ARO 2 in. Stainless Steel Shock Blocker w/ PTFE Diaphragm

Pulsation dampeners reduce pressure fluctuation found in normal diaphragm and piston pump operation and can help eliminate material foaming, material pulsation, hydraulic shock or material splashing.

Diaphragm pumps of any type have at least two points in their cycle where they provide no pressure or flow to a process. The unwanted result of this pressure fluctuation can often be material foaming, material pulsation, hydraulic shock or material splashing. While traditional pulsation dampeners can help reduce unwanted pulsation and other problems, they also require operator intervention and adjustments.

Features

• Auto-Adjust Valve: Similar to ARO's patented Air Tamer design; automatically adjusts to fluid pressure to reduce pulsation
• Air Chamber: Large air chamber offers air support to the diaphragm during the pulsation process and smoothing of fluid pressure
• Diaphragm: Flexes as fluid pulses from the pump
• Large Fluid Section: Offers sensitivity for 2 in. diaphragm pump fluid volumes
• Bolted Fasteners: For leak-free integrity, similar design and characteristics which set ARO Diaphragm Pumps apart from the competition
