Progressive Cavity Pumps have integrated vector drive.
July 1, 2008 -
MD and BW pumps are available with drive that integrates single reduction gear reducer, 4-pole TEFC, inverter-rated ½ hp electric induction motor, and vector type variable frequency drive in NEMA 4 enclosure. Pump and drive combination, covering performance band of 0.08-4.7 gpm and pressures to 360 psi, operates from 1x120 Vac, 15 A circuits with 5-15p grounded plug. Drive has H-O-A switch with 10-turn potentiometer for manual control and will accept 4-20 mA process signal.

New Integrated Pump and Vector Drive
seepex has released a new integrated drive for its popular line of MD and BW progressive cavity pumps. The drive integrates the pumps with a single reduction gear reducer, a four-pole, TEFC, inverter-rated ½ HP electric induction motor and a "vector" type, variable frequency drive in a NEMA 4 enclosure. External or special fabricated control enclosures are not required for high pressure or run dry protection, so 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 unit operates from standard 1x120 VAC, 15 amp circuits with a 5-15p grounded plug. 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 sensors and connector cables, in various lengths, are also available from seepex.
The effective speed range of the units is 20-600 rpm. The "vector" capability of the VFD has an internal sensor-less feedback system for superior but economical speed control and stability. The gear reducer provides the unit with strong torque capability across the entire speed range. Unlike DC units, this unit has excellent speed control even in areas, like agricultural or oil field production fields, where input line voltages vary. There is also no concern for contamination or maintenance caused by the wearing of commutator brushes.
These units are available from stock for quick delivery.
