Suction And Discharge Pulsation Stabilizer Dampeners

And Replacement Bladders And Parts - Repair Kits for Plunger And Piston Pump Systems

 

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.

SIZING INFORMATION

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. 

Pump Capacity:

Determine the amount of fluid a pump will be moving, at what speed, and at what pressure. Indicators: Number of plungers, Bore, Stroke Length, RPM Suction & Discharge Pressure

Fluid Type and Temperature:

Fluid that is pumped must be compatible with the internal cartridge material to ensure maximum usage/life of the internal bladder/cartridge.

Pump Opening Types and Sizes:

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.

Pump System:

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.

 

To size stabilizers, you will need:

     Pump Stroke Length

     Pump Connection Sizes and Types

     Suction and Discharge Pressures

     Fluid Type and Temperature

 

 

SUCTION							DISCHARGE
Pump Stroke Length	Cubic Inch Stabilizer						Pump Stroke Length	Cubic Inch Stabilizer
2-1.5" or shorter	100 cu. in.						2-1.5" or shorter	100 cu. in.
3" to 4"	300 cu. In.						3" to 4"	300 cu. In.
