Pad Ball Plungers

The useful range of the Pad/Ball Plunger lies between the speed of the Shuttle Plunger and the sealing efficiency of the Disc Plunger. The Pad/Ball Plunger is very similar to the Shuttle Plunger but with a better seal against gas/liquid slippage. The Pad/Ball Plunger has all of the familiar moving parts of a standard, non-bypass  plunger and is therefore subject to the mis-treatment of high speed, hard running. It is used in low gas to liquid ratio wells that don’t have the bottom hole pressure required to run the more efficient Disc Plunger.
