2'' EXP Non-Metallic Air Operated Diaphragm Pump
ARO® EXP air operated diaphragm pumps with bolted PVDF and conductive PVDF wetted parts offer best in class features when transferring corrosive and dangerous chemicals, including applications in explosion proof environments, such as ATEX – Group II 2GD X*.
Furthermore, in most cases, ARO® EXP pumps with PVDF or conductive PVDF (CPVDF) wetted parts offer a better alternative to diaphragm pump models that rely on machined polytetrafluoroethylene (PTFE) or conductive PTFE (CPTFE) construction:
•Lower Risk of Leakage: The robust bolted design of the non-metallic ARO® EXP PVDF pump offers better sealing compared to diaphragm pump construction technologies that rely on PTFE**.
1.PVDF and CPVDF offer better mechanical properties than PTFE and CPTFE given their chemical composition. This mechanical property delivers a more reliable sealing capability with respect to material cold flow or creep
2.PVDF has a better surface roughness than PTFE, resisting better to abrasion and various impacts.
•Lower purchase Cost: PVDF features a lower cost of raw materials and longer maintenance and pump replacement cycles than PTFE. Making it more affordable than machined PTFE diaphragm pumps or aftermarket PTFE coating options**.
•Safety and sustainability: Fewer leaks translate to higher safety due to lower exposure of personnel to chemicals, and a more sustainable solution thanks to fewer occurrences of chemical spills into the environment. Furthermore, longer pump replacement cycles help reduce plastic waste and increase product cost of ownership.
