Pulsation Dampener Safety and Liquids Pulsation Dampener Safety and Liquids Pulsation Dampener Safety and Liquids

Compatibility with environment & pumped liquid

There are two primary dangers with incompatibility of pumped liquid or environment.
1. That liquids will escape: (see the PulseGuard safety difference below)
a). Seals and membranes can degrade before the first planned service date.
b). The velocity of the leak can cause physical injury or death.
c). The leakage could be of a toxic substance, or dangerous to the environment.
2. Vessel failure:
Corrosion can cause a violent burst, or over time corrosion stress cracking.

Commonly overlooked examples:
It can be safe to use 316/316L stainless steel for pipes carrying salt water and brine. This is because at flow velocities above 2 meters per second, the surface is "passivated".
-On the other hand -
Inside a filter or dampener , the velocity is lower, stainless can become like Swiss cheese, this is a danger with titanium modified stainless also. Cupro-nickel is a better choice. Where a PipeHugger, Liquid inside the bladder type of dampener is provided, the small end plug or "liquid contact part" could have been made from MONEL. There is a general believe that PTFE, DuPont TEFLON, & LDi FlexFlon, resist everything. Exceptions:- Ex/EG Nitric acid, Bromine -ides -ics, Chloros & Flouros -ides ICS
