What’s the quickies way to fix a leaking compatible Markem Imaje ENM5629 pressure pump? Contact your supplier for a new replacement? Yes this could do, but while you are waiting for a replacement, the quickies way to fix the leaking pressure pump is to do it yourself.
We have all the pumps tested before delivery, however, sometimes I do get feedback about pump leakage. The problem often lies in bad sealing between the nut and the pump, therefore air goes in the pump and results to the ink leakage.
To fix this problem, we could use PTFE tape to wrap up the nut a little, and then put it back to the pump. With the PTFFE tape to increase the contact area, it can prevent air goes in the pump.
