Keep The Well
Producing.
Water-laden wells need pumps that run continuously, adapt to rising water cuts, and pump through demanding conditions. Phase drives keep dewatering systems running without the need for brake resistors and nuisance faults while using power factor correction for reduced energy usage.
Water-Cut Kills Production When Drives Can't Keep Up.
As a well matures, water cut rises. The pump that was right-sized at first-production is now cycling, cavitating, or working at dead-head against a slug of water that changes volume hour to hour. Standard drives can't adapt.
In remote locations like saltwater disposal wells, coalbed methane, produced water, a tripped drive means standing water, backed-up production, and long distance service calls.
- Fixed-speed pumps cavitate as water cut changes through the day
- Nuisance overload trips on slug flow and varying fluid density
- Braking resistors corrode and fail in outdoor enclosures
- No remote visibility means unknown downtime on unmanned saltwater disposal sites
Variable Speed That Follows The Well.
A Phase VFD modulates pump speed continuously, matching output to actual inflow rate, whether that's a trickle between frac jobs or a full surge after stimulation. Soft-start on every cycle eliminates the inrush and mechanical shock that wear out pump seals and motor windings.
The LHX Series active front end handles the regenerative events that occur when a pump decelerates against a full column of fluid, returning that energy to the grid instead of burning it in a brake resistor. Phase Connect gives your production team live run status on every unmanned site.
- Variable speed matches pump output to real-time inflow, eliminating cavitation
- Soft-start eliminates inrush and motor winding stress on every cycle
- LHX Series handles regenerative braking meaning no braking resistors to replace
- Adjustable current limits handle slug flow without nuisance trips
- Phase Connect cellular monitoring shows every site's status remotely
What Phase Brings To
Oilfield Dewatering
Variable Speed
Continuously modulate pump speed to match actual water inflow. Run fast when water cut is high, slow when the well is making less. No cavitation, no dead-head.
Soft Start
Every pump start ramps torque gradually, reducing inrush spikes, and mechanical shock on couplings, seals, or the motor. Critical for submersible and vertical turbine pumps.
Slug Flow Tolerance
Adjustable current limits and torque boost settings absorb slug flow events without nuisance trips, keeping the pump online through variable fluid density.
Phase Connect
Cellular remote monitoring for unmanned saltwater disposal and produced water sites. Run hours, fault history, amp draw, visible from any browser, no site visit required.
Outdoor Rated
NEMA 3R enclosure for saltwater-laden, UV-exposed oilfield environments. Corrosion-resistant, rated for the temperature extremes of the field.
Low Harmonics
LHX Series meets IEEE 519 natively. No external filters. Important when multiple dewatering drives share a common pad transformer on a multi-well site.
No Braking Resistors
The LHX Series regenerative front end handles pump deceleration against a full fluid column without braking resistors. Nothing to corrode, nothing to replace.
SCADA / Modbus
Standard Modbus RTU/TCP for integration into field SCADA. Monitor current draw, speed, fault codes, and run time from your existing production software.

Built In‑House.
Need more than a drive? Our UL 508A panel shop builds complete, listed motor control assemblies, including VFD, bypass, HOA, motor protection, and wiring, engineered for your pump HP, input voltage, and NEMA rating.
One Manufacturer from the Drive to the Finished Panel
Choosing the correct pump drive involves more than matching horsepower. Incoming voltage, phase availability, pump type, motor lead length, pressure requirements, environmental conditions, harmonic limits and control preferences can all affect the final system design.
Phase Technologies offers residential drives, general-purpose DXL drives, low-harmonic LHX drives, phase-converting systems, voltage-doubling configurations and customized control panels from a single U.S. manufacturer.
Whether you need constant pressure for a home, three-phase motor control for an irrigation well or a customized low-harmonic panel for a municipal pumping station, our team can help configure a system around the way your site actually operates.
Built In The USA
Proudly American Made
Every Phase drive is engineered, assembled and tested at our Rapid City, South Dakota headquarters — with the industry’s fastest lead times.
