Mud Pump Pulsation Dampener is usually installed on the discharge line to reduce the fluctuation of pressure and displacement of the drilling mud pump.
Mud Pump Pulsation Dampener is a pneumatic device built into the outflow line of each UUD pump to dampen the pressure fluctuations resulting from the action of the pump. Although presented as a surge tank, this device is really a device that can be tuned to greatly diminish the output pulsations transmitted downstream from the mud pump. Unfortunately, the effectiveness of the pulsation dampener is a function of both output pump pressure and frequency of the pump pulsations.
The Pulsation Dampener 3375-0015-3 from the Hypro series assures smooth discharge from piston and plunger pumps. It also reduces peak loading on pump bearings and other internal parts. The Pulsation Dampener 3375-0015-3 extends the system life and minimizes maintenance costs.
As a general guideline, when using two cylinder or four cylinder piston pumps, the dampener charge should be approximantely 1/2 of the pump operating pressure. When using a three or six cylinder pump, te dampener charge should be approximately 2/3 of the pump operating pressure. This pump is rated for up to 1500 psi.

The reciprocating pump’s cylinders pull its fluids from the suction manifold. When the suction manifold has trouble refilling with fluid, the cylinders will take in vapor and create a void in the cylinder. This is called cavitation, and it produces a very adverse reaction that is transferred into the fluids.
When you install a suction stabilizer off the suction manifold port, this gives the manifold extra capacity to pull fluid from and eliminates the manifold’s opportunity to lack fluids, thus eliminating cavitation.
The second benefit the suction stabilizer offers is eliminating negative forces in the fluids produced by the pump’s valves opening and closing rapidly, creating a water hammer effect. The suction stabilizer’s compressible element is designed to absorb these energies and smooth out the fluid flow. This causes pump isolation or, in other words, the reciprocating pump is now isolated from the charge pump, and vice versa. The negative energies produced by the reciprocating pump never make it back to the charge pump, which extends the life of the pump expendables.
A properly serviced dampener is critical for the safety and performance of your mud pumps. See the following steps for safe pulsation dampener maintenance.
Pulsation problems often start on the suction side. Pulsation or cavitation is caused by the variation of fluid movement within a contained system. Since fluid is non-compressible, the energy produced by this pulsation or cavitation must be compensated for. With the introduction of pulsation equipment into a system this energy now has a place to expend itself. Without the pulsation equipment involved in your pumping system, the pulsation or cavitation that is present can lead to the following:
The installation of properly sized pulsation dampeners minimize vessel costs while protecting the pump and piping system and improving process efficiency and accuracy.
A pulsation dampener reduces or eliminates the variations in pressure and flow produced by reciprocating pumps. In many applications, low frequency pressure waves cause problems within a given piping system and/or process. Eccentric, cam-driven pumps are probably the most commonly applied for services that require pulsation dampening, e.g., metering pumps and reciprocating (power) pumps.
Pulsation dampeners are found in a variety of designs, but for our purposes we will focus on only gas-charged pulsation dampeners, which rely on a calculated volume of compressed gas, usually Nitrogen, which is alternately compressed and expanded in synchronization with the pump plunger to reduce or eliminate pressure pulsations. This gas volume is normally separated from the process fluid by a flexible membrane. Common membrane designs include elastomeric bladders, PTFE diaphragms, PTFE bellows or stainless steel bellows.
Pressure waves or pulses are a consequence of the alternating acceleration and deceleration of fluid velocity corresponding to the travel of the piston or plunger. The pattern and amplitude of these pulses varies with pump configuration, specifically the number and size of pistons, as well as fluid compressibility factors.
It is precisely the fluid volume above mean on the discharge cycle of each stroke, which induces these pressure pulsations into a piping system. The number of pistons offered by the pump-given that all are of identical diameter and equally phased-displace a known peak volume above mean. These constants may be influenced by fluid compressibility, but for the purpose of this explanation we’ll assume none at this point. A pulsation dampener absorbs only that portion of piston displacement above mean flow, and then stores it momentarily before discharging it during the portion of the cycle below mean flow (on the suction stroke).
A simplex pump displaces a volume of fluid above mean that is equal to about 60 percent of total displacement. A duplex pump displaces a lower fluid volume above mean, approximately half that of a simplex pump. Pumps of three or more pistons of equal diameter, stroke length and proportionally phased will always present a very small fluid volume above mean to the piping system. A triplex pump, for example, produces about a 4 percent peak, as long as fluid compressibility factors and pump efficiencies are not at issue.
These smaller fluid volumes are accounted for by the crank angle of each of the cylinders. Triplex pumps are offset by 120-deg. Quadruplex pumps are set apart at 90-deg offsets; quintuplex pumps are offset 72-deg, and so on. It is the resulting overlap in pulses that yield the smaller fluid volumes above mean.
Fluid velocity gradients follow the same mechanical velocity gradients of the eccentric cam that drives the piston(s). Halfway through the piston’s forward travel (discharge stroke), fluid velocity between the discharge check valve and the pulsation dampener begins to decay. The corresponding drop in pressure causes the membrane inside the dampener to expand since the internal gas pre-charge pressure is now higher than the line pressure. The (stored) fluid now being displaced by the pulsation dampener maintains velocity downstream of the dampener thereby reducing, if not eliminating, any downstream pulsations.
Note: A pulsation dampener removes pulses only from the line downstream of the dampener-not upstream. That’s why it’s always recommended that discharge dampeners be installed as close to pump discharge nozzles as possible. In an application of a dampener for suction stabilization (reduction of acceleration head losses), it is the velocity gradient between the supply vessel and the suction nozzle that is minimized.
Let’s begin by defining the pump details required to properly size a pulsation dampener. We will use these values in a sample calculation to help clarify the process.
The result of the previous calculation is then divided by a constant. As noted previously, the constant is a function of pump configuration. We use a conservative 1.5 for simplex pumps, 2 for duplex pumps, and 7 for triplex pumps. Remember-if the fluid is compressible, then the constant may have to be adjusted downward.
Fluid volumes above mean are well within the range of these constants. The fluid pulse above mean flow from a simplex pump, for example, is about 60 percent. When we divide full stroke displacement by 1.5 the result is a conservative 67 percent. The divisor 7 that we use for triplex pumps allows for a nominal 14 percent fluid volume above mean. While 14 percent is far above the actual 4 percent produced by triplex pumps, the higher volume is an allowance for practical reasons, specifically size and nozzle limits. Otherwise, the result would be a very small dampener relative to pump size.
Ranges of (process) temperature and pressure must be considered in any sizing calculations for pulsation dampeners. Compensations must be made for temperature variations, which affect gas density, and dynamic variations in system pressure, since sizing is based on a set pre-charge pressure.
The objective is to select a dampener that is adequately sized to handle a range of operating pressures with a single pre-charge pressure. Remember that the gas pre-charge pressure should always be based on the minimum operating pressure as the pulsation dampener will have no effect when the system pressure is below the pre-charge pressure.
Changes in ambient temperature can also influence gas density, but they’re generally disregarded for the purposes of pulsation dampener sizing. It is usually sufficient to make seasonal adjustments to pre-charge pressures, if necessary. Temperature and pressure calculations are recommended to be done using absolute values (Kelvin for temperature and BarA or PSIA for pressure).
Some fluids are highly compressible, such as cryogenics, olefins, liquefied gases, anhydrous ammonia, etc. In these instances, the benefit of lower pulsations from multiple piston pumps may be somewhat compromised. Fluid compression occurs during the leading edge of the (eccentric) crank angle. Given sufficient pressure and a high enough compressibility factor, there may be little or no overlap of pulses at all-in which case, adjustments have to be made and pulsation dampeners with larger gas volumes should be selected.
By installing a properly-sized pulsation dampener, users can reduce or eliminate pipe shake, vibration and noise. The result is a continuous flow of product which is required in many metering, mixing and spraying applications. Reduced pressure pulsations minimize long-term damage to instrumentation and pump components while improving the accuracy of many flowmeters and increasing pump efficiency.
Pulsation dampeners, also known as pulsation stabilizers, accumulators, arrestors and surge suppressors, are used to control and minimize the pulsations that result from a pressurized system’s pump stroking action. They increase system efficiency, performance, and pump life; decrease maintenance costs and down time; and protect pipes, meters, valves and instrumentation from pulsation, vibration, and hydraulic shock.
Most pulsation dampeners use a bladder, or bellows, to separate the process fluid from a compressible gas. During the pump’s discharge stroke, fluid pressure displaces the bladder or bellows and compresses the trapped gas. During the following cycle, the momentary interruption of fluid flow causes the compressed gas to expand, forcing the bladder or bellows to push the accumulated fluid back into the discharge line.
Generally, the majority of pump pulsation problems can be traced to and remedied on the suction side of a pump, even though some symptoms may show up on the discharge side In feeding the pump. It is extremely important to maintain a steady flow of fluid through the suction valves. Also, the fluid column must attach thoroughly to the face of the plunger to achieve complete cylinder fill on the suction stroke.

The pulsation stabilizer opening should be the same size as the opening on the side of the pump on which it will operate. This will guard against unwanted acceleration or deceleration of fluid as it passes between the pump and stabilizer. Always defer to the next larger size should an exact match not be available.
Before installing any pulsation stabilizer or discharge dampener, be sure to consider the makeup of the overall system. Be aware of system characteristics that could effect a stabilizer decision, such as other pumps running in line, upstream/downstream pressure considerations, fluid composition and temperature, such as crude oil, salt water or drilling mud, or multiple pumps on a common header.
NOTE: The stabilizer opening should be the same size as the pump opening or larger. flanged and threaded Sizes are available from 1" to 8" - depending on the Series.
