ELECTRIC PUMPS
Blackhawk positive-displacement piston pumps feature an all-weather electric drive motor above the wellhead, connected with high-quality downhole components. The pumping action is similar to that of an oilfield pump jack.
How Electric Piston Pumps Work
Above the wellhead:
A drive motor is matched to one of three power sources — pneumatic, electric or solar. The motor pushes and pulls a durable, flexible drive rod connected to a reciprocating piston near the bottom of the well.
Our electric pumps are reciprocating rod, positive-displacement piston pumps powered by industrial-quality compressed air. The motor is at surface grade, above the wellhead for easy installation and maintenance. Power to the pump is direct from surface through the sucker-rod assembly. The fluid inlet is at the pump bottom intake and removes fluid to 0 submergence depth.

Low-flow pumping action pulls liquid from the well without disturbing the formation:
- The flexible fiberglass drive rod, enclosed in a riser-pipe cylinder, connects the motor to the piston in a pump barrel.
- As the motor pulls up the rod, the piston creates suction at pump intake.
- Liquid is pulled through a strainer into the foot valve.
- Stainless-steel balls in the reciprocating piston and foot valve open naturally to allow liquid into the piston, then close to prevent liquid from returning.
- The pumping action lifts liquid up the riser pipe with each stroke; the liquid exits a discharge tee above the wellhead.
