Nomad Energy Gusher Pump
The Nomad Energy Gusher Pump is one example of a technologically advanced product brought to you by researchers at Nomad. The pump’s design not only ensures an efficient transfer of fluid, but it also performs in the difficult conditions that cause most conventional pumps to fail (sand, scale, extreme loads).
The Gusher Pump is a modified version of the Downstroke Pump. It still has a plunger that protrudes from the top of the barrel. It uses the same principle, that of taking the stored energy of the lifted rod string and displacing the fluid in the pump barrel on the down stroke, pushing the fluid up to the surface. The difference is in using oversized valves and a plunger with a larger I.D. These changes make the Gusher Pump the best choice in rod pumps for heavy oil and high-volume pumping in water floods.
In standard rod pumps, the ball-and-seat valves have less than 25 percent of the flow area when compared to the bore size of the pump. Compare a 2¼ conventional pump and the 2¼ Gusher Pump: The bore of a 2¼ pump is 3.976 square inches. Standard 2¼ valve seats have a flow area of .885 square inches. The plunger and traveling valve of the Gusher Pump have 2.761 square inches of flow area. This gives the Gusher Pump over three times the flow area when compared to conventional pumps of the same size.

| Two sizes of Gusher Pumps are currently available, the 2¼ bore which will run in 5½ casing with 3½ tubing and the 1¾ bore which will run in 4½ casing with 2½ tubing. Other sizes can be specially designed depending on casing size. | |
