Positive Displacement Pumps

FBF ITALIA positive displacement pumps are structurally very similar to the high-pressure homogenizers and manufactured to the same high quality standards. From the outside, the positive displacement pump differs from the homogenizer, because they lack the homogenization unit.
For Products Containing ParticlesThese pumps are mainly used for the positive-displacement pumping of products that contain particles, such as pieces of tomato, vegetable or fruit in soups, yoghurts, jams, etc ... even in the presence of particularly high counter-pressures (typically 50 bar or higher).The construction of the positive-displacement pumps is much the same as the homogenizers, except for the compression head which is equipped with special pneumatically controlled valve groups. These valves are equipped with actuators, which are controlled by an electronic angular positioner to assure perfect functioning of each valve. The angular positioner allows the opening and closing phases of each individual group of valves to be independently adjusted. The ability of the pump to operate at low speeds, combined with the specially designed passages in the pneumatic controlled valves, gives low velocities and very gentle handling; maintaining the specific characteristics of the most delicate of products.
