Ritz Hotel high-rise fire pump system export ｜ La Paz, Bolivia

Application scenario: high-end hotel, 78 m / 22 floors, altitude 3650 m (world’s highest capital). NFPA20 compliance required. Low oxygen conditions increase cavitation risk; large temperature difference 5–28℃ causes freezing at night; strong UV + dust condensation corrosion; 230V unstable grid 190–260V; original pumps lacked altitude compensation, poor pressure, impellers failed every 3–4 months, winter freezing caused short circuits, Chinese control cabinet unusable locally, long 45-day spare parts cycle, no diesel backup, non-compliant with NFPA20.

 

Solution content: M&W ENERGY SAVING supplied DG multistage fire pump system + diesel backup + jockey pump: DG150-50×8 electric main pump (160 m³/h / 320 m, 2 units 1 standby, 230V high-altitude motor +15% power margin, 304 stainless wide flow anti-cavitation), turbocharged intercooled diesel backup pump (water jacket heating + fuel preheat + low-temp battery cold start), DG46-50×4 jockey pump (2 units 1 standby). 230V wide-voltage adaptation; Spanish control cabinet with auto test / duty-standby switching / diesel linkage; NFPA20 compliant. Electric tracing anti-freeze; IP54 moisture protection; IPPC export packaging; Spanish + English manuals; onsite commissioning; 2-year spare parts; 3-year remote Spanish support.
