Shielded scroll dry pump

Evp-pb series scroll dry pump is the next generation of completely oil-free dry scroll pump. Compared with the traditional scroll dry pump, evp-pb pump has stronger performance, higher pumping speed, lower limit pressure, lower power consumption and less noise. The gas ballast allows the pumping of condensing steam, including water, solvent, dilute acid and alkali. Evp-pb series scroll dry pump also adopts the end sealing technology, significantly extending the time interval of end sealing replacement. The integrated inverter drive with automatic voltage input sensing function provides overall optimized pumping performance, and evp-pb series scroll dry pump can be fully maintained on site.
