Slayer: Replacing Gear Pump

Watch a video to learn how to replace the gear pump on your Slayer 1-Group espresso machine.

If your Slayer 1-Group gear pump needs to be replaced we have a video here showing how to do that (password is "prebrew"). It is the fifth video on this page entitled "One Group Pump Replacement".

Before attempting this we recommend verifying the pump is the cause of any issues you are seeing happen with your machine. To verify whether or not the pump is causing any issues with your Slayer follow our pump pressure loss troubleshooting guide.
