How FMI Pumps Integrate into OEM Systems

Can pumps integrate into OEM systems?

It's a question that we often receive, as end users want to customize the pump as much as possible so that it works better for them. And while this can be done, there are many considerations that need to be weighed before it's carried out. In this post, we'll cover how pumps integrate into OEM systems, how to know what pumps to integrate and more. Here's a closer look:

Can FMI Pumps Integrate into an OEM System?

icst-02The short answer: yes.

Pumps are typically configured by selecting a motor drive and a pump head. This is done to ensure that the pump assembly is capable of providing the correct flow and dispense volume. However, the pump is only one piece of the puzzle as most OEM systems will require some type of stepper controller.

Fluid Metering offers what we call the ICST02 as a controller option; however, customers are not limited to what we offer. Many applications will utilize some of the vast options available on the market for off the shelf controllers. Other applications will develop their own controllers to better fit their application. 

Pumps are typically sold as a mechanical unit and can be configured with various motors and pump heads. These pump heads are driven by a stepper motor, which requires a separate controller to operate. The stepper motor helps to adjust speeds and can help with either increasing or decreasing flow rates, dispensing volume, and more. There are plenty of off the shelf stepper controller options that enable users to send live commands to the stepper motor/ pump to direct it on what to do.

End users can develop their own stepper motor controllers and there are applications where users purchase one off the shelf. Others utilize FMI stepper motor controller if it fits the application requirements.

Essentially, a pump is looking for stepper controller signals, and whatever controller a user decides to implement simply needs to be capable of working with a stepper motor.


How to Integrate FMI Pumps into OEM Systems

In most cases, there are two types of motor drives that can be integrated into OEM systems. These drives require separate methods for integration. Here's a look at the two options:

  • Stepper motor controller must be capable of 2 or 3 phase control for most standard stepper motors. Additionally, the controller should have provisions to include an optical sensor and or inputs and outputs open or closed loop systems.
  • DC motor drives require a motor controller that is capable of varying voltage to control the motor speed.

Keep in mind that the controller you choose needs to have the ability to drive the stepper motor and the optical sensor. For DC motor drives, users need to have a voltage controller of some type to vary the voltage that is supplied to the motor to control speed and other variables.


Can the FMI ICT02 Controller be Integrated?

Yes, this can most definitely be integrated into an OEM system or a large instrument. However, it may have some limiting factors depending on what your requirements are. If you're not looking to constantly change your parameters throughout the system, the ICT02 could be the ideal solution for you. You would need to pre-program the controller to the parameters that you plan to operate at, and that would trigger the function as needed throughout the system - regardless of what it's connected to.


Can the Controller Integrate with a Programmable Logic Controller (PLC)? 

In order to communicate with the ICST02, the PLC would need to have RS485 communication capabilities. If your PLC has the ability to send communication over serial terminals, then you should be able to connect and integrate the controller into your PLC. Just make sure that you do your homework beforehand, so you have a better understanding of how it integrates.


How Do I Know What FMI Pump to Choose to Integrate?

oem_pump_sq1FMI offers a wide range of pumps when it comes to flow rates, dispense volumes, flow characteristics, and other variables. The type of pump you choose to integrate really depends on what you're looking to achieve with your instrument. End users should be asking questions, such as:

  • What's the target flow range?
  • What's the target dispense volume?
  • What's the fluid type?
  • What is the required duty cycle?
  • What pressure flow rate is needed?

By knowing this information, our experts at FMI are able to narrow down the pumps that would be applicable to your needs. We encourage you to reach out to one of our experts to determine the best fit for your application. There are many different combinations to navigate when it comes to pump availability, and it's always best to get some expert advice so you're not left guessing at what type of pump would work best.
