How to solve some common problems in powder pump technology

It is said that the best teaching method is to set an example. So, what better way to show you the benefits of powder pump than to show some real case studies? These case studies show real customers in the real industry, and solve real problems with real processes and truly innovative solutions provided by DDPS. Well, I know I broke the blogging rules by blowing our own French horn, but if you’re looking for some real information about how Pneumatic Diaphragm Pump technology has improved in different processes, you may want to read on. These concise case studies will provide you with a snapshot of the customer / process context, the process issues you are facing, and the details of the solution.



Case study 1


a special materials and chemical technology facility in the southeast has a process involving charging multiple forms of the same powder from multiple locations to a single reactor. The transferred powder is phenothiazine (phenothiazine), a synthetic compound with two main uses: 1) as a veterinary drug for the treatment of parasitic infections in animals and 2) as a sedative for the treatment of mental disorders. There is a problem with their method of conveying powder mechanically, because too much dust is generated, resulting in high maintenance time and cost. In addition, the transfer distance is more than 100 feet (30 meters). Each form of the solution powder was transferred and tested at DDPS’s Charlotte, North Carolina facility, and witnessed by customers. The required transmission distance was replicated in this test. We provide our customers with an 8-inch powder pump made of stainless steel and an integrated human-machine interface for operation using PLC control system. HMI makes transfer settings through multiple screens, each powder has a dedicated screen. This customized solution enables operators to easily obtain the parameters established for each powder type and location. Once the transfer parameters are set, they become permanent in the system


Case study 2



Robinson Brothers Limited, a chemical contract manufacturer headquartered in West Bromwich, West Midlands, UK, is in the process of pouring various powders into multiple reactors through open artificial channels. The multi powders used in this operation have different characteristics. The problem of manually handling the powder creates a dusty environment and also requires high labor consumption to complete the necessary tasks to perform the process. There is also a problem with loading hazardous powders into reactors containing highly flammable solvents. The company is looking for an environmentally friendly solution that will maintain a closed system to remove dust, and an automated solution to free employees from the physical requirements involved in the process. After demonstrating powder pump technology at DDPS UK plant, a test facility was installed on site to transfer many of the powders used in production operations. After witnessing how our powder transfer technology can effectively move their powder, both reactors are equipped with DN250 powder pumps, both controlled by a single PLC control system with HMI. The powder pump and HMI panel are rated to be installed in ATEX zone 1 and PLC in safe zone.

If your plant is currently handling powder manually and using a potentially unsafe method, it is important to explore the option of internal delivery via a powder pump. For more information on this topic, please read our data sheet “advantages of pneumatic conveying, manual and mechanical charging.”. Here, you will learn about the advantages of  pneumatic powder pump, which enables you to transport powder safely and conveniently
