The Pfeiffer Duo 125 (3-Phase Motor) is a dual-stage rotary vane pump incorporating a pumping speed of 120 cubic meters per hour (m^3/h).
DuoLine rotary vane pumps are ideally suited to cover applications in the low-to-medium vacuum range with pressures of up to 20^(-3) mbar. Our DuoLine vacuum pumps offer reliable operation for critical industrial applications including drying processes, metallurgical processes, and resin potting and casting systems – serving either as a standalone pump or backing pump in our roots-pumping and turbo-pumping stations.
The use of a magnetic coupling minimizes maintenance requirements, contributing to considerable per-pump cost savings resulting from less-frequent maintenance intervals. The product likewise includes a temperature sensor (3TF) for enhanced protection.
