The control of fluid dynamics is essential to ensure efficient, ,reliable and 
safe operation of pumping systems. A pump puts fluid in motion by adding energy 
to it. This kinetic energy, observed as pressure, is carried in the fluid and slowly 
lost to friction in the piping system. Uncontrolled fluid in motion can physically 
destroy the pump, piping, valves, meters and other system components.  
Positive displacement pumps create destructive pulsation and hydraulic 
shock due to the reciprocating nature of their stroking action, potentially damaging 
piping and system components. Pulsation Dampeners and Surge Suppressors 
remove virtually all system shock, enhancing the performance and reliability of 
fluid flow. Function: 
 Protect pumps, piping, valves, fittings, meters and in-line instrumentation 
from damaging pulsations, cavitation, thermal expansion, hydraulic shock and 
water hammer. 
 Prevent destructive pressure surges caused by pump startup and shutdown. 
 Prevent hydraulic shock resulting from emergency valve closure and other 
equipment shutdown. 
 Prevent agitation, foaming, splashing and degradation of product. 
 Ensure accuracy, longevity and repeatability of flow meters and pressure 
gauges. 
 Ensure a smooth steady flow in metering and chemical injection 
processes. 
 Ensure uniform and continuous application in spraying and coating 
processes. 
 Ensure proper measurement, flow and filling applications of food and 
pharmaceutical products. 
 Ensure consistent flow when dosing, blending or proportioning process 
additives Ensure a smooth transfer of viscous or abrasive fluids. 
Surge suppressor is a one commonly used solution for controlling  hydraulic 
shocksurge suppressor. This device is similar in construction to a pulsation 
dampener but sized and installed differently. The surge suppressor acts as a 
reservoir or accumulator to absorb and release fluid as needed. By doing so, it 
controls the rate of velocity change to a level slow enough to prevent water 
hammer. 
Three guidelines must be followed when using surge suppressors to prevent 
or minimize water hammer:   
 The device must be located in the correct area.  
 It must be sized properly to accumulate the correct amount of liquid.  
 It must be pre-charged with nitrogen to provide the proper shock control.  
Positive displacement pumps contain an inlet valve that alternately opens 
and closes, creating an acceleration and deceleration of fluid into the pump. Inlet 
 
163 
Stabilizers minimize these pressure fluctuations and acceleration head losses by 
preventing fluid column separation at the pump's inlet. Function: 
 Protect pumps, valves, diaphragms and pistons from excess stress and 
strain. 
 Protect inlet system components from vibration and fatigue. 
 Prevent premature system component failure and cavitation. 
 Prevent gauge damage due to vibration. 
 Ensure steady inlet flow conditions to extend pump diaphragm life. 
 Ensure complete chamber fill to maximize component service life. 
 Ensure accuracy of inlet side gauges. 
Without proper protection, process fluids regularly contaminate and damage 
in-line instrumentation. The strength and durability of Diaphragm Seals 
protect and isolate all forms of system instrumentation from the hazards of 
corrosive process fluids. Function: 
 Protect gauges and other pressure instrumentation from process fluid 
contamination and corrosion. 
 Prevent erratic pressure surges and clogging due to solids in process fluids. 
 Protect gauges from freezing and slurries. 
 Ensure gauge and switch accuracy. 
 Ensure accurate and consistent readings with corrosive or solids-laden fluids. 
Diaphragm pressure relief valves are designed to continuously regulate fluid 
flow to protect pumping systems from over-pressure damage caused by defective 
equipment or a blockage in the pump system line. 
Diaphragm back pressure valves enhance system performance by applying a 
continuous back pressure to the system pump. Eliminating fluctuations in 
downstream pressure prevents siphoning and eliminates varying dosage rates, and 
the continuous back pressure ensures proper check valve operation in metering 
pumps when system pressure is too low. 
Diaphragm failure in air operated diaphragm pumps allows process fluid to 
escape through the pump's air exhaust port. Unmonitored, the spill can result in 
significant expense to your company due to lost product, hazardous material 
cleanup, EPA reporting and system downtime. Leak Containment System prevents 
hazardous and costly spills by capturing the expelled process fluid and 
automatically shutting down the pump. 
Leak Containment System attaches directly to the exhaust of an air operated 
diaphragm pump. When pump diaphragms fail, Leak Containment System captures 
dangerous and/or expensive process fluid in an internal receptacle while raising a 
float switch to automatically shut down the pump. 
Leak Containment System can also be configured to sound a warning alarm 
and/or initiate a backup pump switchover. 
Every fluid system is different and many can be complicated and the goal 
was to provide useful information on design criteria for efficient and effective 
liquid handling systems.
