The cost of a screw pump (progressive cavity pump) varies widely depending on size, materials, flow rate, pressure rating, and application. Below is a general price range and factors affecting the cost:
| Type | Capacity (Flow Rate) | Pressure Range | Estimated Cost (USD) |
|---|---|---|---|
| Small Industrial | 1–20 GPM (4–75 LPM) | 50–150 PSI | $1,500 – $5,000 |
| Medium Industrial | 20–100 GPM (75–380 LPM) | 100–300 PSI | $5,000 – $15,000 |
| Large Industrial | 100–500 GPM (380–1,900 LPM) | 200–600 PSI | $15,000 – $50,000+ |
| Custom/High-Pressure | 500+ GPM | 600+ PSI | $50,000 – $200,000+ |
Small pumps (for low-flow applications) → $1,500–$5,000
Medium pumps (common in wastewater, food processing) → $5,000–$15,000
Large pumps (oil, mining, industrial) → $15,000–$50,000+
Standard cast iron / carbon steel → Lower cost ($2,000–$10,000)
Stainless steel (SS 304/316) → Higher corrosion resistance ($5,000–$20,000)
Exotic alloys (Hastelloy, titanium) → For extreme chemicals ($20,000–$100,000+)
Stator elastomer type (NBR, EPDM, PTFE) affects price.
Low-pressure pumps (<150 PSI) → Cheaper
High-pressure pumps (500+ PSI) → More expensive (stronger materials, reinforced design)
Budget brands (Chinese/Indian) → $1,500–$10,000
Mid-range (European/US brands like NETZSCH, Seepex) → $5,000–$50,000
High-end (custom-engineered solutions) → $50,000–$200,000+
Explosion-proof motor → +$2,000–$10,000
Variable speed drive (VFD) → +$1,000–$5,000
Heating/cooling jackets → +$1,500–$7,000
Maintenance: Stator replacement every 6–24 months ($500–$5,000 depending on size).
Energy Efficiency: Screw pumps are generally efficient but consume more power with high-viscosity fluids.
