Vector-Type Drive powers progressive cavity pumps.
August 18, 2009 -
Covering performance band of 0.08-4.7 gpm and pressures to 360 psi, Vector-Type Drive integrates progressive cavity pump with single reduction gear box, 4-pole TEFC inverter-rated ½ hp electric induction motor, and variable frequency drive in NEMA 4 enclosure. Integrated system offers speed range of 20-600 rpm. Featuring H-O-A switch with 10-turn potentiometer for manual control, drive will accept 4-20 mA process signal through standard ½ in. UNF-connector.

Integrated Vector-Type Pump Drive
New 10-page brochure details the new seepex integrated drive for its popular line of metering and general transfer progressive cavity pumps. The drive integrates the pumps with a single reduction gear box, a four-pole, TEFC, inverter-rated ½ HP electric induction motor and a "vector" type, variable frequency drive in a NEMA 4 enclosure. Because external or special fabricated control enclosures are not required for high pressure or run-dry protection, installation is no more complicated than a typical home stereo. The pump and drive combination can cover a performance band of 0.08 gph to 4.7 gpm and pressures to 360 psi. The effective speed range of the units is 20-600 rpm.
The unit operates from standard 1x120 VAC, 15 amp circuits with a 5-15p grounded plug. Unlike DC drives, this unit has excellent speed control, even in areas where input line voltages vary, such as agricultural or oil production fields, There is also no concern for contamination or maintenance caused by the wearing of commutator brushes. The drive has an H-O-A switch with a 10-turn potentiometer for manual control and will accept a 4-20 mA process signal through a standard ½" UNF-connector. Other ½" UNF connectors are installed for external high pressure, low-flow or run-dry protection. The brochure contains complete specifications and dimensions, common applications, and available options including sensors, connector cables, and "follower mode" software.
These units are available from stock for quick delivery.
