercial)

  • Industrial water circulation
