Synopsis overview

When the system has been designed then a pump can be chosen with characteristics that suit the system. That is the best way to avoid shock surge and pulsation.

Because flow is so slow, there is time to flow up, come to a stop ad flow back down a “T”. On the other hand, whatever the residual pressure pulsation level is, it may still shake the pipes.

Volume Accumulator





But the impact from the velocity of waves, does the damage fast.
Pulsation Dampener Intercepts Pressure Pulsation
Pressure in a fluid travels at Mach 1 (in air), in harder substances (liquid) is transferred at up to 4000 mph (140,000 cm/sec).
Mass of liquid in a pipe is transferred at not above 180 inches / second (460 cm/sec).
 

Pulsation and shock is common to all piping systems, it is only the pressure amplitude and frequency that changes
