SW Series
SW Series Direct Coupled End Suction Centrifugal Pump
The FILIPUSI SW series is a high-efficiency, direct coupled (close-coupled) single-stage end suction centrifugal pump engineered for reliable fluid transfer in HVAC, cooling, and industrial applications. Featuring an optimized hydraulic design with a wide high-efficiency plateau, the SW series delivers exceptional energy savings in continuous-duty cooling and circulation systems.
Key Advantages
• High-Efficiency Hydraulic Design: Optimized volute and impeller geometry provides a wide efficiency plateau, reducing energy consumption in continuous-duty applications
• Close-Coupled Compact Design: Motor mounts directly to pump bracket, eliminating coupling alignment and saving 30% floor space
• Back Pull-Out Maintenance: Rotating assembly can be removed without disconnecting piping, reducing downtime by up to 60%
• Low Vibration & Noise: Dynamic shaft balancing and rigid baseplate ensure quiet operation (<75 dB)
• Multiple Material Options: Cast iron, ductile iron, bronze, SS304/316 for various fluid services
• VFD Compatible: Ready for variable frequency drive integration for precise flow control and energy savings
