The HammerHead Pro is powered by compressed air. The air valves are designed so
that instrument quality air is not required. In fact, the HammerHead Pro can
handle water and oil in the air supply with no detrimental effect to the pump
performance.
The HammerHead Pro requires only three in-well line
connections: air supply, air exhaust and fluid discharge lines.
Fluids enter the pump through the inlet port positioned at the
bottom (bottom loader models) of the pump. As the fluid level rises in the body
of the pump, it displaces the dead air inside the pump, which is expelled
through the exhaust air valve. As the pump fills with liquid, the internal float
rises to the top of its stroke.
In this upper position, the float triggers a lever assembly,
which closes the air exhaust valve and opens the pressurized air inlet, allowing
air to enter and pressurize the pump.
With the air inlet valve open, air pressure builds up within
the pump body. This causes the fluid inlet check valve to close and forces the
fluid to be displaced up and out of the fluid discharge outlet valve.
As the fluid level falls, the float moves downward to the
bottom of its stroke.
In this lower position, the float triggers the lever assembly to close the air supply and open the air exhaust valve, and a new cycle
begins.
The HammerHead Pro does not bleed air and only consumes air on
demand during the discharge cycle. Thus, the HammerHead Pro is very air
efficient.
The gravity feed and the air displacement pumping action of
the HammerHead Pro does not create an emulsion of the contaminant in the water.
The pump can be installed in non-pressurized wells, wells with vacuum or
positive pressure.
