LEYBA

Robust and reliable oil-sealed rotary vane vacuum pumps

A robust vacuum solution for a broad range of requirements

The LEYBA LB series are a range of robust and compact single-stage, oil sealed rotary vane vacuum pumps. These pumps are designed and ideal for modern industrial applications that require rough, reliable vacuum supply. The high pumping speeds, low noise and vibration levels and high reliability offers reliable performance with low costs of ownership.

This air-cooled pump with its ease of service ensures minimum maintenance and hence leads to allow overall life cycle cost. These “Made in India” vacuum pumps are an ideal solution to suit a broad range of requirements.
