ARO PD01P-HKS-KAA-A Compact Pneumatic Diaphragm Pump

The ARO PD01P-HKS-KAA-A is a compact 1/4-inch, non-metallic air-operated diaphragm pump from ARO’s Compact Series, designed for reliable chemical transfer in tight spaces. It pairs a polypropylene center section with a PVDF (Kynar) body and Santoprene-based check materials, delivering chemical compatibility and durable service in demanding environments. The pump uses 1/4-inch BSPP/NPT ports for versatile plumbing, enabling easy integration into existing lines. Capable of moving liquids at up to roughly 20 L/min (about 5.3 GPM), it provides a balanced blend of flow and portability, and its weight is approximately 1.76 kg, making it suitable for OEM applications and portable transfer tasks. Wetted parts include PVDF/Kynar materials, supporting resistance to a broad range of solvents and corrosives while maintaining a compact footprint. This model offers a compact, corrosion-resistant solution for process automation, chemical handling, and laboratory transfer tasks where space is at a premium and metal pumps are undesirable.
