F 550 S is known as a progressive cavity or eccentric worm drive pump, best suited to handling medium to high viscosity liquids up to 80,000 mPas. The pump develops a smooth flow at a constant pressure, offering low shear, pulsation-free liquid transfer. The pump is portable, but can also be used in fixed installations. Very easy to disassemble for maintenance and cleaning, with few moving components.  F 550 S 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.
