QBK-50 PVDF DN50 88GPM Pneumatic Diaphragm Pump
QBK-50 PVDF DN50 88GPM Pneumatic Diaphragm Pump is a corrosion resistant pumping solution designed for demanding industrial fluid transfer applications. We went with a tough PVDF casting for the main housing block because standard plastics just can't stand up to hot acids, nasty solvents, or high-purity chemical lines over long shifts. It connects up to a 2-inch (DN50) line size and pushes out a steady 88 GPM flow capacity, which hits a highly practical sweet spot for running busy pharmaceutical lines, emptying out chemical treatment sumps, or managing specialized industrial loops.The main win with this setup is that it draws its power strictly from your shop's compressed air lines. Cutting out the electrical components completely means you don't have to fiddle with wiring codes or worry about short circuits in damp, splash-heavy bays.
