mud pump pulsation dampener charge pressure brands

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.

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.

A properly serviced pulsation dampener is critical for your mud pumps’ efficiency, safety, and performance. Unfortunately, there aren’t many resources available to educate personnel on executing safe and effective servicing procedures. Please review the following steps with your personnel for safe pulsation dampener maintenance.

Should you or your personnel have any questions regarding pulsation dampener maintenance, please don’t hesitate to ask. Sigma is more than happy to help you to ensure safe and proper care is being completed on your pulsation dampening equipment.

Our custom-designed systems will absorb excess energy pulsing through the pump and piping system by creating a low-pressure area to dampen the excess shocks and vibrations. Because a pulsation dampener regulates the release of energy, your system will be better protected and run more smoothly. After installing a pulsation dampener, customers notice that their system:

Premium is proud to offer a full-line of Pulsation Dampener Solutions. Our PD series dampeners are available in 5 ,10 & 20 gallon models and are rated for 5000 or 7500psi.

They are available in 1500 psi, 3000 psi, and 5000 psi ratings. Replacement diaphragms and parts are offered for 10 and 20 gallon, Mattco and Hydril pulsation dampeners. Also available are stabilizers, bottom plate gaskets, charging valves, pressure gauges (0-6000 psi), plates, screws, and lock washers.

A Pulsation Dampener is an inline dampening device used to smooth out pulsations in a pump’s output. They are used alongside a pump as a mounted accessory to help achieve certain flow rates for an application.  They can be used with a variety of Positive Displacement Pumps which typically generate a pulsed flow (Diaphragm Pumps, Peristaltic Pumps, Dosing Pumps, Piston Pumps etc)

Pulsation Dampeners are required in some process applications when the customer needs smooth flow into the next phase of the production line, for example, to get an accurate reading through a flow meter or to fill a hopper consistently. On the flip side, Dampeners can be used to reduce water hammer effects through pipework. Water hammer is where the pump causes the pipes to vibrate and potentially fail, a smooth flow from a Pulsation Dampener reduces this.

For example, Diaphragm Pumps inherently produce a very turbulent discharge flow meaning that in some instances a Pulsation Dampeners are required to give a smooth pulse-free flow.

In the Tapflo UK range, we focus on Pulsation Dampeners for Diaphragm and Peristaltic Pumps, although we can also supply them for other pump technologies.

The Active Pulsation Dampener works by supplying an equal pressure to the pulsation supplied by the pump. The Dampener supplies this pressure during the low-pressure points of the pump’s operation, as the pressure drops between pump strokes creating a pulsating flow. The pressure supplied by the dampener decreases pressure variations, therefore producing a steady flow from your Diaphragm Pump. You can see the pressure drops and Pulsation Dampener benefits in action in the diagram below.

Tapflo supplied a 2” Air Operated Diaphragm Pump to a bleach factory, the customer used the T400 PTT for a couple of days and then called us to explain that the bleach line, running along the roof of his production facility, was shaking. Due to the nature of the product being pumped health and safety on site could not allow this to continue.

To support our Peristaltic Pump customers, Tapflo offers an in-line Pulsation Dampener for our PT and PTL Series’. They can reduce the pulsation of your PT Pump by as much as 90% to reduce the vibration and water hammer effects on pipework. Another benefit of this accessory is its ability to be installed on-site horizontally or vertically for flexible installation.

The CAT Pumps 6018.800 Prrrrr-O-Lator pulsation dampener is ideal for use in pumping systems that require vibration, hammering, or pressure fluctuation reductions. It is rechargeable and can come pre-charged with Nitrogen at your specified PSI level. Please note the amount of pre-charge pressure you would like in your order comments.

This unit is compatible with non-continuous flow of rates up to 40 GPM at 3000 PSI. Please note that pressure capability is reduced as fluid temperature increases; when maximum operating temperatures of 180° F are reached, the 6018 Prrrrr-O-Lator may only be used on systems up to 2500 PSI.

Suction dampener is a very effective aid for improving suction performance and eliminating fluid pulsations in the suction line, which results in a smoother flow in the discharge line.

The mounting for KB-75 pulsation dampener (1) is a flange with R-39 seal washer. Before installing dampener, thoroughly clean ring groove and ring, and after setting dampener into place, tighten the nut (8) with 950-1265N.m (700-935ft.lbs) torque. Tighten nuts in a criss-cross order.

The discharge pulsation dampener is only allowed to charge nitrogen or air. No inflammable and explosive gases are allowed such as oxygen, hydrogen etc.
