Featuring a field serviceable pneumatic top-head drive motor that's easy to repair, the Vector piston pump design is ideal for landfill leachate, gas condensate recovery, and gas-well dewatering applications, as well as side slope risers and horizontal wells. Because the driver air never contacts the liquid being pumped, it eliminates fugitive exhaust emission and associated odor problems. A fluidic switch controls pump speed, reducing the risks of overpumping, silting, and clogging. The weather-resistant pump's speed control mufflers are located on the driver's side for easy adjustment and maintenance. Blackhawk Technology Co. www.blackhawkco.com.
