PD Plus Features & Benefits


Double Envelope Gas Service

In addition to the features shown on the single envelope series, the drive shaft is mechanically-sealed and the oil sumps are plugged to provide an even higher degree of leakage protection.

Single Envelope Gas Service

Vent openings are tapped and plugged to prevent gas leakage. These fittings can also accept an inert gas purge for positive containment of the process gas.


Heavy-duty models ranging from 3.25” to 12” gear diameter and 2.5” to 48” rotor length designed to handled your toughest operational requirements to exact specifications.


PD Plus blowers can be configured into a vacuum booster. Vacuum boosters are used to “supercharge” vacuum pumps to greatly extend pump performance. This creates faster pumping speeds and deeper vacuum levels.


Seal areas are vented to atmosphere to relieve process pressure against the internal lip seals, and to provide oil-free air.
