Suction Problems with High Pressure Systems 10,000 to 30,000 psi - Suction has to start with a jump (700 to 2000 Bar) The National Oilwell (O.W.E. co) well head test rig, (A) below, was redeployed to 11,500 psi methanol and inhibitor pumping, prove injection systems. the fast return / suction stroke of pump (B) prevented from fully filling. discharge began with a huge acceleration until plunger hit liquid sent shock into system causing: 1. The pressure set valve (C) was blasted off its seat. 2. The chart recorder (D) was ruptured. 3. The certified gauge (E) immediately lost calibration. A PipeGuard LP pulsation dampener Part number: PiG / 15i / 600p / 1/2x3x3/8NPT Just one of 1000 items off the shelf inventory Results from proper suction filling 1. A further 70% reduction in pulsation 2. A 225% increase in pumpable rate 3. One year before recalibration was required High speed pumping systems create the same suction problems as high pressure. An example is a direct motor driven three plunger 2500 psi wash pump. White Finger Vibration of the high pressure cleaning lance from pressure pulsation made it impossible for the operator to clean for more than 2 hours. After fitting the flow-thru PipeGuard pressure pulsation interceptor, the two hours waiting time per day for circulation to return to the hands was saved. The PipeGuard dampener paid for itself in two and a half days and pump life between service was tripled. For Suction: PiG-ss-LP/15i/600p/0.375x0.50x0.50 For Discharge: PiG-ss-HP/6i/300p/0.375xx 0.25
