The TORISHIMA HAV/HLAV is a glandless (sealless) pump motor unit for boiler circulating pump application with pump and motor being integrated in a pressure-tight casing.
The glandless design (no shaft seal) makes this pump best suited for pumping of high temperature and high pressure liquids without any leakage at all.
The pump is driven by Torishima made high performance three phase induction motor filled with water (wet motor).
This pump is used mainly for ciculation of water at high pressures and temperatures for which the use of shat seal is technically and/or economically inappropriate. Main fields of applications are boilers designed for super critical pressure and sliding pressure operation and others like,
- Forced circulation boiler
-Once through boiler
-Controlled circulation boiler
-Combined circulation boiler
-Waste heat recovery boiler in steel works, etc.
-Heating boiler for various process plants
-Other various boilers for marine and land use
-High pressure and high temperature testing facilities
