The shock absorber protects the system from damaging blows of pressure and will increase the life of pressure gauges, meters and other devices in the discharge pipe. The size of the piston and the speed of the pump can play an important factor in the decision to use or not a shock absorber. The SIAM impulse pulsation damper reduces the pulsation of the discharge pressure, above 75% and offers a wide capacity range in terms of flow rates and pressures. We have a wide variety of shock absorbers.
