Pfeiffer Vacuum+Fab Solutions launches SplitFlow 350 turbopump

Pfeiffer Vacuum+Fab Solutions has added the SplitFlow 350 to its turbomolecular vacuum pump portfolio in Asslar, Germany. The new model is designed for high vacuum systems with limited space and aims to combine higher pumping speed, lower power use and longer service life.

Why it matters: - The SplitFlow 350 is aimed at high vacuum systems where space is tight, including mass spectrometers. - Pfeiffer Vacuum+Fab Solutions is positioning the pump as a way to reduce the need for multiple turbopumps in a single system. - The model is designed to cut maintenance needs and support longer operating intervals, including up to five years without maintenance.

What happened: - Pfeiffer Vacuum+Fab Solutions launched the SplitFlow 350 turbomolecular vacuum pump in Asslar, Germany, on September 16, 2026. - The company expanded its turbomolecular vacuum pump portfolio with the new SplitFlow 350. - The pump combines high pumping speed with low power consumption.

The details: - The SplitFlow series uses multiple stages separated by rotor stacks. - Each stage increases the vacuum level, which can eliminate the need for multiple turbopumps. - The SplitFlow 350 includes an integrated sensor system that continuously measures rotor temperature. - The sensor system keeps the pump within its operating range to help prevent overheating and protect critical components. - The sensor system makes the turbopump intrinsically safe while supporting consistent performance and long-term reliability. - The SplitFlow 350 uses a hybrid bearing system that combines a ball bearing and a permanent magnetic bearing. - The permanent magnetic bearing stabilizes and balances the rotors without physical contact, which reduces wear inside the vacuum pump. - A newly developed high-performance lubricant is used for the ceramic ball bearing. - The lubricant offers improved aging resistance, optimized lubrication properties, high temperature stability and low outgassing. - An operating fluid reservoir continuously supplies lubricant to the ball bearings. - The reservoir helps reduce wear and maintain efficient operation. - The design is intended to make the SplitFlow 350 more cost-effective to maintain.

Between the lines: - Pfeiffer is emphasizing reliability, compact design and lower lifecycle cost rather than only raw pump performance. - The combination of sensor-based temperature control, hybrid bearings and upgraded lubricant suggests the product is targeted at demanding applications where downtime is expensive.

What's next: - Pfeiffer will likely market the SplitFlow 350 to users of compact high vacuum systems that need fewer components and longer service intervals. - The company did not provide pricing or availability details in the release.

The bottom line: - The SplitFlow 350 broadens Pfeiffer Vacuum+Fab Solutions' turbopump lineup with a compact model built for efficiency, safety and lower maintenance.
