These sliding-vane pumps are alignment-free
The GNX Series sliding vane pumps (photo) are said to be the industry’s first alignment-free, reduced-speed pumps for use in both portable and stationary applications. The design eliminates the couplings between the gearbox and the pump and motor by rigidly connecting them in alignment with a C-face (or similar) motor on both the high-speed and low-speed sides of the pump. The result is a pump that will not need to be realigned either at initial installation or following a maintenance procedure. These pumps are suitable for chemical-transfer applications because they are more efficient than competitive technologies, providing high-level performance, high suction lift and line-stripping capabilities with low maintenance and life cycle costs, says the manufacturer. — Blackmer, Grand Rapids, Mich.
