The Model VUP Unloader Pump mounts directly to the inlet separator, minimizing space requirements and eliminating the need for a barometric drop-leg. The Model VUP will operate against the vacuum and is self-priming, so no recirculation loop or controls are required to maintain NPSH. The Model VUP will even recover and self prime if the separator happens to run dry. Pump, motor, and drive are all mounted to a common base for easy installation and maintenance. The Model VUP pumps are available in cast iron or 316 stainless steel.
