HPS Drive

Ensure your injection pump's peak performance
Injection Pump Applications → HPS Drive

SPOC Automation makes your saltwater disposal  or injection pumps work more efficiently and reliably.

Disposing of saltwater through injection applications puts incredible  stress and wear on the pump.  Traditional solutions run the pump at full speed and use a valve to choke back pressure to the optimum level. The SPOC HPS drive offers an alternative solution that greatly reduces wear on your system, helping you operate more efficiently.

The HPS variable frequency drive controls the speed at the pump, allowing you to leave the valve open at all times, reducing wear and failures within the system. The drive’s simple interface allows you to control and monitor your tank levels, vibration sensors, intake pressure and discharge pressure. You can now control the pump at the widest possible range.

Service is a vital component of the HPS drive. We understand what you face in the field. Our in-house engineers have extensive field experience. They know what you’ve faced, and we’ve designed our drives around your business.

With HPS, you get precise control over your system and your operators get better data, historical and run-time information than other drives on the market. HPS drives ensure the widest possible operating range for your pump system and reduce costly down time. The HPS drive is available with ModBus RTU and Ethernet communications, so you can tie the drives into your SCADA system or Well Optix.


Testimonial: M4 Equipment

Speaking about how their company bridged the gap between manufacturer and end-user with SPOC’s products.

With the HPS drive, you can:

  • Use traditional oilfield switches and gauge controls, or fully automate the pump system with more accurate pressure transducers with analog outputs.
  • Reduce peak demand charges from utility and energy consumption when compared to across-the-line starters.
  • Reduce inrush currents to the name-plate amps of the motor; that is seven to 12 times less than starting the H-Pump with an across-the-line starter.
  • Save money by running the pump at the optimal speed rather than just an on/off control.

After years of continued development and listening to our customers, we can say, “It’s in there.” The HPS drive is the industry’s best tank level, pressure control, feature-rich surface pumping system drive on the market. We asked our customers what their wish list would be for their horizontal pumps, triplex and other injection/disposal applications. The final result is the HPS Series Drive, which has everything you need to produce more and spend less. Below are some of the most critical specs to evaluate the HPS drive with.

Dealing with the people at SPOC has been fantastic. You don’t feel like you’re left alone with the technology. It’s been like no other support we’ve ever had with any other company.

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.

Well Optix

SPOC's SCADA package gives you better data and more control over your wells

Well Optix: SPOC's SCADA package gives you better data and more control over your wells

Well Optix is our SCADA package designed to perform remote monitoring, historical data acquisition, while also controlling artificial lift and other oil and gas field applications. Well Optix gives you actionable production data that can enhance your profitability. It’s powerful, yet simple to use, allowing you to remotely make changes depending on well conditions, maximizing your uptime. In addition, we have experienced field engineers on staff who can help guide you should problems at the well arise.

Well Optix can:

  • Trend production optimization data on your well 24/7
  • Make well data available instantly from any internet connected device
  • Make production notes about significant events, keep current logs on well equipment and set email or text alerts to notify you when conditions hit your specified thresholds.

WiseGuy HP

The easiest, most detailed VFD interface available
Comes standard with every HPS Drive

WiseGuy HP: The easiest, most detailed VFD interface available

With every piece of SPOC technology, one of our most important goals is to make the technology easy to operate. The WiseGuy HP drive interface is intuitive and simple, making it easy to gather data on your wells and make changes to the operation of the drive. The touch screen drive interface is the most user-friendly on the market.

Smart. Intuitive. Easy. These are the most common words customers use to describe the WiseGuy. If you use industry terminology like SPM (Strokes per Minute), “Pump Run Time” (“Real Time Run Time”), and “Number of Pump Offs,” you can program the drives. It’s really that easy. We can provide customized injection pump packages to meet your specific application requirements.

WiseGuy VFD interfaces come in standard keypad and logic control versions. Not only is the WiseGuy a “know it all,” but it can also make decisions that will keep your equipment running at peak performance and production. These are some of the standard WiseGuy HP screens and I/O configurable points with the HPS drive package:
