Busch Huckepack RH0040

This used Busch Huckepack RH0040 is a Roots-type vacuum booster pump designed to be mounted directly onto a backing pump to significantly increase pumping speed and improve vacuum performance in the medium to high vacuum range. The Huckepack line is a familiar name in laboratory and industrial vacuum systems where a single backing pump alone cannot achieve the throughput needed for larger chambers or faster pump-down times. By combining a Roots blower stage with an existing rotary vane or dry pump, the RH0040 effectively multiplies the system's overall vacuum capacity. This booster design is especially useful in applications such as vacuum drying, freeze-drying, distillation, and other process work where both speed and depth of vacuum are important. The compact
