This case study shows the ideal progression of a project from start to finish. Below are the basic steps that ultimately led to a successful project and happy customer.

  1. Initial contact through our website
  2. Discussions with customer to better understand the needs and application
  3. Review of product details
  4. Product testing at DDPS facility in Charlotte, NC to prove capability to handle customer’s product
  5. Testing was successful
  6. Customer moved forward with equipment purchase
  7. Detailed design of the system
  8. Shipment
  9. Customer installed and commissioned equipment with guidance from DDPS
  10. Customer has now been operating the system successfully since 2020


The customer referenced in this case study is a global leader in sustainable chemical solutions for water intensive industries with focus on pulp and paper, water treatment, and energy industry.


The customer needed a solution to transfer Sodium Gluconate into their process. Their product was to be handled in FIBC’s (Flexible Intermediate Bulk Containers) or bulk bags. There was no existing equipment at the facility to handle bulk bags and space available was minimal. The customer also needed a method to distribute product from one super sack to two different vessels.

De Dietrich Process Systems proposed a bulk bag unloading station with two Powder Pump conveying systems to transfer the Sodium Gluconate. We knew from in-house testing of the product that the material would flow easily. This meant enhancements like bag massage, vibration or fluidization would not be required and would help minimize overall cost of the system.

To further help with making this an economical solution, one single vacuum pump was provided to service both Powder Pump systems instead of two.

To feed each Powder Pump system, DDPS supplied all the necessary pipework. The pipework design included a 2-way diverter valve that enabled the customer to select which vessel needed to be fed.

Lastly, we supplied a complete control system with PLC and HMI. The HMI was designed to be intuitive and allow operators to input the information needed to operate the system. If the system needed to be serviced or troubleshooting was required, we also provided different access levels in the system to ensure these types of things could only be done by trained personnel.


From the onset of this project DDPS quickly became the desired partner for this project. By proving, via testing, that we could meet all the customer needs, we provided the confidence needed for the customer to choose us. The end result was a system that easily met all of their needs and made a daunting task much easier.
