Anyone ever seen a setup like this? A co-worker brought this in and havent a clue as to why they would put a 12v clutch on a pump except maybe to shut the pump off while engine is still running. As far as the other thing on there is that for a low pressure chemical pump setup?
That's exactly what it is...a pulse pump. Works the same way as the fuel pump on the engine. A diaphragm inside senses the pushes and pulls of the water going through the inlet valve, and converts it to a pumping action between the ports.
Here's the pump for sale...not any output info though. I have a relationship with my local Interlink dealer. I'll get ahold of him next week to see if he can shed some light on the specs.
