The COST €€ of Air Operated Double-Ended Diaphragm (A.O.D.D.) PUMPS with Various PULSEGUARD Dampers Saving 40%, AND having stable pressure for free, when flow smoothing systems with an AODD by avoiding single connection "Pulse Dampers" because they can not respond. An air operated double diaphragm pump damper discharges while the pump is reversing direction. The bigger the air supply to the pump, the shorter the reversal delay and so the smaller the damper needed for the pump. |

| 22 M3/Hr. (100 USGPM) heavy oxides slurry at only 1.5 meters / sec in a DN80mm line settles our and plugs the Damper / Accumulator. The need is for flow-through constant agitation & lower connection cost. 160 in3 pulse volume from diaphragm reversal & 1,000 in3 - 16Lt. Acc., only reduced spike 30% |

| 2 Ts and a flange were saved by using a accumulator safety block, to which the damper face "O" seals and which provides for bracket mounting. The straight line from pump to damper guts gave pressure peak clipping. 2" pipe gave 3M/s. velocity The 720 in3, 4 connection damper does more than the 16 Liter Accumulator; but as the path is not through the damper, stable pressure was not evident. |
