Seepex has released an integrated drive for its 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 1/2 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 0.08gph to 4.7gpm and pressures to 360lb/in2.

The unit operates from standard 1 x 120VAC, 15A 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 4-20mA process signal through a standard 1/2in UNF-connector.

Other 1/2in 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 20-600rpm.

The ‘vector’ capability of the VFD has an internal sensorless feedback system for 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 good speed control even in areas like agricultural or oil fields, where input line voltages vary.

There is also no concern for contamination or maintenance caused by the wearing of commutator brushes.
