External Gear Pump (FTNX and FTBX)
Fluid Tech Systems offers “ROTOFLUID” External Gear Pump Model FTNX / FTBX, a high-performance positive displacement pump designed for handling viscous liquids in demanding industrial applications. This advanced series is an upgraded version of FTRN/FTRB models, offering higher pressure capability and improved efficiency.
The pump features double helical gears and hardened ground shafts, ensuring smooth operation with minimal vibration and extended service life. Designed for both flange and foot mounting, it offers flexible installation across various systems.
Model FTNX is equipped with precision needle roller bearings for continuous duty and handling low viscosity fluids, while Model FTBX uses bush bearings suitable for lubricating viscous liquids and intermittent duty operations.
