Fluid End Parts
A pulsation dampener is a vital accessory installed on the discharge (or sometimes suction) line of mud pumps in drilling systems. Its core function is to reduce the pulsations produced by the reciprocating motion of the pump (e.g., triplex, duplex), thereby smoothing fluid flow and stabilizing pressure.
Product Description
A pulsation dampener is a vital accessory installed on the discharge (or sometimes suction) line of mud pumps in drilling systems. Its core function is to reduce the pulsations produced by the reciprocating motion of the pump (e.g., triplex, duplex), thereby smoothing fluid flow and stabilizing pressure.
Working Principle
Inside its cylindrical chamber resides a flexible bladder or diaphragm, pre-charged with gas (like nitrogen). When the pump generates a high-pressure spike, it compresses the bladder, momentarily absorbing the excess energy.
As pressure falls, the bladder releases the stored fluid back into the line, ensuring a more even and consistent flow.
Product Parameters
Dampener Type, Design Features & Best Use Cases
Bladder / Diaphragm: Most common; gas-separated fluid housing. Ideal for discharge lines.
Pressure Vessel: Compact, no moving parts-suitable for very high pressure applications, but less effective overall.
Suction vs. Discharge: Offers flexibility in mitigating pulsations on both sides of the pump.
Typical designs include:
Body, cover, bladder/diaphragm, pre-charge valve
Pressure gauge, bleed valve, check or relief valve
Suitable for mud pumps across a broad range of models.
Main Technical Parameters
Pressure Rating: Up to 5,000-7,500 psi (depending on model, e.g., KB20 etc.)
Fluid Compatibility: Standard mud; oil-based mud resistant bladder options
Models Available: KB10, KB20, KB45, KB75, PD-45, PD-55, etc.
Components Included: Bladder/diaphragm, pressure gauge, bleed valve, housing
Maintenance: Field replaceable bladder; easy pre-charge procedure
Product Advantages
Reduces Wear & Tear
Minimizes stress and fatigue on downstream components such as liners, valves, pipes, and fittings. By minimizing pulsations in system components such as regulators, solenoids, sensors, etc., the pump will reduce wear and extend service life.
Enhances Drilling Efficiency
Consistent pressure and flow lead to smoother operations and potentially improved rate of penetration.
Decreases Noise & Vibration
Dampens pulsations to create a quieter, safer work environment.
Prevents Pressure Spikes
Mitigates sudden surges, akin to water hammer-protecting your system's integrity and Power Zone Equipment integrity.
Quick Responsiveness
Acts like a shock absorber-instantaneously responding to pressure fluctuations to stabilize the system.
Structural Features of Spherical Pulsation Dampener
A Pulsation Damper and Air Bag is an accumulator with a fixed precharge that absorbs system shocks while minimizing pulsations, pipe vibrations, water hammer and pressure fluctuations.
Pulsation dampers are attached directly to the discharge manifold or installed directly downstream of the pump.
We offer a wide range of Drilling and Production Spherical Pulsation Damper and Air Bag.
Volume sizes range from 10 gallons to 20 gallons and pressure ranges from 3000 psi to 7500 psi.
The body of the spherical pulsation damper is constructed from a one-piece steel forging, eliminating the possibility of weld fatigue failure.
They are interchangeable with Hydril Series "K" dampers, Emsco Series "PD" dampers and Bomco Series "KB" dampers.
One-piece forged valve body (no circumferential welds), making the valve body stronger and the inner surface smoother.
The inner surface is machined to facilitate diaphragm movement.
Field-replaceable top and bottom panels.
Base plate connection to meet customer application requirements.
Diaphragms are available in a variety of materials to suit application requirements.
Company Strengths
Reliable Oilfield Construction: Bladders made of oil-based mud-resistant urethane (e.g., Patriot™), ensuring long service life.
API / ASME Certified: Available as ASME-U stamped or built to rigorous API standards for onshore and offshore use.
Field-Serviceable Design: Easy pre-charge, bladder maintenance, and part replacement reduced downtime.
Wide Application: Compatible with major mud pump makes and models-ideal for both new installations and retrofits.
Advanced Materials: High-quality bladder materials (NBR, HNBR, FKM) tailored to varying fluid chemistries and thermal conditions.
