Selection of section pumps in the chemical industry! ! !
Thread Content
First, let me provide some background information: The feeding pump used for the storage tanks in a certain section of the workshop (which contain hydrochloric acid) was originally a rubber-lined pump or a plastic-lined pump; it was used for intermittent operations, and there were also instances of idling. Due to the high number of repairs required last year, it is now necessary to choose a new type of pump for this application. My question to all of you experts is: how should we select an appropriate pump for these conditions?
This isn’t a problem related to pump selection; it’s a management issue. Even the best equipment can get damaged as a result of improper operation
There is idling, and there’s nothing much that can be done about it. A fluorocarbon-lined material can be used for the hydrochloric acid pump, along with an anti-freeze protection device.
Provide medium temperature, flow rate, and head
If the pressure is not high and the temperature is not high, a plastic pump capable of running without load can be used
What is an anti-rotation protector? Could you please provide the model number? Thank you so much!
It must be the undercurrent overcurrent protector.
Medium: 30% hydrochloric acid, room temperature, flow rate of 18.5 cubic meters per hour, head of 30 meters. PS: The original glue feeding pump used was a 50KFJ-38
Consider consulting a pneumatic diaphragm pump
Different manufacturers use different methods to denote models, so it’s meaningless to tell you the model number. An import/export size of around 2 inches should suffice; the manufacturer doesn’t recommend any specific options, so you’ll need to consult them directly. If your budget is limited, you can opt for domestic products
