We supplies forged and casted steel pulsation dampeners which are inter-changeable and compatible with Hydril series "K" dampeners, Emsco series "PD" dampeners and Bomco series "KB" dampeners. These units are dependable and reliable with API connections

K-10,3000 psi/K-10,5000 psi/K-20, 5000 psi/K-20, 7500 psi

KB-45, 5000 psi/KB-75, 5000 psi

PD-45, 5000 psi/PD-55, 5000 psi


The Hydril K-P Series Pulsation Dampener/Surge Stabilizer should be mounted in the vertical position (refer to Figure 1-3 and 1-4 for mounting options) with the mating flange connection at the bottom. The discharge dampener should bemounted as close as possible to the discharge port of the pump. If possible, it is advantageous that the dampener be mounted in such a way that the fluid stream is directed towards the fluid opening (see Figures 1-3 and 1-4) for maximum performance.
1.1 Mounting
1.1.1 Install stud bolts in the replaceable bottom plate.
1.1.2 Position dampener on gasket and mating flange so that the space between flange and bottom connection is totally equal around the
1.1.3 Install one lubricated nut on each stud and tighten one turn at a time until dampener is firmly in place. Assure that space between dampener and flange is equal.
1.1.4 Cross tighten nuts to the proper torque. Refer to  bolting data in Section 3.2.
1.2 Precharging (NITROGEN ONLY)
The correct precharge is vital for maximizing efficiency of the pulsation dampener. Generally, precharge pressure is based on the average operating pressure of the system, but precharge can be affected by other system parameters; for example. the use of MWD tools. For these applications, consult qualified Hydril personnel for correct precharging instructions.


1.3 General Precharging Instructions
1.3.1 The charging valve and pressure gauge are located under the valve guard and are exposed by removing the valve guard.
1.3.2 Before precharging the dampener, make sure all cover stud nuts are tightened evenly andcharging valve and pressure gauge seal nuts are firmly seated on the dampener.
1.3.3 Precharging is accomplished by connecting one end of the charging hose assembly to a standard commercially available NITROGEN bottle
and the other end to the charging valve located at the top of the pulsation dampener (Refer to Figure 1-1).
1.3.4 Precharge from a standard commercially available nitrogen bottle equipped with apressure regulator.
1.3.5 For those applications where higher precharge pressures are required, a gas booster pump is available; for example, Haskell International Inc.
1.3.6 Open bottle regulator valve until recommended precharge pressure shows on regulator gauge.
