Centrifugal pump impellers come in three basic configurations. Closed impellers have two shrouds — one on each side of the vanes — creating enclosed flow passages with small internal clearances...
Fluimac Dragon Series
Mechanical Seal Centrifugal Pump
High-Flow Chemical Transfer With a Corrosion-Rated Seal
The Fluimac Dragon series pairs a solid PP or PVDF pump casing with a direct-drive electric motor for fast fluid transfer and drainage from 6 to 40 m³/h. The semi-opened impeller keeps pumping through dirty fluids with apparent viscosity up to 500 cps and small suspended solids. Sealing is handled by an externally mounted, internally pressurised mechanical seal with 100% virgin PTFE bellows — a mechanically driven design that prevents slippage on the shaft and resists extreme corrosion, rated to specific gravity 1.9.
PTFE-bellows mechanical seal — externally mounted, internally pressurised, with SiC/Carbon/FPM/SS304 faces for extreme corrosion resistance
Handles dirty fluids — semi-opened impeller continues pumping with viscosity up to 500 cps and small suspended solids
PP and PVDF construction — solid casing and impeller with EPDM or VITON O-rings for broad chemical compatibility
Seven sizes, 6–40 m³/h — DR006 through DR040 covering light transfer duty up to full process-scale flow
