Pulsation Dampener Solutions

Using antiquated pulsation dampener technologies that cause more frustration, increase costs, and are more dangerous to operate isn’t rational when streamlining operations and improving performance is the wise way to manage. Sigma Drilling Technologies offers 21st-century solutions to old pulsation dampener problems to maximize performance and equipment’ return on investment.

CFD System

Charge Free Dampener

Charge Free Conversion Kit

Charge Free Dampening System™

A sophisticated multi-stage pulsation control system designed for maximum performance and cost savings.

What Is The Charge Free Dampening System™?

The Charge Free Dampening System™ solves the logistic concerns of cost, performance, size, weight, durability, and post dampener acoustic resonance.

The Charge Free Dampening System™ is the first and only complete dampening system designed for maximum performance and cost savings. With the highest pressure rating at 10,000 psi, the CFD System far surpasses any pulsation control equipment in the drilling market today. Sigma’s system utilizes both appendage and flow-through technologies and yet still maintains the most compact design.

This multi-stage system utilizes several of Sigma’s advanced products that are proven to maximize efficiencies and upgrade operations of any reciprocating pumping system by themselves.

By protectively coating both inside and outside the system’s Charge Free Stabilizer™ and the Charge Free Dampener™, the system is entirely corrosion-resistant. The Charge Free Dampening System™ is easily the most protected pulsation equipment available.

The CFD System’s advantage is its small size, durability, and performance, plus the fact the system requires no gas charging. The utilization of the Charge Free Conversion Kit® maximizes the dampening effects of the system without the need for nitrogen charging.

The Charge Free Dampening System™ is categorically the most sophisticated pulsation control available for your rigs’ pumping operations. With the introduction of the CFD System, Sigma Drilling Technologies once again proves to be the authority on state-of-the-art advancements in pulsation control technologies.

The Charge Free Dampening System

Why The CFD System?

What if almost all cavitation possibilities were eliminated? What if your mud pump was isolated entirely from “pump cross talk”? What if you had 10,000 PSI drilling capabilities? Can you imagine all of this in a cost-efficient, ultra-durable, compact designed, high-performance system with no gas charging needed?

The Charge Free Dampening System™ or CFD System is a complete multi-stage system designed to mitigate both low and high-frequency energies produced by the reciprocating pump.

The complete Charge Free Dampening System™ is on the leading edge with a growing list of advantages and benefits.

  • Performance consideration for both sides of the pump
  • Highest pressure rated drilling dampener
  • Smallest, lightest, and most versatile pump performance package on the market
  • Most durable drilling pulsation dampening system available
  • No nitrogen required on either side of the pump

The Charge Free Dampening System™ by Sigma is the only system on the market of its kind. Now your pumping operations will surpass all others and outperform your expectations.

Charge Free Dampener™

Smallest and lightest, 10000 psi, and no gas charging needed; this dampener surpasses all others and will outperform your expectations.

What Is The Charge Free Dampener?

The Charge Free Dampener™ solves the pulsation dampener industry problems of cost, performance, size, and weight.

The Sigma CFD does not use a bladder or gases. Preferably, it utilizes the state-of-the-art, benefit-abundant Charge Free Conversion Kit®. For optimal mitigation through the entire operating pressure band, the CFC Kits are designed to amplify energy exchange and compression through an extensive surface area of precisely tuned and arranged components.

The CFD is the highest pressure rated and has the smallest and lightest footprint of any modern drilling dampener. AT 10,000 psi, the CFD will be a valued piece of equipment now and through the next wave of operation pressure requirements.

Keeping the technology from becoming obsolete was the first step, but another significant CFD design parameter was focused on product longevity. For that reason, the entire Charge Free Dampener™ has been phosphate coated inside and out. Not only is manganese phosphate coating an excellent corrosion-resistant finish, but it makes an excellent primer for paint. The CFD fasteners are completely corrosion-resistant, and they are intentionally recessed into the cover to protect them from damage. Plus, with the CFD’s forged steel body design, all the grains in the steel are moving in the same direction, delivering a robust product.

Sigma Drilling Technologies Charge Free Pulsation Dampeners

Why The CFD?

What if you could have the smallest, lightest, and best performing dampener available without ever needing to charge with gas or re-design your rig? Can you imagine the possibilities?

The Charge Free Dampener™, or CFD, is another innovative solution from Sigma Drilling Technologies. This patent-pending design solves both traditional and maintenance free pulsation dampeners’ operational problems by being smaller, lighter, and eliminating the need for any gas charging or unreliable bladders. The CFD was designed to maximize the performance of Sigma’s Charge Free Conversion Kit®. The CFC Kit has revolutionized pulsation control, and the CFD takes absolute advantage. The Charge Free Dampener™ supersedes all other dampener options available, and its list of benefits far exceeds that of any other.

Charge Free Conversion Kit®

Convert your gas-charged dampener into a maintenance free unit. This exciting system will give you all the benefits of both pulsation solutions.

What Is The CFC Kit?

The CFC Kit solves the operational problems common to gas-filled bladders.

The Sigma D-CFC Kit does not use a bladder or gases. Preferably, it utilizes a molded basket containing a layered system of compression discs, each of which comprises four wedges.

The discs are specially molded to compress in a preset pressure range. The pumping fluid enters the basket and encases and interweaves through the network of compression discs. The system’s operating pressure is uniformly applied across the disc’s entire surface, causing the discs to compress under pressure load. The compression of the discs provides an attenuation of system-induced pressure spikes.

The compression discs are molded in several different pressure ranges. The basket contains a mix of layered discs, providing dampening capability across a wide range of operating pressures. Sigma can help custom tune a dampener device by providing a combination of pressure discs tailored to your needs.

The D-CFC Kit provides effective dampening across various pressures and operates reliably by eliminating dependence on gas-filled bladders.

Sigma V5 Charge Free Conversion Kit

Why The CFC Kit?

What if you could take all the benefits of both gas-charged and maintenance free dampener solutions and combine them into one solution? What would be the outcome?

Sigma Drilling Technologies’ discharge Charge Free Conversion Kit®, or D-CFC Kit, is a “fit and forget” solution. It is compatible with nearly all known gas-charged pulsation dampeners that are currently being used in drilling applications. The patented system will convert your current gas charge dampener into a maintenance free unit by utilizing proprietary, closed-cell rubber technology. This exciting system will give you all the benefits of both pulsation solutions.

  • Zero regular maintenance required
  • Significant performance gains from existing equipment
