Pulsation Dampers - Centrfugal Pumps - Standard Installations

How to ensure lowest in place cost and most performance by standard installation methods.

For Suction Side Pulsation, stopping low pressure waves from turning the supply line into a bubble mix and noise generator for preventing high frequency discharge pulsation, pipe or heat exchanger resonation.

INSTRUCTIONS:

2. Please move your mouse over the pump below that has your choice of damper type attached to it. 3. When you click on that picture, a table of those damper types will appear.

STANDARD INSTALLATIONS
How to ensure lowest in place cost and most performance by standard installation methods.
FOR SHOCK, "WATER" HAMMER, BACKFLOW CAVITY IMPLOSION ETC.
IT IS NOT POSSIBLE TO PRESELECT THE SOLUTION.
PLEASE PROVIDE INFORMATION BELOW.

Choosing Shock Stop Bottles, CHECK LIST:- "Water Hammer Alleviator Work Sheet"
Meeting the Safe Use Requirements of the EC Pressure Equipment Directive.

"Pump Start-Up Surge" Acceleration head to overcome the mass in the pipe system after the pump. Please at the least review 17, 6, 7, 10, 11, 15, 16, + 24, & 25. and answer:-
Pump Shut-Down "back Flow Bang" The mass and velocity of return, filling the void that was cause by continuing to flow away from the pump after it was stopped. Please at the least review 17, 6, 7, 10, 11, 15, 16, + 24, & 25 and answer:-
Fast Valve Closure - "Valve Slam Hammer" Deceleration of the mass of liquid in the pipe in a small amount of time. Please at the least review 17, 6, 7, 10, 11, 15, 16, + 24, & 25 and answer:-
Equipment recommendations we make for you, can not be better than the information you give to us.
Suitability for purpose recommendations made on the basis of data & calculations above are with the following normal responsibilities of the parties.
System Design	S.D. to consider	Pump Vendor	Bottle Peddler

Check What You Require* Establish the Allowable residual pressure amplitude: - (Shock rebound or "resonance" is sometimes referred to as "Pulsation")
Depending on materials and design temperature approx. 275 psi 19 Bar. Shock pressure max. ________	Stop Drive belt break-up, keep instant load changes less than 14%. ________	To stop tooth chatter wear, depending on machine inertia, keep pressure transients less than 12%. ________	To Stop premature Lift & "weeping", keep all pressure waves that are sustained for in excess of 40 ms below 9% less than static set pressure. __________	Prevent bust disk fatigue, by keeping repetitive spikes to less than + & - 4% of steady state pressure. ___________	Examples: 25 ft of 1" pipe with a 100 Hz frequency. Keep the shocks below 10 psi 6500 ft of 20" @ 0.5 Hz, keep below 30 psi. __________

PUMPS make FLOW, SYSTEMS cause PRESSURE, pressure pulsation is a system response, AND a system responsibility NOT a pump manufacturers liability.
