Why Choose Our Chemical Centrifugal Pumps
Centrifugal Hydraulic Efficiency
Closed-type impeller with optimized vane geometry achieves peak efficiency 75-82%, reducing power consumption and operating cost compared to generic chemical pumps.
316L Stainless Standard
Standard 316L stainless steel wetted parts with low carbon content (≤0.03%) for improved intergranular corrosion resistance in chemical and pharmaceutical applications.
Mechanical Seal Versatility
Accommodates single spring, multi-spring, and cartridge mechanical seals from all major manufacturers, with quench and drain connections for hazardous or crystallizing fluids.
Compact Footprint
Close-coupled or long-coupled options with standardized baseplate, minimizing installation space and simplifying plant layout in modular process skids.

Selection Guide
✅ When to Choose This Pump
- General chemical transfer and circulation
- Acids, alkalis, and solvents at moderate temperatures
- ISO 2858 standard dimension interchangeability
- Plants requiring easy maintenance and spare parts
⚠️ When NOT to Choose
- Highly abrasive slurries (use slurry pump)
- Zero-leakage requirements for toxic fluids (use magnetic drive)
- High viscosity above 500 cP (use PD pump)
- Self-priming needs (use self-priming pump)
💡 Common Selection Mistakes
- Selecting wrong material for chloride-containing fluids
- Not accounting for viscosity derating
- Using standard seal for crystallizing fluids
- Ignoring suction piping design for low NPSH
