Martin Lorenz replaced his Speedivac vacuum pump a few years ago. He still has the old pump and is sure that the old one could still work.
The equipment amounts to 2 identical pumps which he ganged together to make a more powerful combined pump.
Images are attached here (note the red trolley is not included). As you can see it is no longer 'plug and play' and needs attention.
If you are interested in this pump, please get in touch with Martin, email email@example.com.
If you are coming along to the OSG AGM tomorrow, Martin will be there and could potentially bring the pump along to be viewed.
