If you’re running any of these pump types, your system needs the protection of a pulsation dampener.
The right dampener:
- Reduces pressure spikes
- Stabilizes flow and measurements
- Extends the life of piping and equipment
Reciprocating pumps don’t fail because they pulsate. Systems fail when pulsation isn’t managed.

A dual‑pump process line was seeing persistent pulsation, unstable pressure, and vibration.
A site review found two configuration problems:
1. One dampener was serving both pumps
2. The dampener was installed far beyond the effective 10‑diameter distance
Fix:
- Relocated the existing dampener to the proper zone
- Added a second dampener s... (read more)

Your pump system is a crucial part of your operations. So when it breaks, everything stops.

A broken pump system is a big problem - costing time and money to repair. Depending on your project, it can be a safety hazard for your employees and community as well.

Pump systems break for a variety of reasons, but... (read more)

Pump failure is not an option.

You know that. We know that. But do you know how to catch the subtle symptoms of impending pump system failure?

Increased vibration or heat levels, changes in sound, uneven flow readings, and leaks signify emerging issues. Catching these early warnings allows maintenance teams to diagnose and correct problems through proactive maintenance befo... (read more)

Pulsation dampeners are vessels filled with compressed gas and process fluid, separated most often by a flexible bladder or diaphragm. The vessel is pre-charged with gas at a calculated value below the average system pressure before liquids are introduced.

Once the pumping system starts, fluid will enter the vessel and deform the bladder until the gas and fluid pressures equalize.... (read more)

Stop Diaphragm Failures Before They Start: How Inlet Stabilizers for AODD Pumps Improve Reliability

Frequent diaphragm failures can cripple plant operations and drive up maintenance costs. For facilities relying on Air-Operated Double Diaphragm (AODD) pumps, these issues often stem from one root cause: unstable inlet conditions. Installing an inlet stabilizer for AODD pump systems... (read more)

Matters for Fluid Control Systems

Good fluid handling equipment is a must for manufacturing facilities and processing plants. Whether you’re keeping a treatment facility online or driving throughput in a chemical reactor loop, the integrity of your pulsation dampeners, surge suppressors, and valves determines how long production stays up and how quickly it comes back if some...

Transient events (also referred to as “surge” or “water hammer”) occur in all fluid pump systems, the magnitude of which is determined by changes in fluid velocity, fluid density, pressure wave speed, and elevation changes. They can happen during pump start-up or shut-down and rapid opening/closing of valves. Transient events can cause catastrophic system damage s... (read more)

The amount of energy used by a positive displacement pump is proportional to the pump’s differential pressure. The higher the pressure added by the pump, the harder the pump is working. Reciprocating pumps accelerate the mass of fluid in the discharge line with each discharge stroke, which results in pressure spikes. A pulsation dampener reduces pressure amplitude by accumulating a... (read more)

Both surge and pulsation in a fluid processing system are the result of uncontrolled pressure waves caused by an abrupt change in fluid velocity. Fluid contained in an enclosed piping system has a physical volume and, therefore, its mass can be calculated. We can then determine acceleration forces needed to move that mass. Once in motion, the mass will stay in motion as long as enough fo... (read more)

SENTINEL Injection Quills are designed to safely and efficiently disperse chemicals into process pipelines. Chemicals are injected directly and evenly into the center of the process flow away from the pipe wall and where flow velocity is highest. This direct injection into the center of the flow avoids chemical contact with pipe walls and ensures more even mixing with the process fluid.... (read more)

Pressure Relief Valves—also called safety valves, bypass valves, pump relief valves, or pump safety valves—protect pumps, systems, and tanks from excessive pressure. Prevent damage, reduce the risk of cavitation, and increase personnel wellbeing with this essential safety component. (read more)

Installed at the pump’s inlet, an inlet stabilizer acts as an accumulator to store fluid and release it back into the line as needed. Virtually all acceleration head loss is eliminated because the pump draws fluid from the dampener and not the pipeline, avoiding the risk of cavitation and ensuring complete chamber fill on each inlet stroke of the pump.
