Positive Displacement Rotary Gear Pump
PA200S 2″ Stainless Steel Rotary Gear Pump
PDF · 1.7 MB
Overview
The PA200S is a 2″ port positive displacement rotary gear pump with a stainless steel housing and nitrile gears. It handles chemical transfer, corrosive fluids and food-grade duty at up to 69 GPM and 100 PSI, and is fully rebuildable in the field with standard hand tools.
The 2″ platform suits lower-volume metering and transfer where the 3″ PA300S would be oversized. For background on the pumping principle, see what a rotary gear pump is.
