The pumps are suitable for groundwater and surface remediation, recovery, landfill and petrochemical pumping. They can pump virtually any liquid, in environments from standard to extreme, including hot, harsh, solids-laden and winter cold, the company says. Blackhawk's Edge piston pump is suitable for groundwater and light remediation and landfill pumping. It is competitive with popular airlift models but has greater power and reliability. Model 101 pumps deeper than airlifts to 281 ft (85.6 m) with flow rates of 2 gpm (7.6 l/m) and model 102 pumps to 119 ft (36.2 m) with flows of 5 gpm (18.9 lpm). The Edge 102 pumps with increasingly positive flow comparisons versus airlifts beyond 60 ft (17 m) of head. The V-2 is a mid-range piston pump designed for remediation, recovery and landfill. The model 101 pumps to 555 ft (169 m) with flow rates of 2 gpm (7.6 lpm) and the model 102 pumps to 243 ft (74 m) with flows of 5 gpm (18.9 lpm), while the model 103 offers flows of 11 gpm (41.6 lpm) at depths to 84 ft (25.6 m). The Atlas 2.5 is a heavy-duty, powerful pump. The model 101 pumps to 813 ft (248 m) with flow rates of 2 gallons per minute (7.6 lpm), and the model 102 pumps to 359 ft (101 m) with flows of 5 gpm (18.9 lpm), while the model 103 offers flows of 11 gpm (41.6 lpm) at depths to 137 ft (41.8 m). The drivers and controls are above the wellhead, and the piston pumps require far less maintenance than airlifts, with no pump pulling and no pumps lost down the well. The can pump to well bottom with controlled draw down and no wasted head over pump, and can pump at any angle. There is less chance of bio growth and foaming due to no air-leachate contact.
