Introduction:
The Turbo-V pumps are designed to meet the most demanding needs of the market. They offer unmatched reliability, performance, and cleanliness.

The innovative MacroTorr pumps feature an award-winning, patented design that provides the highest speed/compression ratio performance in the smallest package. Since MacroTorr pumps can operate at high foreline pressures, they allow the use of diaphragm roughing pumps, providing a completely clean, oil-free pumping package.

Ceramic bearing pumps deliver long operating life. In fact, ceramic bearings provide reduced rolling friction, low stress, high thermal stability, and high elasticity module as compared to conventional stainless steel bearings. Proprietary ultra-low vapor pressure solid lubricant eliminates the need for routine maintenance and assures clean operation in case of misuse.

Designed to withstand heavy industrial use, Turbo-V pumps recover quickly from accidental air in-rushes. Corrosion resistant versions ensure safe operation in systems requiring handling of aggressive gases.
