PS: The pulsation dampener assembly we manufactured, could 100% interchangeable with the pulsation dampener of BOMCO/EMSCO/NOV/Hydril.

Installation position:Air chamber is installed at one end of the discharge pipe in the hydraulic end

Function:play a role of stabilizing the pressure and pressure compensation.

Working pressure: The working pressure of normal mud pump is 5000PSI, some high pressure mud pumps is 7500PSI.

1.Disassembling and assembling air bag must first relief.

2.F500/F800 mud pump using KB45 air chamber, F1000/1300/1600 mud pump using air chamber KB75.

3. Air chamber play an important role in drilling to reduce the fluctuations and stable pressure ,so in drilling production, maintaining the normal operation of the air bag is very important .

The maintenance of the air bag

(1). Air bag inflator pressure is 30% of designed pump pressure, the general pressure is 4~6MPa , the best pressure is 4.5MPa

(2). Mud pump at the normal working hours, the air bag cutoff valve is closed to protect gauges
