What’ll You Have? How About a Scotch & Solar?

Three solar panels mounted on yellow and black stands are positioned in an open grassy area. Near the setup, a top-head drive pump is connected with wiring and pipes that run to a central unit. The sky is partly cloudy with blue patches visible.

An Argument for the Most Versatile Combo in Environmental Pumping

It’s simple, dependable, cost-effective, portable, versatile, durable and moves virtually anything that flows. Three ingredients: 1) The “old-reliable” piston-pump downhole, 2) the top-head driver (with only four moving parts) and 3) the solar panel.

The combination is increasingly being used at landfills, toxic-remediation sites, biogas and pipeline condensate operations, coal-ash and coal-tar recovery zones, petrochemical plants, remote/closed sites and for other applications benefitting from low-flow, controlled pumping not served by trenched power.

Pumping Coal-Ash Leachate to Stay in Compliance

A solar panel is mounted on a metal frame in an open field with tall grass, connected to an electrical box and a cylindrical pipe below, resembling a top-head drive pump. A flag is attached to the top of the frame. The sky is partly cloudy with bright sunlight illuminating the scene.

Apollo Solar Pumps Operate at
Remote Sites, Without Trenched Power

Near coal-fired electric power plants across the U.S. lies the residue of burned bituminous. The EPA calls it Coal Combustion Residuals (CCRs) — a combination of powdery light ash, heavy bottom ash, boiler slag and flue-gas desulfurization material.

The residue is commonly known as coal ash. It is often buried at sites officially classified as solid-waste landfills.

As with all landfills, rainwater can infiltrate a site to create liquid leachate. Coal-ash fluid is clear but can contain salts, heavy metals and other toxic chemicals. Fugitive coal-ash leachate can threaten public health.

Positive-displacement solar piston units pump virtually anything that flows, including high temperature, viscous or foamy fluids at any pH; operate at any angle including horizontal; are unaffected by changes in positive or negative pressure; can run dry without harm;
