Cyclone E-Vac Pump System
The answer for pumping wells with EXTREME damaging solids

The Cyclone E-Vac Plunger system represents a true advancement in down-hole pump technology. Sand, grit, iron sulfide, and other fines which normally contaminate the produced oil and water can now quickly pass through the pump assembly. No longer are residual concentrations of these particulates allowed to collect between barrel and plunger.

Clearance between conventional pump plungers and barrels permit some fluid bypass, or slippage between these surfaces. Within this void space, sand, formation fines, and other particulates can accumulate. During the normal up-and-down motions of the plunger, these accumulations cause rapid wear, usually in the form of vertical scoring, to both the plunger and barrel surfaces. Moreover, frictional forces generated by these accumulations cause excessive stresses to be generated throughout the
pump and rod-string which often result in a stuck pump, automatic shut-down of the pumping unit, or a parted rod string.

Repairs necessitated by the above forms of damage, plus revenues lost during resulting downtime, cost the oil and gas industry tens of millions of dollars each year. By incorporating the Cyclone E-Vac Plunger system within the pump assembly, stuck plungers and premature wear of barrel and plunger surfaces can be eliminated. Costly well servicing and pump replacements can be reduced to a minimum.

How is this possible? During the down-stroke the Cyclone Seat Plug forces any entrained particulates collected within the space between barrel and plunger inward through the axial evacuation ports and into the center of the plunger. Here, they commingle with other fluids entering the pump and are displaced into the tubing. Throughout the up-stroke particulates are also collected within the E-Vac Radial Chamber, where, during the down-stroke, they are flushed upward and enter the tubing through the Cyclone Top Plunger Adapter.

Simultaneously with the above, the radial ported vane technology, incorporated within the Cyclone E-Vac Radial Chamber, causes the fluid/particulates to constantly rotate. This rotation permits the pump barrel and plunger to wear more evenly, resulting in longer pump life and a more cost efficient pump assembly. While the pump is not operational,
settling solids are redirected into the ID area of the plunger, reducing the possibility of stuck plungers and excessive barrel wear. This is done using the Radial Evacuation Ported Vane technology featured on the Cyclone E-Vac Plunger Adapter.

For best results, the complete Cyclone E-Vac Plunger System is recommended.
