TopDrive Piston Pump

The patented Tough Seal by Q.E.D. Environmental Systems, Inc., is arguably the tightest sealing, safest, and most durable well seal available on the market today, providing unmatched rigidity and pipe support for pumping systems. With multiple sealing surfaces and unsurpassed clamping force, it is designed for all industry standard casing materials and commonly used wellhead, pump, and port configuration sizes.

Designed for reliable, high-performance pumping of almost any fluid under the most difficult operating conditions, TopDrive™ piston pumps allow for substantial flexibility in depth setting, drive, and flow options.

However, once in the field, technicians often find a need to change out the pumps for different applications factors—which sometimes necessitated removal of the seal. To solve this problem, Q.E.D. is introducing its new TopDrive Piston Pump system for landfills and other cleanup applications, featuring a versatile, easily modified drive assembly for pumping in a variety of situations.

The TopDrive Piston Pump system is QED’s most flexible option for landfill and cleanup applications. Its fully-interchangeable drive assembly allows for easy transitions between hand, solar, electric and top-drive pneumatic pumping without removing the well seal. This feature provides additional flexibility in pumping applications and the ability to pump most fluids under a wide range of operating conditions. The TopDrive Piston Pump can be paired with QED’s patented well seals, which provide unsurpassed rigidity and feature customizable port options to meet site-specific needs.

Advantages of topdrive piston pump system

There are no down-well pneumatic lines or electric motors, and the mechanism provides an optimal blend of power, reliability, and efficiency. A compact cylinder stroke results in greater efficiency and lower air or power consumption. Unique bearing design and durable seals deliver longer lifespan with simple installation and maintenance.


Other thoughtful design elements of the TopDrive Piston Pump include an interchangeable lower pump, which allows an upgrade to a higher flow rate and an adjustable drop assembly with 5 or 10-foot lengths, optimizing pump inlet depth. The pneumatic drive assembly features a linear bearing in addition to the internal pneumatic drive cylinder bearing, which is designed to increase the durability and lifespan of the pump. Finally, the TopDrive Piston Pump system includes a fully-customizable control panel designed to meet each customer’s needs.
