HZB double suction volute pump
HZB double suction volute pump
Double suction liquid solutions for tough conditions
- Centerline mounting to allow free thermal expansion and high nozzle loads
- Minimum bearing span to minimize shaft deflection
- Single cover casing design to reduce overhaul times
- Chrome steel casing with good corrosion resistance and excellent mechanical properties is standard; other materials available
- Single mechanical seal provides higher efficiency
- Booster pumps for large boiler feed water units in thermal and nuclear power stations
- Safety-related pumps in nuclear power stations
- Double suction impeller with staggered vanes for low Net Positive Suction Head required (NPSHR) and low-pressure pulsations
- Different nozzle positions are possible
- Amply sized sleeve radial and tilting pad bearings with forced lubrication as standard
- Optional self-contained oil lubricated bearings
- Stiff shaft ensures that critical speed is a minimum of 20 % above the maximum operating speed
- Mechanical seal jacket cooling
