3 Verdergear R Series Internal Rotary Gear Pumps The Verdergear range of pumps offers an excellent solution for many difficult fluid transfer applications. As with all Verder pumps, build quality is assured with a two year warranty. The range of Verdergear R series internal gear pumps use a positive displacement principle. The capacity is directly proportional to the rotation speed and virtually independent of the pressure. The R series is designed to give a smooth, non-pulsating flow. The R series internal gear pumps are used for fluids of any viscosity, such as solvents (1 cst) or chocolate (max 100,000 cst). The special design also makes the R series pumps suitable for lubricating and non-lubricating fluid and for liquids with some solids. Features and advantages Self-priming Can handle viscous liquids Smooth non-pulsating flow Constant capacity Durable and robust build-quality for a long service life Verdergear internal gear pumps are being used in a wide range of industrial areas: Paints & Detergent Dosing and transfer of paints and lacquers, dosing of additives and pigments Food Pumping of chocolate, syrup, icing Chemical Pumping of resin, hardeners, acids, lyes and solvents Pharmaceutical & Bodycare Transport of solutions, dyes, fragrances and perfumes Verdergear Internal Rotary Gear Pumps 3

4 1 2 3 Working Principle Verdergear internal gear pumps use a self-priming positive displacement rotary working principle. Two gears generate the flow - The Rotor (1) and the Idler (2). The Rotor drives the internal idler. As the gears rotate, liquid is drawn into the spaces by the crescent (3) and smoothly transported towards the discharge port, where the gears mesh, closing the free space and expelling the fluid. The result is a constant, smooth flow with no pulsation.
