Starting and Stopping is Tearing Your Pumping Assets Apart

Constantly starting and stopping your pump over the life of a well subjects your assets to an incredible amount of stress. It will literally shake the bolts loose over time, not to mention wreak havoc on the vital (and very expensive) pieces of machinery that you depend on to maintain production.


Pump Protections Inherent in your VFD

You’ve got a lot invested in your assets in the field and you want to protect those assets as much as possible. Of course. One critical layer of protection for your pumps, no matter what kind of pump you are using, resides in your variable frequency drive and its associated automation.


The Savings Are Real. And They Are Spectacular.

When we talk about the primary benefits of adding a drive to your rod pump applications, those benefits come in two flavors: cost savings and increased uptime. There are other benefits, however. Less stress and wear on your equipment mean things break less often so your maintenance costs go down and you get more from your investment.


The Cost of Damage from Rod Float

The energy unleashed on your equipment from unchecked rod float is tremendous. The cost of repairing the damage is equally sobering. Consider a typical case.


SPOC Saves Producer $17 Million on Oilfield Project

In today’s cost-sensitive environment, it is more important than ever to improve your field’s efficiency and look at the overall economics.  By using SPOC drives, a project originally budgeted at $25 million comes in around $8 million. Is saving $17 million on a project possible by using SPOC drives? Watch the video and see how the results speak for themselves. 


Can Drives Take Single-Phase Power and Operate Three-Phase Motors?

Oilmen go where the oil is. Often that means remote, rugged or rural areas—sometimes all three. It should not be surprising, then, that power services may be limited or lacking altogether.


Soft Starters are Cheaper but They Cost More


Soft Starters have an initial attraction because of their low unit price. For a few thousand dollars, operators can add better start and stop control to their pumping units.


How Pump Off Actually Works

Pump off has traditionally been the term used to describe the condition when a pump must shut off to protect itself after the surplus liquid is removed from the annulus or casing. This has the effect of generating an unbalanced condition where there is a sudden change in the normal torque required of the motor.


Safety Features in the IronHorse VFD for Beam Pumps

Safety Features in the IronHorse Variable Frequency Drive for Beam Pumps

The IronHorse drive provides several safety features.

  • Termination point for local field safety shut downs. Most pumping unit installations include local field safety shut downs. These can include: environmental protection (‘enviro-pot’), vibration switches, flow line switches and tank battery shut downs. The IronHorse (IH) provides a termination point for the local field safety shut downs as a standard feature. If the end user has several safety kills they prefer to use at one time, all field safeties can be ran in series and provide VFD shut down.

  • Control (local or remote) lockout. The IH provides an HOA switch (Hand-Off-Auto). This feature lets the pumper prevent a switch from local to remote control (or vice versa), which can very important while working on a well. For example, if the pumper is on site doing a maintenance repair nobody should be able to startup the drive remotely. This is an important safety feature, for both the pumper and the pumping unit itself. It is also important that the pumper be able to switch to local while on site when the VFD unit is not near the pump itself. That way the pumper can adjust settings while directly observing the equipment, and it is important that nobody at this point be able to make changes directly to the drive.
