Frequently Asked Questions

What is an ARO pulsation dampener used for?

An ARO pulsation dampener smooths fluid flow in pumping systems by absorbing pressure spikes and vibrations. It protects downstream equipment, reduces pipe fatigue, and improves metering accuracy in industrial applications such as chemical transfer, water treatment, and oil and gas.

What are the specifications of the ARO SB20A-ASS-T pulsation dampener?

The ARO SB20A-ASS-T pulsation dampener features an aluminum housing with a PTFE diaphragm. It has a 2 in NPT inlet, 2 in NPT discharge, and a 3/4 in NPT air inlet. This model is designed for high-corrosion resistance and is compatible with ARO diaphragm pumps.

Where to buy an ARO pulsation dampener worldwide?

3G Electric supplies the ARO SB20A-ASS-T pulsation dampener to customers worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your site. Contact our team for a quote and lead time on this item.

How to install an ARO pulsation dampener?

Install the ARO pulsation dampener as close as possible to the pump discharge, using compatible pipe thread sealant on the 2 in NPT connections. Connect the 3/4 in NPT air inlet to a regulated compressed air supply. Pre-charge the dampener to 80% of system pressure before startup for optimal performance.
