ARO PD15A-ASS-STT Diaphragm Pump Air Operated 1-1/2 Inch

ARO PD15A-ASS-STT double diaphragm pump transfers corrosive chemicals, viscous liquids, abrasive slurries and wastewater. It is ideal for chemical processing, wastewater treatment and mining.

Working Mechanism:

• ARO PD15A-ASS-STT double diaphragm pump operates via compressed air, which enters the pump's chambers, separated by PTFE diaphragms. As air enters one chamber, it flexes the diaphragm, creating suction in the fluid chamber and drawing fluid in through the intake connection. Simultaneously, the opposite diaphragm expels fluid out through the discharge connection. This alternating action generates a pulsating flow, regulated by PTFE ball valves to ensure one-way fluid movement.

Features:

• This double diaphragm pump features 316 stainless steel construction for durability and structural rigidity.
• It comes with a diaphragm made of PTFE for chemical resistance.
• This double diaphragm pump offers a maximum flow rate of 130 gallons per minute.
• It complies with ATEX, CE and NEC standards.

Frequently Asked Questions:

Q. How can pulsation be reduced?

A. There is usually some pulsation of discharge flow in air-operated diaphragm pumps which can cause excess movement. This can be reduced by using pulsation dampeners with a membrane with a cushion of compressible gas / air that flexes to absorb the pulse, allowing a laminar flow downstream of the dampener.

Q. Is this double diaphragm pump contamination-resistant?

A. Yes, this ARO diaphragm pump has a bolted, leak-free design to resist cross-contamination and ensure user safety.
