Olympia Maximatic and the demise of the Fluid-o-Tech 110V pump
It seems that Fluid-o-Tech no longer produces a 110V/120V vibe pump. I have been modifying Olympia Maximatic's to use the ubiquitous Ulka pump.
Steps:
- Remove the old pump
- Remove the teflon line that delivers water from pump to the solenoid valve / HX.
- Remove the electrical block that plugs into the pump -- Install fast-on connectors to the hot and neutral wires no ground needed)
- Remove the elbow and check valve from the old pump and install on the Ulka.
- Use a 1/8" to 1/8" braided tube (repurposed Rancilio Silvia supply tube) to connect check valve to solenoid valve stem (potential to re-use the teflon tube here).
- Inserting the Ulka in the space is very tight. It will take some maneuvering to get it in correctly and hanging on the existing pump cradle.
- Use new silicone tube to supply water from reservoir to pump inlet.
