The flow rate range of melt pumps is quite extensive, and their specifications are typically expressed in terms of displacement per revolution, with units usually being cubic centimeters (cc) or grams per minute. Specifically, the flow rate range of melt pumps includes but is not limited to the following specifications:
Flow rate range expressed in displacement per revolution (cc):
Small specifications: 0.1cc, 0.5cc, 1cc, 2cc, 5cc, etc.
Medium specifications: 10cc, 20cc, 31.5cc, 50cc, 100cc, 150cc, 200cc, 315cc, 500cc, 800cc, 1200cc, etc.
Large specifications: 2500cc, 3200cc, 4000cc, 6100cc, 8500cc, 12000cc, 30000cc, etc.
Flow rate range expressed in grams per minute:
Generally, the flow rate range can be between 20 and 500 grams per minute, depending on the pump model and rotational speed.
The selection of the flow rate range for melt pumps depends on specific application scenarios and requirements. For example, in plastic extrusion processing, it may be necessary to choose a melt pump with a higher flow rate to handle large volumes of plastic materials; whereas in the manufacture of small batches or customized products, a melt pump with a lower flow rate may be required to meet precise conveyance requirements.
Additionally, the flow rate is influenced by factors such as the rotational speed, pressure, and viscosity of the melt pump. Therefore, when selecting a melt pump, multiple factors need to be considered comprehensively to ensure that the selected pump meets the specific application requirements.
