KD
The KD series acid-alkali resistant vertical pump is a heavy-duty industrial pump optimized for high-demand nickel plating filtration and aggressive chemical transfer applications. Engineered with innovative structural design and premium corrosion-resistant materials, it delivers exceptional flow and head performance while maintaining long-term reliability in harsh operating environments. Its unique dry-run capability and robust construction make it the preferred choice for manufacturing facilities requiring continuous, low-maintenance fluid handling for critical process operations.
High Efficiency Centrifugal Design: Minimizes air entrainment and delivers industry-leading flow rates and head pressures, ideal for long-distance transfer and high-pressure filtration systems.
Innovative FRPP Motor Bracket: Replaces traditional cast iron brackets with FRPP construction, drastically reducing acid gas corrosion and lowering overall machine weight.
Advanced Self-Cooling Shaft Seal: The integrated Teflon bellow seal effectively isolates the motor from chemical vapors, extending motor and bearing service life by up to 3 times.
Broad Material Compatibility: Available in FRPP, CFRPP, CPVC, and PVDF materials to handle liquids with temperatures up to 90°C and specific gravities up to 1.4.
Modular Construction: All components are easily accessible for maintenance, reducing repair time and operational costs.
