BFEqualizers® operate on the principle that volume is inverselyproportional to pressure (P1 V1=P2 V2). Compressed air or gas is intro-duced into the air chamber of the BF Equalizer® to a specified pressure.The gas is entrapped by the elastomeric bladder, which prevents contact between the process fluid and compressed gas. Without the bladder,the gas will dissolve into the fluid and cause product contamination. When a pulse is created, fluid enters the wetted chamber of the BFEqualizer®, displacing the bladder, compressing the gas and absorb-ing the shock. When the liquid pressure decreases, the gas expands,pushing the fluid back into the process line.

NEW ADDITIONS TO THE EQUALIZER ® FAMILY 

MANUAL ADJUSTMENTManual BF Equalizer® models are equipped with a self-relieving regulator. It requires a permanent supply of compressed air and allows for easy adjustment of internalair pressure. This model can be used on the suction ordischarge side of the pump. It is most effective when the airsupplied is 4–6 psig below pump head pressure.

 AUTOMATIC Automatic BF Equa lizer® models are equipped with an auto-matic valve on the air chamber. The Automatic BF Equalizer®model requires a permanent supply of compressed air andis self-adjusting to varying system pressure. It is used on thedischarge side of air-operated pumps in varying pressuresystems where manual adjustments are not feasible.
