Volumetric pumps are devices designed to move fluids by trapping a fixed amount of liquid and then forcing it into the discharge pipe. They operate based on the principle of displacement, ensuring a consistent flow rate regardless of pressure changes. Common types include gear pumps, diaphragm pumps, and piston pumps. These pumps are widely used in various industries, including chemical processing, food and beverage, and pharmaceuticals, due to their ability to handle precise volumes. Their design allows for efficient operation, making them suitable for applications requiring accurate dosing and flow control.
