Aseptic centrifugal pump selection precautions

As the needs of our market and centrifugal pump technology, many centrifugal pump products have been elevated to a very high level, for example in the biopharmaceutical industry, in order to ensure a sterile environment, we must use some special equipment Operate. Aseptic centrifugal pump is born under such circumstances, then such a special product we need to choose how to deal with the product? Sterile Centrifugal Pump (1) Material characteristics such as working temperature, viscosity, density, whether there is particles and so on. (2) working environment, including altitude, operating hours, local electrical requirements. (3) The head is also called pressure loss. The calculation range is all the parts between the outlet end of the pump and the final water point. The required lift of the system is another important performance data of the pump, which is generally enlarged by 5% to 10% After the amount of lift to selection. (4) NPSHa NPSHa is calculated from all components before the inlet of the pump. The NPSHa of the system should be higher than the value of the NPSH of the pump to be able to operate normally. (5) The flow rate is one of the important performance data of the pump, which relates to the capacity and capacity of the whole plant. Process design to calculate the pump's normal, minimum and maximum three kinds of flow, pump, the maximum flow as the basis, taking into account the normal flow; in the absence of maximum flow, it is usually desirable 1.1 times the normal flow as the maximum flow. Hope that the above aseptic centrifugal pump selection precautions analysis, for the majority of users in the selection of aseptic centrifugal pump to provide help. In fact, many times, not the quality of the product is not good, but in the product selection, we ignore the precautions. People often emphasize measures suited to local conditions, only in the right place, to maximize the value of this sentence, the same applies to aseptic centrifugal pump.
