EB Series Pulsation Dampener

Positive displacement pumps create destructive pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially causing damage to the piping and system components. EVOL bladder type pulsation dampener offers the most efficient solution to reduce or eliminate pressure variations and complete system shock on the pump discharge.

Bladder Type

This pulsation dampener works actively with either compressed air or gas, usually nitrogen and elastomeric bladder. The elastomeric bladder ensures no leakage of compressed air/gas into the process fluid, thereby enhancing the performance and ensure a steady process fluid flow in various applications including municipal, industry, sanitary and chemical transfer applications.
