Pump

Morning all,

How could I use this gadget as a pump by adjusting it on a tap?

Senior Technician did it last year but I can't make it work,

Big end bit at the top connects to a tap, run water through it, it comes out the small end and air is sucked in through the bit coming out of the side. The faster you run the tap, the faster the air is dragged in through the venturi effect. Once set up, I don't normally find they have many problems.
 
The top knurled part should attached to a water tap, the barbed nozzle on the side goes to whatever you're trying to pump air out off. Then turn on the tap, water flows through, comes out the bottom and also sucks air out.
