seepex has released a new integrated drive for its popular line of metering and general transfer 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.
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 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 accurate yet economical speed control and stability. The gear reducer provides the unit with strong torque capability across the entire speed range. 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.
