Pulsation dampeners, also known as pulsation stabilizers, accumulators, arrestors, and surge suppressors, are used to control and minimize the pulsations that result from a pressurized system's pump stroking action. They increase system efficiency, performance, and pump life; decrease maintenance costs and downtime; and protect pipes, meters, valves, and instrumentation from pulsation, vibration, and hydraulic shock.

Pulsation dampener bladder assy.: Diaphragm (bladder), Stabilizer, plate, screw, lock washer.
HNBR rubber bladder is composed of a 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, and protect equipment from damage caused by severe vibration.
the product is also used as a stabilizer and vibration absorber for air pumps.
Filled with nitrogen in the air or inert gas, 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.
