BENCO Motor Controllers

Simple. Hands-On. Rate Control.

The most reliable controller on the market for over 10 years running.

Control your 12V pump with the twist of a knob.

BENCO MSC30-DD Motor Controller with digital display manually controls your pump with a turn of a dial.

BENCO's Motor Controllers are a simple and inexpensive way to manually control your 12V pump from the cab of your tractor. 

The idea is simple. We vary the amount of power going to the pump on your system, like a dimmer on a light.

Just turn the knob on the control box whenever you need to adjust your flow rate. This gives the pump more or less juice and turns the system pressure up or down, changing the application rate.

If you want to stop pumping, just flip the toggle switch to off. When you turn it back on, it will still be set at the same rate.

This may not be as advanced as fully automated systems, but it achieves similar results for a fraction of the cost.

BENCO Motor Controllers give you fine-grain control over system pressure, but without all the expense and complexity of flow meters, field computers, wiring harnesses and complex plumbing.

This is an ideal companion to OnSite FMS, which monitors the exact flow rate of liquid going to each row in real time. With BENCO Motor Controls varying pressure and OnSite monitoring flow rates, you get full application rate control and real time monitoring of your application rates without the expense of a full precision ag system.

Take control of your liquid with a BENCO Motor Controller!

Why Use a BENCO Motor Controller?

You are in control.

Motor controllers are old-school by design. They are an affordable hands-on solution to the problem of controlling the liquid going out to your field.

They allow you to target and control your application rates manually.  BENCO Motor Controllers give you similar fine grain control of your liquid application rates as a full precision ag setup, but for a small fraction of the cost.

Because our system varies the pump output directly, we can adjust system pressure faster and and maintain it more accurately than the traditional butterfly valves. As an added bonus, you’ll generally see longer life from your pumps as well.

  • Add real control to your sprayers & fertilizer application without changing your system  
  • Gives you complete control with a single knob right in your tractor’s cab for quick access
  • Ideal for the smaller operator who wants better control but can’t justify the high costs of a full precision system 
  • Analog or digital meter for precise control 
  • Controls motor speed on any 12V electric pumps
  • Varying the pumps gives quicker, more accurate adjustments while helping increase pump life 
  • PWM version integrates with existing field computers to free up hydraulic circuits while giving more precise control
  • Vary your spray pressures on the fly from the comfort of your cab 
  • Get more precise pressure control and faster adjustment
  • Use with OnSite Flow Monitoring System for real-time feedback of true liquid application rates

You know your fields. You know how you want to apply chemical to them. BENCO Motor Controllers give you the ability to achieve extremely accurate application rates in the field for a few hundred dollars instead of many thousands of dollars.

BENCO MSC30-NG Motor Controller does not have a gauge, but is a perfect companion to OnSite FMS or any system where pressure or flow rates are monitored independently.

A simple, economical choice.

Precision farming is great. It can help every field produce at its maximum potential. However, the systems are extremely expensive and complex. They just don’t make sense for many smaller farmers.

BENCO’s Motor Controllers are a simple alternative to the expense and complexity of a full precision setup. You can get the same precise control your application rates for a few hundred dollars rather than many thousands of dollars. The system often pays for itself the first year, even for a smaller farmer.

Not only is the BENCO Motor Controller extremely affordable, it replaces expensive hydraulic pumps with more affordable electric pumps, potentially saving you thousands on the pump and freeing up a hydraulic circuit on your tractor.

  • Simple, single knob interface
  • Works with your existing setup
  • Frees up a hydraulic circuit
  • Uses less expensive electric pumps
  • No additional computers or components needed
  • PWM controller integrates with most existing field computers
  • Easy to set up. Easy to move between machines

Universal Application & Easy Installation

BENCO Motor Controllers work with any system that uses electric pumps, regardless of manufacturer. The BENCO Motor Controller simply plugs inline between the battery and the pump. It controls how hard the pump runs by controlling the power supplied to the pump. No additional hardware to upgrade. No changes to your plumbing.  

BENCO Motor Controllers include a BENCO custom wiring harness to make installation a breeze. If you do run into problems, our skilled techs are here to help get your system up and running in no time.  

  • Add more control to any existing system that uses an electric pump
  • Works on both planters and sprayers
  • Our custom wire harnesses make hooking up to any system a breeze
  • All wires feature high quality weather-tight connectors
  • 30 amp max
  • Easy access fuse protects unit from power overloads 
  • Motor & battery extension cables available to make installation easier. 
  • BENCO stands behind our system with full support 
BENCO MSC30-MOD Motor Controller uses a PWM signal from your field computer to vary the output of your pump and control your application rate.

Go electric and free up a hydraulic circuit with a PWM Controller

If you already have a precision ag setup, but are out of hydraulic circuits, a BENCO PWM Motor Controller may be the perfect solution. Switching your hydraulic pumps to electric not only frees up a hydraulic circuit, but can actually give you better control when paired with a PWM Controller.

BENCO’s PWM Motor Controller takes the universal Pulse Width Modulation feed from your existing field computer and uses it to precisely vary the output of the electric pumps running your planter or sprayer.

A BENCO PWM Motor Controller replaces the traditional regulating valve by adjusting the pump pressure directly. Regulating the pumps themselves gives you faster, more precise application rate adjustment than a traditional butterfly valve setup while increasing pump life. Our PWM Controller is compatible with ANYTHING that puts out a PWM signal. 

Save money, get more control, and free up a hydraulic circuit with a BENCO PWM Motor Controller.

OnSite FMS and a BENCO Motor Controller are a marriage made in liquid-handling heaven.

  • Your BENCO Motor Controller will precisely adjust the pressure in the system.
  • OnSite FMS precisely monitors the flow rates going to each nozzle.
  • When combined, you get extremely fine-grain control of your application rates that is easy to adjust on the fly with the twist of a knob.

This is such a perfect combination, that we usually recommend buying these together if you run a 12V pump.

When you combine the precise pressure control from the BENCO Motor Controller with the full visibility of OnSite FMS, you get simple, manually controlled precision liquid application. This combined system can achieve similar application rate control to a automated setup for less than the cost of the field computer alone on other systems.

  • Control your application rates.
  • Control your input costs.
  • Control your equipment costs.
  • Control your profitability. 
Take back control of your field with OnSite and BENCO.
