Flowserve SIHI Application
Flowserve SIHI series HEGA multistage centrifugal pumps are used in applications where
the requirement is for trouble-free pumping of clear or slightly dirty liquids. They are used in :
- Heating Plants
- Boiler Feed Water Plants
- Fire Extinguishing Plants, etc
Flowserve SIHI Design
Flowserve SIHI multistage horizontal centrifugal pumps with sectional casing and closed impellers.
The manufacturing program covers six sizes, with 2 up to maximum 13 stages, accoring to the size,
the speed and the shaft seal. The impellers, diffusers are well as the wear ring from size 65 are
intechangeable between stages.
