Electric piston pumps

摘要

This firm has developed a technologically advanced design for its electric top-hend-drive pumps to make servicing and repair easier in difficult locations. "The Anchor Electric's positive-displacement piston pumps put the electric motor and controls outside of the well, tank or sump, not down with the liquid being pumped," it's reported. Inlet clogging is eliminated, and servicing is performed safely and easily above the wellhead.
