We specialize in the field repair of all types of pulsation dampener assemblies. We currently service the East Texas, North Louisiana , and Dallas - Forth Worth areas, with expansion planned for all productive markets. We have established ourselves as the company to call on when you need the absolute best in pulsation dampener repair.
We offer service on a single pump or fleet basis, with written reports of each rigs equipment and recommendations. We have the absolute best record for bladder life, and service availability with competitive pricing with a recent discount announcement of over 20% for 2009. An inspection consists of monitoring, adjusting pre-charge, inspection of gauges, charging valves, and visible leaks.
We NEVER use cheap or imported replacement bladders. We are distributors for two rubber manufacturers, that give us the ability to have the absolute best fitting, and longest lasting replacement rubbers.

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.
To achieve desired results in your pumping systems, we provide a full line of Pulsation Dampeners.
Reduce Maintenance and Operating Costs
• Extend valve, fitting, and gauge life
• Eliminate vibration that causes significant damage to
weld connections and support structures
• Improve metering and control instrument life span
• Eliminate wear-producing shock in bearings, packing,
seals, and other pump components
• Reduce down time required for part replacement
• Increase system capacity by safely permitting
increased flow velocity and operating pressures
• Improve accuracy of setting and measuring and
metering equipment
• Promote safety by preventing breakage and leaks in
systems carrying flammable or hazardous materials
