PVDF Drum Pump Tubes

PVDF pump tubes for concentrated acids and alkalis that attack polypropylene: concentrated sulfuric acid, hydrochloric acid, sodium hypochlorite, and similar aggressive media. PVDF also takes higher temperatures than PP, with media temperatures up to 212 F. Tubes come sealless (MSL) or with a mechanical seal (MMS) in 27, 39, and 47 inch immersion lengths. The wetted path is engineered for chemical duty: Hastelloy C drive shaft, ETFE impeller, and in sealless form no seals in contact with the medium at all. If you are unsure whether PP or PVDF is right for your application, send us the chemical, concentration, and temperature through our contact form and we will confirm the material; the price difference is small compared to a failed tube.
