Inline Eductors — When to Choose
- →Transferring liquid from one location to another
- →Pumping slurries, solids, or corrosive fluids
- →Priming centrifugal pumps
- →Vacuum generation (steam/gas motive)
- →Gas scrubbing or odor control
- →Direct steam injection heating (MLE)
- →Applications requiring self-priming capability
- →Hazardous area — no electrical at pump location
Tank Eductors — When to Choose
- →Blending or mixing contents within a tank
- →Preventing stratification in storage tanks
- →Suspending solids or slurries in a vessel
- →Equalizing temperature throughout a tank
- →Eliminating agitator shafts, seals, and motors
- →Direct steam injection tank heating (no heat exchanger)
- →Open or enclosed tanks across food, chemical, refining
- →Compact in-tank mounting — no overhead structure
Material Selection Guide
| Material | Typical Service | Max Temp | Notes |
|---|---|---|---|
| Bronze | Water, steam, general service | 400°F | Standard; most economical |
| Carbon Steel | Higher pressures, non-corrosive | 600°F | Good for steam & oil service |
| 316 SS | Corrosive liquids, acids, caustics, food-grade | 600°F | Most common alloy upgrade |
| 304 SS | General corrosion resistance | 600°F | Lower cost than 316 SS |
| Alloy 20 | Sulfuric acid, highly corrosive chemical | 500°F | Excellent sulfuric acid resistance |
| Hastelloy C | Extremely aggressive chemical environments | 1000°F | Maximum corrosion resistance |
| PVC / CPVC | Corrosive chemical tanks, plastic tank service | 210°F | Economical for corrosive service |
| Polypropylene | Aggressive acids and alkalis | 180°F | Plastic tank eductors |
