Busch Labyrinth Sleeve Part# 322148036 – vacstellar

This Busch Labyrinth Sleeve (Part# 322148036) is a must-have. It is specifically designed for the Busch Mink MM1104BV and MM1114BV pump models.

this part has a special design. Inside, it features a “labyrinth” – a series of tiny grooves and channels. Think of it as a complex maze for air and particles to travel through.

This clever design creates a very effective seal without parts touching each other. It is a core technology that allows your pump to be “oil-free.”

In an oil-free vacuum pump, keeping oil out of the vacuum chamber is critical. This sleeve’s main job is to act as a barrier.

It minimizes the backflow of oil from the gear area into the clean vacuum side. This ensures the vacuum you create is completely free of oil contamination. It protects your process and your pump.
