The pumps this a strange story!
I use Viscotec Progressing Cavity Pumps Which cost about 5.000$ each.
I need 2 since the doming application is a two component.
I found from ebay 5 for 50$ each (3 new 2 used).
I was Lucky!

Our system didn't require that precise of metering the auger or screw pump will give. We use a large pressure pot that holds a 5gal bucket of the adhesive. I needed to have a valve that was positive off without leakage, drips or strings. This fit the bill without complicating the mess with electronic drive circuity. Just a simple pneumatic micro-switch on a linear cam.
Here is a look at the Loctite metering valve we use. Last ones we purchased were $950usd or so with rebuilds/repair about 1/2 that. That looks cheap compared to those pumps! You did get lucky. Careful though, that ebay
Loctite 97113
