Regarding the selection of pumps
Thread Content
Hello everyone. In chemical synthesis processes where layering occurs, if pumps are used for transfer, the liquid flow rate becomes very low toward the end of the layering process. What kind of pump is suitable in such cases – a pump that can handle low flow rates or prevent damage when operating without any liquid flow?
It depends on how small it is; in the case of centrifugal pumps, backflow control can be implemented
Idle operation is already deadly; as for the low flow rate, could you provide detailed parameters?
Regarding borrowing a building: what data is needed to create a selection diagram for chemical processing equipment? For example, if I want to draw a diagram of this device, how do I find out its length, width, and height? The other required parameters cannot be found either; what should I do?
There are air-carrying magnetic pumps. It depends on your specific parameters though
Basically, use the same pump as before; only the seal requires a double-end design……
The outlet is connected to the return flow, and the mechanical seal is a double-faced type equipped with cooling water.
For applications requiring a low volumetric flow rate, positive displacement pumps can be chosen; there are many types available, such as diaphragm pumps and magnetic drive pumps, among others
