ARO 66605J-344 PTFE Double Diaphragm Pump, 13 GPM, 100 PSI

ARO 66605J-344 PTFE double diaphragm pump is a positive displacement pump that employs two sets of flexible membranes to move fluids, ensuring unidirectional fluid flow through the chambers. It is used in the chemical processing, pharmaceutical, food & beverage production and water treatment industries.

Working Mechanism:

• Air-operated diaphragm pumps separate the liquid chamber from the air chamber.
• Inlet and outlet air valves manage compressed air flow. At rest, the inlet valve is open, and the outlet valve is closed.
• To start the pump, compressed air enters the air chamber behind one diaphragm, causing it to flex inward, creating a vacuum that draws liquid in through the inlet check valve.
• As one diaphragm pulls liquid in, the opposite diaphragm pushes it out through the outlet check valve, producing a pulsating liquid flow.
• After the first diaphragm's stroke, air valves switch; the inlet closes, and the outlet opens, directing air to the second diaphragm.
• This process repeats, with the second diaphragm drawing in liquid and the first expelling it, maintaining a continuous flow.
• The dual diaphragm design ensures balanced, symmetrical pumping action, reducing stress on components for smooth, consistent flow.

Features:

• It features polypropylene housing for lightweight and chemical resistance.
• This double diaphragm pump has a PTFE valve for chemical resistance, ensuring reliability and longevity when pumping aggressive media.
• It is equipped with a ball valve effective for providing a secure seal and consistent flow rates.
• This double diaphragm pump offers a multiport manifold connection for easy integration of plumbing configurations.

Frequently Asked Questions:
