Product Description
FLOWSERVE Intake Suction Bell — Application & Technical Data
What This Part Does
The intake suction bell (also called inlet bellmouth or suction bell) sits at the pump suction nozzle. Its job is to guide incoming fluid smoothly into the impeller eye without turbulence, vortex formation, or flow separation. When the bell wears out or is damaged, you get cavitation noise, vibration, reduced head, and accelerated impeller erosion.
This replacement bell is dimensionally interchangeable with the FLOWSERVE OEM part. We scan the original with FARO 3D laser, rebuild the CAD model, run CFD simulation on the internal flow path, and only proceed to casting when the hydraulic profile matches OEM specifications.
Typical Applications
- Oil & Gas: Crude oil transfer pumps, produced water injection pumps — where sand and H2S create abrasive-corrosive wear
- Petrochemical: Process pumps in refineries and chemical plants — high-temperature service requiring cast steel or stainless steel bells
- Power generation: Condensate extraction pumps, circulating water pumps — large-diameter bells where casting quality directly affects NPSH available
- Mining & mineral processing: Slurry pump feed systems, tailings dewatering — highly abrasive environment calling for wear-resistant cast iron
- Water & wastewater: Raw water intake pumps, sewage lift station pumps — corrosion from H2S and chlorides
- Marine & offshore: Ballast pumps, fire water pumps, cooling seawater pumps — saltwater exposure
- Pulp & paper: Stock preparation pumps, white liquor pumps — fiber-laden fluids
