In the world of advanced industry – from pharmaceuticals to semiconductors – vacuum technologies play a strategic role. The Hanbell pump range, distributed by Varisco & Co, represents excellence in the dry screw pump category.
The PD and PS series stand out for their high performance, long service life and reliability in continuous processes, even in corrosive environments or those containing aggressive chemical vapours.
PD SERIES: High capacity for heavy industry
Hanbell PD pumps are designed for environments where high pumping capacity is required. Some key features:
Flow rates up to 3052 m³/h, perfect for complex production plants
Final pressure up to 7.5 x 10⁻⁴ Torr
Water cooling and nitrogen purge system
Can be configured with an integrated booster to improve performance in the most demanding cycles
The larger sizes (such as the PD3052 or PD3012 models) are ideal for chemical, pharmaceutical and metallurgical production lines and vacuum evaporation applications.
PS SERIES: Compactness and versatility
Hanbell PS pumps offer a compact and modular solution, with flow rates from 80 to 1800 m³/h. Ideal for:
Systems with limited space
Scientific and R&D applications
Environments requiring quiet operation (<70 dB)
Models such as PS1302 or PS1802 offer an excellent power-to-size ratio and simplify integration into existing systems thanks to standard connections (NW, ISO) and global voltage range.
EFFICIENCY & REDUCED MAINTENANCE
Thanks to dry running technology, the entire process takes place without oil inside the pumping chamber. This:
Prevents contamination in sensitive processes
Significantly reduces maintenance
Increases the overall safety of the system
Hanbell Dry Screw pumps are equipped with water cooling and controlled N₂ flow to protect internal surfaces.
Reliability, efficiency, modularity and direct support in Italy. With Hanbell and Varisco & Co, the vacuum requirements of modern industries are met with concrete and high-performance solutions.
