Pump medium replacement
Thread Content
This post was last edited by sxf1028102800 on 2017-5-21 20:42. I have an acid water pump installed; it’s no longer in use. Can it be converted into a gasoline pump to transport gasoline? Will the pump get empty? Please discuss topic 2, thank you, extra points
Firstly, the actual head of the pump varies depending on the medium used; secondly, is it safe to transport gasoline?
The parameters of different pumps vary
A change in density affects the operating head, but since I’ve never worked with gasoline as a medium, I think it must be quite dangerous. Is it risky for the pump to overheat after being used for a long time? Acid water pumps don’t seem to have any means of cooling the water
Most gasoline pumps are positive-displacement types, right? For centrifugal pumps, if friction occurs, it’s hard to ensure safety; a special design is necessary. It is unusable simply from a security perspective.
I also think that one should not consider only the changes in the density of the conveying medium; safety performance must also be taken into account. This constitutes a change to the process. Someone posted a thread today – problems arising from technical modifications are very common and quite troublesome
It will work as long as the head is sufficient; generally, centrifugal pumps are no problem!
It depends on the designed head and net positive suction head of this pump; it will be sufficient if it can meet the requirements for transporting gasoline at that operating pressure
Based on the design head and net positive suction head
The actual head of different pumps varies; is it safe to transport gasoline?
First, it is necessary to determine whether the pump is of explosion-proof type, and then consider the issue of the net positive suction head at the pump inlet.
