Roto-Armor Drive

Tough. Dependable. A true workhorse.

The Roto-Armor drive solution for progressive cavity pumps is easy to use, incredibly reliable and promises the twin benefits of reduced down time and major energy savings.

Roto-Armor variable frequency drives means you may never have to shut down your progressive cavity pump. Roto-Armor allows you to slow the pump, if enough fluid is available in the well, rather than stopping the motor. Roto-Armor has a self-teaching mode that will run the pump at optimal speed for each well’s inflow rate to maximize production.

We have customers that have eliminated backspin at pump off or gas shot interference by using our variable frequency drives. In most cases, this will extend the life of the equipment, while increasing your production, getting you the maximum return on your investment. What’s more, there are no costly sensors to install on the unit that can be damaged, rendering the unit inoperable.

Reduced Wear; Reduced Energy Cost. The Roto-Armor VFD has highly accurate motor control to carefully regulate applied motor torque, eliminating torque overshoot and its associated problems. We can reduce belt, rotor and rod string breakage from excess torque, saving service costs and increasing production. With near unity power factor, elimination of inrush currents and associated peak demand charges, and a reduction of utility kwh usage, the Roto-Armor VFD means payback is quick. Factor in precision speed control over the pumping process, and you also create the opportunity for increased production.

Programming and operating the Roto-Armor VFD is easy and intuitive. This drive was designed to be used on progressive cavity pumps, using oil field units of measure your pumpers already know such as “Motor RPM,” “Rotor Speed,” or graphing the data on the WiseGuy. Built-in production calculations assist in evaluating wells. The Roto-Armor is also available in single phase input, eliminating the need for costly, problematic phase converters and the associated over-sizing of components or motors. Additionally, those traditional methods cost you more on your O&M budget dollars due to the high electrical losses that accompany them.

WiseGuy DL

The easiest, most detailed VFD interface available
Comes standard with every Roto-Armor Drive

WiseGuy DL: The easiest, most detailed VFD interface available

Smart. Intuitive. Simple.

That’s what customers are saying about the WiseGuy DL VFD interface that is optional on Roto-Armor drive packages. If you know industry terminology like “Shaft RPM,” “Run Time History” or “Pump Offs” then you can operate the WiseGuy DL. It’s that easy. Knowledge is power in the hands of your pumpers and the WiseGuy DL gives you live trending, history, date & time stamp, data logging, single touch USB downloads, and much more in the industry’s easiest to use, smart and intuitive drive package.

Using the WiseGuy DL, the most recent 30 day production history and up to the last 97 pump off events are graphically viewable and downloadable.


Our low-harmonic drives keep you running reliably, efficiently and in compliance

Harmonics: Our low-harmonic drives keep you running reliably, efficiently and in compliance

Harmonic drive compliance becomes more critical every day. At SPOC, we focus on the entire system, providing low-harmonic drives to ensure that you continue running reliably, efficiently and in compliance of IEEE519 and EN-6100-3-2.

We can perform studies for new or existing systems, as well as harmonic measurements to help you get a baseline of your current power quality. Using harmonic modeling tools, we can help you evaluate different scenarios and supply you with the right products that will help you run in compliance with the harmonic standards, with the highest reliability and at the right cost.

We manufacture every type of low harmonics drive, using the latest technology available.  Everything we do is tailored to your needs.

The Active Front End VFD is SPOC’s recommended approach for minimizing harmonics in fields where all lifting is done using variable speed drives. This technology is electronically based, not magnetically based. It meets the IEEE519 under every scenario and all loading conditions, regardless of voltage imbalance or source impedance. It is so advanced it can actually correct for low-voltage conditions from marginal systems and correct power factor within the electrical system, saving you money. We have years of experience in Active Front End Drives, and can do systems from 1HP to 2000HP at 480V.
