Product introduction:

rubber bladder is composed of rubber pulsation bladder,rubber balance plate and pressure plate bolt, it can reduce the drilling pump pressure fluctuations of instantaneous displacement change;

Make the pump pressure smoothly, protect equipment from damage caused by severe vibration.

the product is also used as stabilizer and vibration absorber for air pump.

Filled with nitrogen in the air or inert gas, in the absence of them,air can replace.But oxygen or combustible gas is forbidden.

Inflation pressure is 20% ~ 30% of the maximum working pressure. The advanced filling pressure is 2.0-2.5 MPa.


Mainly applicable to 25 to 35 Mpa drilling, to meet the needs of high pressure jet drilling.


Above are our regular specification, any customizing request is also welcome.
