A list of coolant pumps
This is a list of water pumps that may be useful in an EV swap.
Pierburg CWA Coolant Pumps
The Pierburg CWA Coolant Pumps (200/400) are well known in hot rod engine swaps as they are significant coolant pumps that have the ability to be PWM Controlled, however connecting the PWM pin to +12V permanently also gives 95% speed
Tesla Model S/X / Nissan Leaf Coolant Pump
Both the Model S and X use a very capable (but curiously unbranded) coolant pump. Internet research seems to indicate it may be made by VariMax, though there are so many Tesla part numbers it's hard to say which actual model it is.
The Nissan Leaf also uses this or a very similar pump.
Bosch PCE (VAG and others)
