I did a similar thing. I'm using my Berkeley jet drive to power a water jet pack I built. Being that I'm in static mode the shaft seals started getting hot. I took the pump apart and made my own lantern ring that goes in place of the 2nd rope in the gland. I have an external pump pumping water into it through a hole i drilled over the lantern rings location. Solved my problem. I'm having a problem attaching a picture of it here because it keeps telling me it wants to resize the picture then I click OK and then it's gone. Oh well
