electric water pump

I've been running a bosch pump on my car for a while now and its cooled great. I got it off a lightning heat exchanger and use the 3/4 hose to a Y block with 2 #8 hoses going to the block. the other day I ran up on an even smaller little pump from a Mercedes called an auxiliary water pump. I didn't expect it to pump enough being so small but it moves as much or more water than the other bigger pump. my car cools easy with the alky injection but I have no doubt this pump would cool a gas engine. its about the smallest pump I think you could possibly find so I thought i'd share.......  
this is the pump....

Looks like a nitrous Solenoid almost its so small

Dam I can't even see it ... What happens when you old

Thx lee

Its surprising how well this thing moves water.I figured the dragster guys would like the room and weight savings. This particular pump looks a little pricey but a friend of mine has a few of these new for $100 shipped.

I can text you a closer pic.....

What years and models of Mercedes are these on?

I take it the housing is plastic ??

Do you have any idea of the amp draw? Looks like a great idea.

The housing is plastic but this pump being made as auxiliary water pump leads me to think it'll stand the conditions. I think its for several models from late 80's to mid 90's.I did a little research on them trying to find gph and such but couldn't find anything. I know bosch makes lots of different shapes and sizes.
