Eccentric worm-drive pump F 550 TR is perfect for emptying IBC's and tanks that are not accessible from the top. Pumps thin to highly viscous, pasty, self-flowing liquids up to 80,000 mPas. The pump develops a smooth flow at a constant pressure, offering low shear, pulsation-free liquid transfer. Can be mounted on a trolley or baseplate for mobile or stationary use. Very easy to disassemble for maintenance and cleaning, with few moving components. F 550 TR can handle hard and soft solid particles up to 8 mm in diameter.  Fitted with bearing flange, it requires FLUX direct drive three-phase electric or FPM type compressed air motor.
