Positive Displacement (PD) Pumps

Positive Displacement (PD) Pumps
Central Vacuum Pumps

Positive Displacement Vacuum Pumps are designed for long distance, high-volume material conveying.

Each model employs a powerful, rotating lobe-type blower, protected by a vacuum relief valve (factory-set to 12" Hg) and belt driven by a three-phase motor with magnetic starter and overload protection.  An integral pump protection filter is included.  All components are mounted on a rugged frame that houses an integral exhaust muffler.  An optional sound enclosure may be added to reduce noise.
