What is Submersible Pump Bowl?
Submersible pump bowl is a component for submersible pump (deep well pump or multistage submersible pump), its functions are:.
- Guide fluid flow
- Reduce liquid flow speed, convert liquid kinetic energy into pressure energy, improve pressure
- Eliminate the rotational motion of liquid coming out of impeller, ensure stable flow
- Protect internal components, e.g. impeller, diffuser, bearings, shaft…
Position & Structure
Position: Above the submersible motor, below the discharge pipe.
Structure:
Standard single-stage submersible pump: no bowl, only one impeller + one volute
Single-Stage Well / Deep Well Submersible Pump: One Single Diffuser Bowl + One Impeller
Multiple-Stage Submersible Pump: One Impeller Per Stage + One Bowl Per Stage; Impeller Quantity = Stages; Bowl Quantity = Stages
Material and Manufacturing Technology
| Material | Grades | Manufacturing Technology |
| Cast iron | HT200, GG20, GG25, GG26, FG260, ASTM A48 30/35/40… | Sand casting, shell molding |
| Stainless steel | 304, 316, 2507 | Investment casting |
Manufacturing process
Creating patterns and molds, sand casting uses resin sand, investment casting uses sodium silicate sand
Pouring molten metal into mold, followed by cooling
Sand casting is more widely used for cast iron and cast steel pump bowls
Investment casting is suitable for high-precision stainless steel bowls
Remove sand and get good appearances
Painting, coating or as required
Eliminate casting stress, homogenize microstructure
Get precise dimensions
Difference between pump bowl and pump volute
Pump Bowl
- For multiple submersible pumps or deep well submersible pump use
- Cylindrical straight barrel structure
- Integrated diffuser guide vanes
Pump Volute
- For standard single-stage centrifugal pump use
- Spiral curved housing structure
- No guide vanes
Questions you may have
What casting capabilities do you have?
- Sand casting
- Investment casting (lost wax casting and water glass casting)
- Permanent mold gravity casting
- Die casting
We can produce all metal materials, covering carbon steel, stainless steel, duplex steel, gray iron, ductile iron, brass, aluminium and so on, fully meeting the customized casting and mass production needs of various core pump and valve components, such as submersible pump bowls, pump bodies, and impellers.
How do you handle the complex internal structure of the pump bowl to ensure molding effect and dimensional accuracy?
For sand casting, we use high-strength sand core to ensure smooth surface and high accuracy of internal structure.
For investment casting, we use assembly mold + mold inserts to create integrated wax pattern, to avoid splicing and deformation.
Sand casting Vs. Investment casting, how to choose to produce your pump bowl?
- Cast iron - use sand casting or shell molding
- Stainless steel – use investment casting
- Cast steel with high standard – choose investment casting
- Cast steel with low price – choose sand casting
