Italian ATOS gear pump PFG-199 in stock
$425.71
When the Italian ATOS gear pump is working, the driving gear rotates along with the motor, driving the driven gear to rotate as well. As the meshing teeth on one side of the suction chamber gradually separate, the volume of the suction chamber increases, the pressure decreases, and the liquid in the suction pipe is drawn into the pump. The sucked liquid is then pushed into the discharge chamber by the gears in two paths within the gear grooves. After entering the discharge chamber, the liquid is compressed by the continuous meshing of the two gear teeth and flows from the discharge chamber into the discharge pipe. With the continuous rotation of the driving and driven gears, the pump can continuously draw in and discharge liquid.

ATOS gear pumps are a type of positive displacement pump. They consist of two gears, a pump body, and front and rear covers forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side increases, creating a vacuum that draws in liquid. Conversely, the volume of the space on the meshing side decreases, forcing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears. The pressure at the gear pump's outlet depends entirely on the resistance at the pump outlet.
The structure of the ATOS gear pump is very simple. Its most basic form consists of two gears of the same size meshing and rotating within a tightly fitted housing. The interior of this housing is shaped like an "8," with the two gears housed inside. The outer diameter and sides of the gears fit tightly against the housing. Material from the extruder enters the space between two gears at the inlet, filling it. As the gears rotate, the material moves along the housing and is finally discharged when the two gears mesh. Technically, a gear pump, also called a positive displacement device, acts like a piston in a cylinder. When one gear enters the fluid space of another, the liquid is mechanically squeezed out. Because liquid is incompressible, the liquid and the gears cannot occupy the same space simultaneously, thus the liquid is expelled. This phenomenon occurs continuously due to the constant meshing of the gears, providing a continuous discharge at the pump outlet; the discharge rate is the same per revolution. With the continuous rotation of the drive shaft, the pump continuously discharges fluid. The pump's flow rate is directly related to its rotational speed. In reality, there is a small amount of fluid loss within the pump, preventing it from reaching 100% efficiency. This is because the fluid is used to lubricate the bearings and gear sides, and the pump body cannot be perfectly flush, thus preventing 100% fluid discharge from the outlet. Therefore, a small amount of fluid loss is inevitable. However, the pump still operates well, achieving 93%–98% efficiency for most extruded materials. This type of pump is not significantly affected by fluids whose viscosity or density varies during the process. If a damper is present, such as a filter or restrictor on the discharge side, the pump will force the fluid through them. If this damper changes during operation—that is, if the filter becomes dirty or clogged, or the back pressure of the restrictor increases—the pump will still maintain a constant flow rate until it reaches the mechanical limit of the weakest component in the unit (usually equipped with a torque limiter).
The ATOS gear pump is a type of positive displacement pump, consisting of two gears, a pump body, and front and rear covers forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side increases, creating a vacuum that draws in liquid. Conversely, the volume of the space on the meshing side decreases, forcing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears. The discharge pressure of the gear pump depends heavily on the resistance at the pump outlet. A gear pump is a rotary pump that transports or pressurizes liquids by relying on the change and movement of the working volume formed between the pump cylinder and meshing gears. The structure of an external meshing double gear pump consists of a pair of meshing gears and a pump cylinder separating the suction chamber and the discharge chamber. As the gears rotate, the volume between the teeth at the point where the gear teeth disengage gradually increases, the pressure decreases, and liquid enters the space between the teeth under the pressure difference. With the rotation of the gears, the liquid between each tooth is carried to the discharge chamber. At this point, the volume between the meshing teeth at the point of engagement gradually decreases, discharging the liquid. Gear pumps are suitable for transporting lubricating liquids that do not contain solid particles, are non-corrosive, and have a wide viscosity range. The pump's flow rate can reach 300 m³/h, and the pressure can reach 3 × 10⁷ Pa. It is commonly used as a hydraulic pump and for transporting various oils. Gear pumps have a simple and compact structure, are easy to manufacture and maintain, and have self-priming capability, but they experience large flow and pressure pulsations and are noisy. Gear pumps must be equipped with safety valves to prevent damage to the pump or prime mover caused by the outlet pressure exceeding permissible levels due to reasons such as discharge pipe blockage.
ATOS gear pumps are driven by an independent motor, effectively blocking upstream pressure pulsations and flow fluctuations. Pressure pulsations at the gear pump outlet can be controlled to within 1%. Using a gear pump in an extrusion line can increase flow rate, reduce material shearing and residence time in the extruder, lower extrusion temperature and pressure pulsations, thereby improving productivity and product quality.
