INTENSIFIER PUMPS with PipeGuard LP - PiG-LP's
Application Story

PDF of this page
Suction Problems with High Pressure Sytems 10,000 to 30,000 psi
Suction has to start with a jump 700 to 2,000Bar

PROBLEM 1, 2, & 3. Below
The National Oilwell ("O.W.E.C.O.") well head test rig A below, was re-deployed to 11,500 psi methanol and INHIBITOR pumping, to prove injection ysstems. The fast return / suction stroke of pump B prevented the suction from fully filling. The discharge stroke began with a huge acceleration until the plunger hit the liquid and sent a shock intot he system.
1. The rpessure set valve C was blasted off its seat.
2. The chart recorder D was ruptured.
3. The certified gauge E immediately lost calibration.

ANSWER - H "PiG" PIPEGUARD - LP
US Pt. No. PigLP / 15i / 600p / 1/2" x 3/8" NPT/ -
Metric Pt.#- PigLP / 0.25 Lt. / 40 Br. / 1/2" x 3/8"
Just one of 1000 items "of fthe shelf" Inventory.

RESULTS FROM PROPER SUCTION FILLING:
1. 70% Reduction in pressure pulsation
2. 225% increase in pumpable rate.
3. A year before recalibration 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 - below.

WHITE FINGER
Vibration of the high pressure cleaning lance from pressure pulsation, made it imporssible for the operator to clean for more than 2 house.
After fitting the FLOW-THROUGH PipeGuard Pressure Pulsation Interceptor, the two hours waiting time per day, for circulation to return to the hands, was saved.
The PipeGuard damper paid for itslef in two and a half days.
AND: Pump life between service was tripled.

For Suction:
Pig/ss/LP/15i/600p/0.375" x 0.50" to pmp.
For Discharge:
Pig/ss/HP/6i/3000p/0.375" to pmp. x 0.25" out

Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
