Product Description
The ANSI Chemical Process Pump is an ASME B73.1 standard end-suction centrifugal pump designed for general chemical process service in North American market applications. Its standardized dimensions ensure interchangeability with other ANSI pumps, while the back-pull-out design allows maintenance without piping removal. The pump handles flow rates from 3.6 to 540 m³/h at heads to 125 m and temperatures from -80°C to +180°C, with material options including cast iron, 316SS, duplex, and Hastelloy. Suitable for chemical transfer, petrochemical, and general industrial processing.
- Hydrostatic pressure test at 1.5× rated pressure
- Performance test at multiple operating points
- Dimensional inspection against ANSI B73.1 standards
- Material test reports (MTR) for wetted parts
- Final vibration and noise testing
Applications
The ANSI Chemical Process Pump is widely used in general chemical processing, pharmaceutical manufacturing, food & beverage, water treatment, and general industrial fluid transfer. It handles corrosive and non-corrosive fluids in a wide range of process industries.
- Chemical processing and manufacturing
- Pharmaceutical and fine chemical production

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
