Moyno Inc. offers the Moyno 500 pump, 301 series progressing-cavity pumps for applications involving corrosive chemicals. This positive-displacement pump can handle a variety of applications from clean, clear liquids to abrasive fluids. The 301 series pumps have a reverse covered seal between the rotor and shaft to eliminate metal exposure to fluids. A cushion- and cradle-mounting eliminates excessive operating noise and provides mounting versatility to fit within a process system configuration. All Moyno 301 series pumps include a molded, elastomeric “wobble” stator that increases the compression fit with the rotor for greater volumetric efficiency.
