Diaphragm vs transfer pump

Dont know too much about them, dont use them
Seems to me that transfer pumps cannot handle bleach whereas diaphragm do or are chemical resistant, like the ones you guys use for soft wash.
Looking to see if i should get either for transferring bleach

Why would you spend a grand or so to transfer bleach just get a transfer pump they work fine

A transfer pump is about $40, and a 12v pump about a $100.
$1000 for a 12v pump?

Thought you ment the air difram pumps mb😂 id grab a 12v pump imho. Also some 12v pumps I have seen called transfer pumps.
