mud pump pulsation dampener charge pressure pricelist

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 multistage 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 advantage of the CFD System’s small size, durability, and performance is combined with 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 proves to be the authority on state-of-the-art advancements in pulsation control technologies.

All pulsation dampeners utilize one of two methods for mitigating energy produced by reciprocating pumps; compression or exchange. The traditional gas-charged dampeners use a compressible gas cushion, either by a gas over liquid or gas-filled diaphragms, bladders, or cartridge. As the reciprocating pump produces pressure spikes, the gas compresses, thus absorbing the pressure difference and smoothing the pumped media flow. For maintenance free pulsation dampeners, rely on energy exchange. There is a common misconception regarding maintenance free pulsation control devices that the pumped media is compressible enough to absorb the reciprocating pumps’ pressure spikes. This is not true. However, the maintenance free pulsation dampeners work by utilizing the kinetic energy exchange. This kinetic energy exchange can only happen if the pulsation dampener’s volume is large enough to dissipate enough energy to reduce the adverse effects caused by the reciprocating pump. This is why maintenance free pulsation devices require massive volumes to be effective. Sigma Drilling Technologies has developed a pulsation dampening system that utilizes both methods for reducing the harmful effects of positive displacement pumps, both compression and exchange.

The pulsation dampeners shall be installed properly to reduce the pressure fluctuation and smooth the liquid flow. In order to extend the lifespan of the air bag, it is highly recommended to maintain the suggested proportion of the pump pressure to the pre-charge pressure of the air bag for the pulsation dampeners. Generally, the pump pressure shall be 2/3 that of the discharge pressure and no more than 4.5MPa.

2. During maintenance, the pump pressure and the pressure inside the pulsation dampeners shall be zero. Since the residual pressure is generally small and can not be indicated on the pressure gauge, user shall confirm the pressure carefully to avoid accident caused by low pressure.

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.
