Frequently Asked Questions

Chemical industry prioritizes corrosion resistance and leak prevention; semiconductor requires ultra-pure materials and zero contamination; wastewater focuses on solids handling and durability; food & beverage needs FDA-compliant materials and cleanability; electroplating requires acid/alkali resistance.

Determine required flow rate first, then match pump curve to ensure the operating point falls within the efficient range. Consider system head loss, pipe diameter, and whether flow needs to be constant or variable. Oversizing wastes energy; undersizing fails to meet demand.

Key factors: 1) Chemical compatibility of wetted materials, 2) Operating temperature and pressure, 3) Presence of abrasive particles, 4) Proper installation and alignment, 5) Regular maintenance, 6) Cavitation avoidance, 7) Motor operating conditions.

Pumps adapt via: 1) Casing and impeller designed for pressure ratings, 2) Mechanical seals rated for specific pressure ranges, 3) Variable speed motors to adjust pressure output, 4) Multi-stage designs for higher pressure applications.

At higher altitudes: 1) Reduced atmospheric pressure lowers NPSH available — select pumps with better NPSHr, 2) Self-priming height decreases, 3) Motor cooling efficiency drops due to thinner air — consider derating, 4) Verify motor performance at altitude.

Main applications include: chemical processing, electroplating, wastewater treatment, PCB manufacturing, semiconductor, pharmaceutical, food & beverage, and industrial filtration systems.

A corrosion-resistant pump is a fluid transfer device designed with specialized materials (PVDF, PP, stainless steel, etc.) to withstand aggressive chemical media, preventing degradation and ensuring long service life in corrosive environments.
