submersible pumps are vertical, multi stage, centrifugal pumps with motor at the bottom & pump at the top. The water enters at the bottom of the pump and flows upwards through many stages. The stainless steelbronze impellers rotate inside the diffusers with inherent guide vanes. The diffusers direct water leaving each impeller towards the suction opening of the next impeller. Such a flow through each stage of impeller and diffuser combination adds pressure at each stage and finally water under high pressure is discharged through outlet at the top.

our customers with pumps but also all other equipment forming part of a fixed system for fire-fighting. We offer the necessary sprinkler pumps, pressure booster systems and all-in solutions from a single source. This shows once more that PEW can provide both custom-engineered solutions and standard systems.All our fire pumps are capable of furnishing not less than 150% of rated capacity at head not less than 65% of the rated head. The shut off head does not exceed 120% of rated head.The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature and subsequently open, releasing water. Alternately other fire hoses, reels or other fire fighting connections are opened, causing a pressure drop in the fire fighting main.
