Difficult Pumping Applications from
Blackhawk Environmental Company
Gentle Pumping Action Eliminates DNAPL Emulsification and
Pump Corrosion
BLACKHAWK ENVIRONMENTAL COMPANY’S Anchor Pump®,
positive displacement piston pump, effectively cleans up and
recovers Dense Non-Aqueous Phase Liquids (DNAPL). Typically
DNAPL is found in 20’ to 120’ deep wells with
DNAPL often residing in the bottom few feet or inches of the
well. These viscous, heavy, sticky and corrosive liquids are
difficult to successfully recover. Many types of pumps, including
“Pneumatic Passive Fill Air Displacement Pumps”
and “Electric Submersible Pumps” are used without
much success because they do not suck liquid from the bottom
of the well, corrode the pumps and emulsify the DNAPL, making
the product difficult to treat once recovered.
Blackhawk’s Anchor Pump effectively pumps viscous/sticky
liquids such as coal tar, creosote and other DNAPL products.
The Anchor Pump’s unique slow and gentle pump action
uses a very low recovery rate that eliminates product emulsification
and pump corrosion. The low flow rate accommodates the DNAPL’s
yield into the well and keeps from emulsifying the product.
In addition, the Anchor Pump draws product from the bottom
of the well.
The Anchor Pump is a plunger pump, with a reciprocation action,
that mechanically recovers fluid from the well bottom, independent
of the well’s liquid level, while maintaining a constant
flow recovery rate. It features a top head drive mechanical
oil well type sucker rod that effectively recovers all types
of DNAPL products. Its smooth controlled flow recovery has
the ability to tune the rate of the recovery to the yield
of the formation being pumped; preventing premature silting
or degradation of the recovery well.
The Anchor Pump’s deep recovery capabilities can produce
400 psi of pressure. Anchor Pump can be set for a flow range
of 0 to 11 US GPM. Anchor Pumps feature top head mechanical-drive
mechanisms and uncomplicated controls, making installation
and on-site maintenance easy - even under the toughest conditions.
The unit can be powered pneumatically, electrically or by
windmill.
Blackhawk Environmental Company provides pumping solutions
for the environmental, landfill, groundwater and industrial
markets. Blackhawk specializes in manufacturing quality pumps
and controls for demanding pumping applications.
