Introduction
Why reciprocating pumps require pulsation dampeners:

• Early failure of plungers, valves, seats, springs, and packing
• Piping and connection fatigue
• Loss of pump efficiency
• Excessive downtime

These are the more common problems in the fluid ends and piping systems of reciprocating pumps that result in unnecessarily high maintenance costs as well as unsafe conditions. The cause? Pulsation.

What is Pulsation?

A pulsation (or pressure surge) is a variation in pressure within pumping systems caused by the inertia of the fluid column being accelerated and decelerated. The magnitude of these pressure surges depends upon the characteristic of each particular pumping system. The number of plungers (pistons), bore and stroke length, crank angle, and piping configuration are generally the more important factors to consider. Multiple pumps with common suction and/or discharge headers tend to experience additional problems with overlapping pressure surges and harmonic interference. Regardless of the magnitude, most positive
displacement pumps used in the industry today encounter pulsation.

Discharge

Difficult piping configurations on the discharge side, especially multiple pumps with a common header,
usually result in severe pulsations in the piping system. This also affects downstream components such as meters, gauges, valves, and the flowline itself. Discharge dampener absorbs and evens the flow from the pump with the same type of cartridge function as the suction stabilizer.
It also helps to eliminate harmonic interference in multiple pump/common discharge installations.

Solution

In addition to lower maintenance costs and reduced downtime due to system failure, the stabilized pumping system permits increased pump speeds and yields higher volumetric efficiencies.
